(I always put Sitrep on classes than have a silenced gun, because I use those classes to rush and flank, and I dont want to be killed by claymores)

This is the final strategy if you are really struggling.

Make 3 classes with One Man Army.

One class will have Stopping Power as the 2nd perk, the other class will have Hardline, and the last class with have Coldblooded. You may also make an additional class with Danger Close Pro to increase the effectiveness of your killstreaks (especially useful if you use the chopper gunner). Start the game with the Stopping Power class, then when you get 5 kills, switch to the Hardline class and get your Harriers. Get your AC130 then if you still need more kills switch back to the Stopping Power class, then switch back to the Hardline class when you are on a 23 killstreak. (Warning: Use good judgement will switching classes, if you are not careful you will get yourself killed. Only switch classes when you are absolutely sure you wont be killed.) Also, switch to the Coldblooded class of the enemy gets a UAV or air support.

Note: I strongly recommend using the AC130 and playing ground war. If you use the chopper gunner, it will get shot down very fast.

If you play Team Death Match, go ahead and use the Chopper Gunner, there seem to be more noobs in TDM and the AC130 isn't as good in TDM. Also, ground war is annoying because there are so many OMA noobtubers.

Put it in the class with a riot shield because u have to be able to get a 25 kill streak
