Killstreak Challenges - Level 16, Part 1
These challenges relate directly to the killstreak rewards you unlock as you progress through the game. Don't have a killstreak unlocked? Don't worry, by level 70 you'll have all of them unlocked. Wondering what killstreaks are? Check out this guide to multiplayer Call of Duty. Looking for a good review instead? Try this Modern Warfare 2 review.
These rewards deal with Killstreaks, which are rewards acquired when you kill enough people in a row without dying. Every killstreak is represented. This section deals with the challenges which are unlocked at level 16. General advice for all killstreaks is to be patient and cautious. If you need to, use Hardline, though for the later killstreak rewards it won't likely help too much. If you can't get to 7 kills for a harrier, the difference between 10 and 11 for a chopper gunner is minimal.
Exposed I, II, and III - Call in 5, 25, and 50 UAVs. Worth 1,000, 2,500, and 5,000 EXP respectively. Challenge I unlocks the Overwatch title, challenge II unlocks the Voyeur title, and challenge III unlocks the animated UAV emblem. There's really no good tip for getting UAVs. Hardline means every time you kill two people after you spawn you get one. Get them, call them in, and work on higher killstreaks. If you die, your UAV may still be in the air, and you can hunt down a few people to kill for a new one. Piece of cake.
Air Mail I, II, and III - Call in 5, 25, and 50 Care Packages. Worth 1,000, 2,500, and 5,000 EXP respectively. Challenge I unlocks the DZ Clear title, challenge II unlocks the Companion Crate title, and challenge III unlocks the animated Care Package emblem. Much like the UAV challenge, care packages are relatively easy to call in. In most cases, when you call in a care package, the killstreak you get from it also counts toward that killstreak's challenge. This makes care packages a relatively fast way to get some progress towards challenges. However, the likelihood of high-level killstreaks such as an AC-130 or an EMP are slim, and you're more likely to get UAVs, Counter UAVs, and Ammo resupplies.
Interference I, II, and III - Call in 5, 25, and 50 Counter UAVs. Worth 1,000, 2,500, and 5,000 EXP respectively. Challenge I unlocks the Givin Static title, and challenge II unlocks the SIGINT title. Challenge III unlocks the animated counter-UAV emblem. Counter UAVs aren't quite as useful as the other low level killstreaks, but they can still be helpful. For players that rely on a UAV, or even just looking at their radar, a counter-UAV is a godsend. Using these can help a stealth class, specifically with Ninja. Having no radar on the enemy team and having them unable to find you with a heartbeat sensor makes you virtually invisible.
Sentry Veteran I, II, and III - Call in 5, 25, and 50 Sentry Guns. Worth 1,000, 2,500, and 5,000 EXP respectively. Challenge I unlocks the Hands Free title and challenge II unlocks the Fire and Forget title. Challenge III unlocks the animated sentry gun emblem. One thing to note is that this requires you to throw the flare to call in the sentry box, not to be the one to place the sentry gun itself. This means that stealing an enemy care package, or even an ally emergency airdrop package, won't count towards the challenge. Additionally, if you place a sentry gun and die, your sentry gun kills won't count towards a new killstreak reward. This makes chaining sentry guns difficult. However, using a sentry gun to protect one entrance to your hiding spot and watching the other yourself can make you a kill machine. Just watch out for players using cold-blooded, as sentry guns won't spot them.
Air To Ground I, II, and III - Call in 5, 25, and 50 Predator Missiles. Worth 1,500, 2,500, and 5,000 EXP respectively. Challenge I unlocks the Rain of Fire title and challenge II unlocks the Ghostrider title. Challenge III unlocks the animated predator missile emblem. Predator missiles are the first real offensive killstreak you get. If you're lucky and know where players tend to congregate, you can easily get two kills, which will then net you a harrier, killing two birds with one stone. These are a good way to kick off other low-medium level killstreaks, and they come unlocked for you when you start, so you should be able to complete these challenges with a minimum of effort. Just focus on staying alive and you'll get them in no time.

Killstreak Challenges - Level 16, Part 2
Airstrike Veteran I, II, and III - Call in 5, 25, and 50 Precision Airstrikes. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge I unlocks the Time on Target title, and challenge II unlocks the Broken Arrow title. Challenge III unlocks the animated precision airstrike emblem. This challenge is interestingly placed, as Precision Airstrikes are later in the list than harriers. However, they are arguably just as useful. Unlike harriers, with precision airstrikes you can choose not only where the explosions land, but what direction the planes fly. This means you can direct them down narrow alleyways and long roads, instead of across buildings where most of the explosions land on rooftops. Coupled with a UAV to tell where the enemies are, and you can probably average two or three kills with one airstrike. This is especially useful for open maps like Invasion, Quarry, and Wasteland.
Vertical Takeoff I, II, and III - Call in 5, 25, and 50 Harriers. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge I unlocks the Jump Jet title, and challenge II unlocks the Straight Up title. Challenge III unlocks the animated harrier emblem. Harriers are one of your best early killstreaks. At seven kills, they take a bit of effort to get, but against most unprepared teams they can get a number of kills. The initial airstrike can get two or three if you're lucky, and the hovering plane can kill many more, especially in regular team deathmatch and ground war modes, where players seldom run with Stingers or Cold Blooded. A well-placed and lucky harrier can pave the way to a Chopper Gunner or AC-130, completing those challenges as well. Focus on surviving, first and foremost. If you're still having trouble with them, use predators and UAVs instead of higher level killstreaks, and focus on the harrier as your end goal.
Attack Helicopter Veteran I, II, and III - Call in 5, 25, and 50 Attack Helicopters. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge I unlocks the Reign Down title, and challenge II unlocks the Squawk Box title. Challenge III unlocks the animated helicopter emblem. Attack helicopters are seldom used and seldom effective, which makes them hard to use as a gateway to later killstreaks. In general there are better streaks to pick. When you use them, you should only expect a couple of kills before they're shot down. This is because they tend to wander slowly around the map, and they don't shoot very often. Use predators and harriers to work towards an attach chopper, and don't rely on the chopper to get you to anything higher.
Special Delivery I, II, and III - Call in 3, 10, and 25 Emergency Airdrops. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge I unlocks the Share Package title, and challenge II unlocks the Philanthropist title. Challenge III unlocks the animated emergency airdrop emblem. Emergency Airdrops are very useful for several reasons. First, they can drop a number of good care package rewards. Second, they can work effectively as a lure for the enemy team, if your team doesn't pick them all up quickly. Third, if your teammates pick up one of your packages, YOU get additional EXP for it. The formula 50 exp per kill it would take to earn the reward, so a UAV, which takes 3 kills, would net you 150 exp if your partner takes it. Meanwhile a chopper gunner, at 11 kills, would net you 550 exp. With four packages, it's usually most effective to take the best one for yourself and let your teammates take the rest. To get an emergency airdrop, a predator and a harrier one after the other will usually do it.
21 Ton Giant I, II, and III - Call in 3, 10, and 25 Pave Lows. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge I unlocks the Airborne title, and challenge II unlocks the Flying Tank title. Challenge III unlocks the animated pave low emblem. Pave Lows are the first air support killstreak that's hard to shoot down. They have flares, which will distract one lock-on missile from hitting. This makes them tough and dangerous in the air. Players without cold-blooded are likely to fall. Pave Lows are a good streak for getting you to higher streaks. Think of it like a more deadly version of the attack chopper, and you know what to do.

Killstreak Challenges - Level 21, Part 1
Just like the previous section, this section deals directly with your killstreaks. This uses the more advanced killstreaks such as the AC-130 and the Tactical Nuke, as well as group challenges, that have you call in any sort of airstrike, or any sort of radar manipulation. This selection of challenges is unlocked at level 21.
Stealth Bomber Veteran I, II, and III - Call in 3, 10, and 25 Stealth Bombers. Worth 1,500, 3,000, and 6,000 EXP respectively. Challenge II unlocks the SBD title. Challenge III unlocks the animated stealth bomber emblem. Stealth bombers are one of the best airstrikes. They're slow, but you can guide their direction like a precision airstrike. They don't show up on the enemy radar, so they have no idea where it's coming until it's on top of them. It also has the widest area of effect of any airstrike. This, like most higher level killstreaks, you may want to use predators and harriers to get to.
Chopper Gunner Veteran I, II, and III - Call in 3, 10, and 25 Chopper Gunners. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Get To Da Choppah! title, and challenge II unlocks the Cobra Strike title. Challenge III unlocks the animated chopper gunner emblem. Chopper Gunners are extremely good. While you're unprotected when you're using it, that doesn't matter, as you're likely to easily get 5-10 kills with it. You may get fewer if the enemy team is entirely running cold blooded and able to shoot down your chopper, but that's not too likely. Most people will use the chopper gunner as a step towards getting a Nuke. If your goal is the chopper gunner, use predators and harriers. If not, harriers are perhaps the best to get you where you need to be.
AC130 Veteran I, II, and III - Call in 3, 10, and 25 AC130s. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Godhand title and challenge II unlocks the Angel of Death title. Challenge III unlocks the animate AC130 emblem.AC130s are arguably better than the chopper gunner, and are often used for the same purpose. Unfortunately they take more skill to use and are highly map dependant. A mostly indoor map like Karachi, Favela, or Skidrow make it hard to use. Meanwhile a map like Wasteland or Derail is likely to be completely stalled by a well-used AC130. Again, either use predators and harriers to get to the AC130, or use a harrier and the AC130 to get to a higher streak.
Blackout I, II, and III - Call in 2, 5, and 10 EMPs. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Chick Magnet title, and challenge II unlocks the Starfish Prime title. Challenge III unlocks the animated EMP emblem. EMPs are one of the top two killstreaks in the game. Second only to the tactical nuke in kills needed, they aren't as useful as you might hope. They kill enemy electronics, including red dot sights, hearbeat sensors, and thermal scopes. They eliminate most of the enemy HUD, and make it impossible for the enemy to call in air support. They will also knock enemy air support out of the sky if it's already present. However, they're hard to get. At 15 kills, your best bet may be to use a harrier and chopper gunner, or AC130, to get where you need to be.

Killstreak Challenges - Level 21, Part 2
Endgame I, II, and III - Call in 2, 5, and 10 Tactical Nukes. Worth 5,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Global Thermonuclear War title, and challenge II unlocks the End of Line title. Challenge III unlocks the animated nuke emblem.Ah the Nuke. This has been the subject of more than a little grief and boosting. It takes 25 kills to get, and is quite difficult to do. Unfortunately, right now most of the people who have the third challenge complete boosted to do it. The most reliable method for gaining a nuke outside of boosting is to use a harrier and a chopper gunner. Focus above all else on staying alive, and pick a relatively small area to defend. Kill people until you have the harrier, and then call it in wherever you think it'll do the most good. Once you get your chopper gunner, find a safe place to hide and use it. If you're lucky, you can ride the gunner all the way to 25. If not, be very careful, but don't make stupid mistakes. It's frustrating to no end to get killed at 23 kills. Patience is your friend.
Radar Inbound I, II, and III - Call in 50, 100, and 1,000 UAVs or Counter-UAVs. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Omnipotent title, and challenge II unlocks the The Watchmen title. Challenge III unlocks the toon price emblem. These challenges simply involve time and calling in a massive number of UAVs and Counter-UAVs. Luckily these are low level killstreaks, and you're likely to get a few every map. Just keep plugging away and you'll get them.
Airstrike Inbound I, II, and III - Call in 50, 100, and 1,000 Precision, Stealth, or Harrier airstrikes. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Plane Whisperer title, and challenge II unlocks the Rolling Thunder title. Challenge III unlocks the treasure map emblem. Calling in this many airstrikes is difficult, but not impossible. Harriers will likely make up the bulk of your points toward the challenges, but if you run with both harriers and precision or stealth airstrikes, you can try to get two per life. Just keep working for it.
Helicopter Inbound I, II, and III - Call in 50, 100, and 1,000 Chopper gunners, pave lows, or attack helicopters. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Full Throttle title, and challenge II unlocks the Eyes Above title. Challenge III unlocks the green bird xray emblem. Calling in this many helicopters is tedious, but possible with a little time. Pave Lows are good to use anyway, and chopper gunners can get you a large number of kills, so chances are you'll be using at least one of the streaks necessary for these challenges already.
Airdrop Inbound I, II, and III - Call in 50, 100, and 1,000 Care Packages, Sentry Guns, or Emergency Airdrops. Worth 2,500, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Charity Case title, and challenge II unlocks the Pro Gambler title. Challenge III unlocks the gold ingot emblem. This is perhaps the most fun of the challenges to complete. Nothing is quite as fun as telling your teammates to gather, while having your streaks set to 4/5/8; in other words, care package, sentry gun, and emergency airdrop. Get eight kills, earn all the rewards, and call them all in at once. Instant Christmas. The wealth of useful killstreaks that come of it will probably push your team significantly into the lead. Try it out, and the challenges will be complete in no time flat.

Precision Challenges - Level 26
The Precision challenges involve feats of accuracy. For this first string of challenges, unlocked at level 26 in your upward progression, you'll be required to gain headshots, as well as the interesting set of accuracy challenges. These challenges require you to fire every bullet in a clip for a specific type of weapon, and to hit an opponent with each bullet. Having trouble with individual gun challenges? Try part one of the series.
Assault Expert I, II, and III - Headshot 5, 25, and 50 players with assault rifles. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Faceoff title. Challenge II unlocks the Crackin' Skulls title. Challenge III unlocks the ranger helmet emblem. This should be unlocked relatively easily as you complete the individual Expert challenges for assault rifles.
SMG Expert I, II, and III - Headshot 5, 25, and 50 players with SMGs. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Headrush title, challenge II unlocks the Pop Off title, and challenge III unlocks the british WW2 helmet emblem. These, like the assault expert challenges, will be unlocked as you complete individual expert challenges for SMGs.
LMG Expert I, II, and III - Headshot 5, 25, and 50 players with LMGs. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Not in the Face! title. Challenge II unlocks the Boom! Headshot. title. Challenge III unlocks the army helmet emblem. Again, like the above challenges, these will come naturally with the other LMG expert challenges.
The Surgical - Fire an entire Assault Rifle magazine into enemies without missing. Worth 2,000 EXP. Unlocks the Surgical title and the bandolier emblem. This challenge can be reasonably difficult. Use burst fire whenever you can on the automatic weapons. Alternately, use the burst-fire guns or the FAL. If you want, you could use the SCAR-H, as it has a low clip size. Just be careful to not fire more shots than you need to. Reloading does NOT kill your chances. The challenge is actually to hit X number of bullets in a row, where X is the clip size. The same holds true for all the full-clip challenges.
Mach 5 - Fire an entire SMG magazine into enemies without missing. Worth 2,000 EXP. Unlocks the Mach 5 title and the Rapid Fire emblem. This is slightly easier than the assault rifle version, because SMGs tend to have less ammo and do less damage. Their kick can make them hard to deal with, however, so be careful of spraying too much. The best way to accomplish this challenge is to play with SMGs until you know them. Learn to tell how many shots it will take to kill a person and shoot just that many. Too many and you miss, too few and you die and have to start over.
Dictator - Fire an entire LMG magazine into enemies without missing. Worth 2,000 EXP. Unlocks the Dictator title and the FMJ emblem. This is by far the most difficult of the full-clip challenges. LMGs have a LOT of ammo and a LOT of kick; this makes them challenging to kill one person without missing, let alone enough to empty your clip. Use the AUG! It has far less ammo than the others, and reloads like an assault rifle. Use a foregrip or a silencer if you need to, so you can have more accuracy or less of a chance of being found. The biggest challenge with this challenge is not dying halfway through. Take your time.
Perfectionist - Fire an entire sniper magazine into enemies without missing. Worth 2,000 EXP. Unlocks the Perfectionist title and the sniper scope emblem. This is by far the easiest of the full-clip challenges. Sniper rifles are meant to be highly accurate and have low clips, especially the Intervention. Take your time and snipe for a while, and this challenge will fall into your lap.

Precision Challenges - Level 31, Part 1
As above, the second set of precision challenges requires further accuracy. This time it comes in the form of multi-kills for your various explosives, as well as a few miscellaneous challenges that don't fit anywhere else, and that involve being accurate and lucky with your bullets. This set of challenges is unlocked at level 31.
Multi-RPG I, II, and III - Kill 2+ players with one AT-4 or RPG-7 round, 5, 25, and 50 times. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Big Bada Boom title, and challenge II unlocks the Kill for Good title. Challenge III unlocks the hyena emblem. This challenge is relatively easy to get early using the AT-4. You don't have to wait for the RPG-7 to do it. Play game modes like Domination and wait around contested points, usually point B. When multiple players gather, fire away. Should be easy.
Clay More I, II, and III - Kill 2+ players with one Claymore, 5, 25, and 50 times. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Parting Gift title. Challenge II unlocks the Ambush title. Challenge III unlocks the Rhino emblem. Somewhat more challenging than the Multi-RPG challenge, this one requires that several opponents try to pass your claymore at the same time and fail. Try using Danger Close for a larger explosion. Place your claymores in high-traffic areas, instead of using them to defend your camping point.
Multi-Frag I, II, and III - Kill 2+ players with one Frag grenade, 5, 25, and 50 times. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Booyah! title. Challenge II unlocks the Pin Puller title. Challenge III unlocks the Bear emblem. Frag grenades work best when cooked, so hold the timer a few seconds and throw so it explodes where you want it. Like the Multi-RPG challenges, try to find domination points and high-traffic areas. Danger Close can help as well.
Multi-C4 I, II, and III - Kill 2+ players with one C-4 Pack, 5, 25, and 50 times. Worth 2,000, 5,000, and 10,000 EXP respectively. Challenge I unlocks the Boom Boom title. Challenge II unlocks the The Anarchist title. Challenge III unlocks the sugar glider emblem. Use your C4 like you would a Claymore, and watch the point you place it. Alternatively, use a riot shield and throw your C4 into the middle of a crowd, detonating immediately. Danger Close helps. If you lay a C4 on a domination point you're running the risk of players throwing grenades and destroying it, which happens fairly often.
Collateral Damage - Kill 2 or more players with one sniper rifle bullet. Worth 2,000 EXP. Unlocks the 1bullet2kills title and the black skull emblem. Sniping frequently is the best way to do this, and chances are when you finally accomplish it, it'll be luck. Sniping in high-traffic areas or at the very start of a match can help. Using the narrow sniping corridor in Highrise from one end of the map to the other at the very start is a good place to try. Height isn't your friend for this challenge; the higher you are, the closer two enemies have to be to snipe them at the same time.
- slide 12 of 21

Precision Challenges - Level 31, Part 2
Flawless - Play an entire match without dying. Worth 2,000 EXP. Unlocks the Highlander title and the eagle emblem. For this challenge, ignore getting kills. Do everything you can to survive. Find an out of the way place, using Cold-Blooded and Ninja to stay invisible, and hide. Use a sniper rifle so you have a Ghillie Suit and go prone in a low-traffic corner, like the far end of Estate, some corner of Wasteland, or an out of the way spot in Karachi. Your teammates may hate you for doing nothing, but you'll get your challenge done.
Fearless - Kill 10 enemies in a single match without dying. Worth 2,000 EXP. Unlocks the Streaker title. Two ways to get this challenge done. The first is to camp, camp hard, and luck out not getting killed. The second is to run and gun, trying to kill everyone before they kill you. Neither method is foolproof, and you're going to die at seven, eight, nine kills. Keep trying, and eventually you'll get a good match and accomplish the challenge.
Group Hug - Kill multiple enemies with a single Semtex stuck to one of them. Worth 2,000 EXP. Unlocks the Enemy with Benefits title and the target patch emblem. Simply; use the Semtex. Try to throw it in high-traffic areas and around domination points where players tend to congregate. Eventually you'll kill more than one person with a stuck grenade, and finish the challenge.
NBK - Kill 3 enemies with Longshots in one life. Worth 2,000 EXP. Unlocks the NBK title. This is easiest done by sniping, though any gun can get you a long shot. The trick is to not die between the long shots. Maps like Derail, Wasteland, and the long roads in Invasion and Favela can get you a good chance.
All Pro - Headshot two enemies with one bullet. Worth 2,000 EXP. Unlocks the All Pro title and the crosshairs and binocular emblems. The best way to complete this challenge is to use a shotgun. The Spas-12 with a foregrip and steady aim is a killing machine. This is another challenge you can't really set up for yourself, you just have to luck into two enemies in a line where your shot can get them both. Any gun can complete this challenge, shotguns simply have a wider spray with enough stopping power to take down multiple players.
Airborne - Get a two killstreak with bullets while in midair. Worth 2,000 EXP. Unlocks the Hard Target title and the stomping boot emblem. Jump and shoot. Use a high damage weapon, like the Scar, or guns that spray a lot of bullets, like the Vector. Jumping off balconies gives you a longer time to shoot while falling, but you run the risk of dying, breaking your killstreak. Run Commando Pro to negate that risk.

Finishing Move Challenges - Level 35
Finishing Move challenges are exactly like they sound. These challenges all involve getting a game-winning kill cam doing something specific. This means two things: First, you have to actually win the game. A game that ends through time or through an objective being completed doesn't count. Therefore you can only complete these challenges in Free For All, Ground War's Team Deathmatch, and regular team deathmatch. Of course, the hardcore mode of TDM works as well. Meanwhile game types such as Sabotage, Headquarters, and Domination don't work. This set of challenges is unlocked at level 35.
Droppin Crates - Game-winning Killcam with a crate dropped on an enemy. Worth 2,500 EXP. Unlocks the Droppin' Crates title and the snake eyes dice emblem. This is perhaps the hardest of all the killcam challenges. It's hard to even kill a player with a crate, let alone time it perfectly. Save your care packages, sentry guns, and emergency airdrops. Use them on domination points or in high-traffic areas, and don't worry about getting the crates yourself. The point is to throw them in enemy-infested territory to attempt to crush one of them. If you find someone prone and completely unaware of you, try throwing the grenade behind them, but only attempt this near the end of the match. Chances are if you complete this challenge, it'll be pure luck.
Absentee Killer- Game-winning Killcam with a Sentry Gun. Worth 2,500 EXP. Unlocks the Absentee Killer title and the gatling gun emblem. This, like most of the rest of the killcam challenges, comes with the same advice. Use the sentry gun near the end of the match, set it up in a high traffic area, and hope you get the final kill.
Drone Killer- Game-winning Killcam with a Predator Missile. Worth 2,500 EXP. Unlocks the Dronekiller title and the missile emblem. Save your predators for the end of a match, and try to time it so you get the final kill or two with it. No better advice can be given.
Finishing Touch- Game-winning Killcam with a Precision Airstrike. Worth 2,500 EXP. Unlocks the Finishing Touch title and the precision airstrike emblem. Use your precision airstrikes when there are only a few kills left in the match, and you have the best shot at getting the final kill. Other than that, it's simply the luck of the timing.
True Liar- Game-winning Killcam with a Harrier. Worth 2,500 EXP. Unlocks the True Liar title and the harrier emblem. Harriers can be called in a little earlier than other killstreaks to try for the final killcam, simply because they float around shooting for a while. Call them in near the end of the match and hope you get the final kill.
OG- Game-winning Killcam with an Attack Helicopter. Worth 2,500 EXP. Unlocks the OG title and the helicopter helmet emblem. Attack Helicopters and Pave Lows operate essentially the same, so call them in at the end of a match and hope they get the final kill. Since you can't target them, you don't really have much control over when they kill, so all you can do is call them in and hope.
Transformer- Game-winning Killcam with a Pave Low. Worth 2,500 EXP. Unlocks the Transformer title and the pave low emblem. See the description for OG for advice using Pave Lows.
Techno Killer- Game-winning Killcam with a Stealth Bomber. Worth 2,500 EXP. Unlocks the Techno Killer title and the stealth bomber emblem. Like precision airstrikes, Stealth Bombers should be called in near the end of the match, hoping to get the final few kills.

Finishing Move Challenges - Level 37
Like the above section, these also involve the game-winning killcam. These are slightly harder, but not by much. This set of challenges unlock at level 37.
Hi Def - Game-winning Killcam with a Chopper Gunner. Worth 2,500 EXP. Unlocks the Hi Def title and the night vision nuke emblem. Like the other killcam challenges, you just have to use the killstreak at the end of the match and hope you get the final kills. This is easier with the Chopper Gunner as you can likely get several kills instead of just one or two.
Death from Above- Game-winning Killcam with an AC-130. Worth 2,500 EXP. Unlocks the Death From Above title and the AC130 flares emblem. Like the Hi Def challenge, the AC-130 is good to get a number of kills at the end of a match and hopefully get you the final kill.
Unbelievable- Game-winning Killcam with a Throwing Knife. Worth 2,500 EXP. Unlocks the Unbelievable title and the throwing knife emblem. Throwing knifes are hard to aim accurately and when you're racing against time, it'll be harder. If you're lucky, near the end of the match you can find an oblivious camper and wait behind them. When you see the second-to-last kill, throw your knife.
Owned- Game-winning Killcam with a Riot Shield's shield bash. Worth 2,500 EXP. Unlocks the owned. title and the Jugs emblem. Same with the Unbelievable title, try to find someone and wait until the match is about to end to kill them. Hardcore mode makes a shield bash kill in one hit instead of two, but you're less likely to find someone who won't notice you're behind them.
Stick Man- Game-winning Killcam with a stuck semtex grenade. Worth 2,500 EXP. Unlocks the Stickman title and the Stryker tank emblem. Use the Semtex all the time and your chances of this greatly increase. If you need to, find an oblivious player and wait until the game is almost over to throw the grenade at their back.
Last Resort- Game-winning Killcam while in Last Stand or Final Stand. Worth 2,500 EXP. Unlocks the Last Resort title and the motorcycle emblem. Unlike the other killcam challenges, this one involves being killed yourself. In this case the only thing you can do to ensure your chances, is to charge into the enemy territory repeatedly and kill as many as you can while on last stand or final stand. Final stand is probably better, because you can use your primary weapon, and you have a longer time to lay.

Humiliation Challenges - Level 41
Humiliation Challenges occur in any game type, on any map. Most of them involve killing an opponent in some way that should make them feel bad about themselves. Throwing their own grenades back at them, for example, or killing an enemy, picking up his weapon, and killing him with his own weapon. These challenges unlock at level 41.
Hot Potato I and II - Kill 5 and 10 enemies with thrown back grenades. Both are worth 5,000 EXP. Challenge I unlocks the Tag! You're it! title, and challenge II unlocks the combat vest emblem. Unfortunately, not many players these days use frag grenades when Semtex are more powerful, explode sooner, and are easier to use. Fortunately, if you throw a frag grenade at a wall and pick it up to throw again, this counts. Do not cook a grenade to do this, as you'll probably kill yourself.
Car Bomb I and II - Kill 5 and 10 enemies by making cars explode. Worth 3,000 and 5,000 EXP respectively. Challenge I unlocks the Boilermaker title and challenge II unlocks the exploding car emblem. Maps like Favela are good for this challenge due to the number of cars littered around. In Favela if you spawn at the bottom of the hill, send a grenade up to the car at the top of the hill; most of the time a player running around the corner will be caught in the blast.
Backstabber - Stab an enemy in the back with your knife. Worth 3,000 EXP. Unlocks the Backstabber title and the shuriken emblem. This one is pretty easy; find someone camping and stab them in the back, or circle around someone shooting at you and do the same. More likely than not you'll have done this several times over by the time you even unlock the challenge.
Slow But Sure - Kill an enemy while stunned. Worth 3,000 EXP. Unlocks the Stun Gun title and the Snowmobile emblem. If an enemy stuns you, try to predict where they'll be and shoot at them when they enter. Most times enemies stun you while you're camping, so you know what entrance they'll be coming in. The key is to already be pointing at the door when they enter; if you're not, you can't turn fast enough. Alternatively, find a camper and throw a stun such that it hits yourself while you're already pointed at them.
Misery Loves Company - Cook a grenade and kill yourself and one enemy when it explodes in your hand. Worth 3,000 EXP. Unlocks the <3 title and the chicken emblem. The easiest way to do this is the method for many of these challenges; find someone who doesn't know you're there and cook a grenade behind their head. Alternatively you can cook a grenade and run into a mob, but you run the rist of getting gunned down before the grenade explodes. On the plus side, this acts as a make-shift martyrdom and may net you kills if you fail.
Ouch - Using the grenade laucher attachment, shoot an enemy and kill them with the direct impact of the grenade. Worth 3,000 EXP. Unlocks the Noob Tuber title and the direct impact emblem. This is a relatively easy challenge to complete. Run One Man Army to refresh your grenades when you run out, and don't camp. Don't switch weapons to fight at close range; instead shoot your grenades right into the player running at you. If you miss, you probably won't live for a second shot, but if you hit, you'll probably get the direct impact at close range.
Rival - Kill the same enemy 5 times in a single match. Worth 3,000 EXP. Unlocks the Rival title and the TF141 emblem. There's no sure-fire way to make sure you get this challenge completed. Your best chance is to kill as many players as you can and hope one of them gets in the way of your bullets more times than the rest. You could also use SitRep to find enemy tactical insertions. If a player is using a tac insert, chances are they're nearby; kill them, let them spawn, and kill them again. Then wait for them to put up another insertion somewhere else, or to come right back to their previous camping spot.
Cruelty - Kill an enemy, pick up their weapon, and kill them with their own weapon. Worth 3,000 EXP. Unlocks the OMFG title and the cow abduction emblem. This is not a challenge you're likely to accomplish accidentally; most players don't pick up weapons as a matter of course. To get this challenge, kill an enemy and pick up their weapon, and proceed to rampage with their weapon until you kill them. This is easiest if you pick up a dangerous weapon, like the ACR, or akimbo shotguns, or anything you like to use and are used to. For a more methodical approach, kill a sniper and snipe them when they find a new camping spot.

Humiliation Challenges - Level 43
As a final section for this article, the rest of the humiliation challenges. These are slightly harder than the first batch of challenges, but not by too much. They require such things as hitting an enemy with a few bullets and then finishing them with a direct grenade impact, or killing every member of the enemy team without dying in between. This set of challenges unlocks at level 43.
Think Fast - Wound an enemy and finish them with a direct impact from a frag grenade. Worth 3,000 EXP. Unlocks the Think Fast title and the League Grenade emblem. This and the other think fast challenges are difficult, however, they're easier in Hardcore mode. Grenade impacts don't do a lot of damage, so the less HP a player has, the better. The trick to hardcore mode, though, is it's really easy for a bullet to kill a player. This makes finishing them with the grenade harder. Try to aim for the legs with your bullets, and throw the grenade immediately. Prone campers make this much easier.
Think Fast Stun - Wound an enemy and finish them with a direct impact from a stun grenade. Worth 3,000 EXP. Unlocks the Concussive Barrage title and the stop sign emblem. See the Think Fast challenge for tips.
Think Fast Flash - Wound and enemy and finish them with a direct impact from a flash grenade. Worth 3,000 EXP. Unlocks the Lights Out title and the light bulb emblem. See the Think Fast challenge for tips.
Return To Sender - Kill an enemy by shooting their own explosive. Worth 3,000 EXP. Unlocks the Backfire title and the biohazard emblem. SitRep helps you know where enemy explosives are. Ideally you'll catch a player in the act of planting a claymore and can shoot it immediately. Claymores are the only explosives you're likely to get this challenge completed with. C4 is thrown too far usually, or planted and left. Just shoot every claymore and C4 you come across and eventually you'll complete the challenge.
Blindfire - Kill an enemy while blinded by a flashbang. Worth 3,000 EXP. Unlocks the Blindfire title and the Xray skull emblem. Just like the Slow But Sure challenge, try to predict where the enemy that flashed you will be sitting. Alternatively, you can flash yourself and kill a camper. Even being slightly flashed, rather than completely blind, will count.
Hard Landing - Kill an enemy that is in midair. Worth 3,000 EXP. Unlocks the Skeet Shooter title and the Rocket Tank emblem. There's no real method to compelting this challenge. Try to kill enemies as they jump from balconies to ambush players. The sniper hill on Afghan and the roof and balcony in Invasion are places players like to leap from, so watch for easy kills.
Extreme Cruelty - Kill every member of the enemy team without dying in between. Worth 3,000 EXP. Unlocks the All Your Base title and the necklace of ears emblem. The trick to completing this challenge, usually, is to use explosives and Danger Close. Domination is a good game mode where you can catch several players at once and then hunt down the others. Try not to die and you should be fine.
Tango Down - Kill every member of the enemy team. Worth 3,000 EXP. Unlocks the Devestator title and the shadow company emblem. Like Extreme Cruelty, but it doesn't care about your deaths. Chances are, unless one player has a very good hiding spot, you'll accomplish this easily.
Counter MVP - Kill the #1 player on the enemy team ten times in a single match. Worth 3,000 EXP. Unlocks the MVP assassin title and the porter justice emblem. This challenge is pretty difficult given that ten of your kills must come from the best player on the enemy team. If the best player on the enemy team changes, you can't keep hunting down the same player. Given the drastically different situations and play styles, it's best just to play, and hope you get this eventually.
