The gametype you need to play all the time is Kill Confirmed. Whenever you get the Recon Drone make sure to tag as many people as you can because you get so much EXP from that. The reason for the Shotgun attachment on the CM901 is because the gun is high powered and with the shotgun attachment it makes it shoot 750 shots per minute which is better than the standard 666 spm. Also, whenever the enemy team calls in air support always shoot it down with the stinger because when you do this you are 1 point closer to your point streak. Next step: Thread Stickied

No, it only works with the CM901 and you can also use the Grenade Launcher and it does the same.

i disagree. you don't get a lot more xp in kill confirmed. In kill confirmed you have to have your kills confirmed to get kills and you have to actually deny kills without dying. Plus the score limit is 65 whereas tdm its 7500. You might have a game here and there where you earn more kills but confirming kills/denying kills makes you more likely to die which will end your k.s. In regular tdm there is no "confirming", you get a kill you get the +100 guaranteed. Not a +50 and a maybe +50. Tdm is the best gamemode to constantly gain exp but to each his own. Plus i find tdm to be less campy because the objective is to kill and the spawns are pretty random so camping will rarely get you a high k.s.

Another thing you can add is recon drone + ground war. In ground war it is a BEAST. My friend ended up getting 40 assists in one match which is ridiculous. Plus i believe(have not tried it) using hardline pro along with recon drone increases your k.s. after you get the tagged assits so you can end up getting your high k.s. and gaining a crapload of xp without even getting kills haha.

They fixed the underbarrel attachment glitch with the CM901 to increase the fire rate; just like how they fixed the extra pellets that would come out of a shotgun with extended mags on it. Other then that; kill confirmed gives 50+xp a kill so taggin enemies woiuldn't really give you much extra.
