i dunno if this should go in glitches and tricks or here so I'll post the same thing I posted in glitches/tricks as I did here.

If you are going for the MOAB, your killstreaks don't normally count towards the 25 kills. However on the map Bakaara or whatever the one with the downed heli with the chaingun turret, you can get a juggernaut (the one with the riot shield OR the one with the M60 M60 is preferred) and use the machinegun turret, normally getting kills with the M60 as the juggernaut doesn't count at all but the machinegun turret will count towards your 25 killstreak. because of your juggernaut armor you're pretty much unstoppable and it's best on domination and such because it doesn't spawn their team behind you. you can get instakilled by a rocket launcher but so far nobody has done that to me.

I use UAV-Attack Heli-Juggernaut on the assault loadout, the UAV is really helpful for getting the helicopter and the helicopter is really helpful for getting the juggernaut. drop that bitch down and camp the hell out of the turret. First game I thought of this I got the MOAB easy and I've gotten one every time I've gotten juggernaut on that map since
