For my play style, hes got this whole "Rush" thing wrong.

Generally you would use a silenced primary weapon, along with the UAV CUAV/Care package then the predator. Also, I wouldn't use Semtex, I'd use either the: Claymore or Bouncing Betty.
And I think I'll be using the MP7 when I unlock that, from what I've seen, it looks beast.

My setup:

Primary - MP7 w/ Silencer.
Secondary - Not too sure on this one...
Proficiency - Range or Melee (faster knife)
Tactical - Portable Radar or Concussion grenades.
Equipment - Claymore or Bouncing Betty (Both are pretty similar)
Perk 1 - Extreme Conditioning
Perk 2 - 1 rush class with Blast Shield and another Assassin
Perk 3 - 1 rush class with Dead Silence and another with Stalker
Killstreaks - (3) UAV (4) Care Package (5) Predator Missile.

What are you gonna use?

Primary: G36C with red dot
Secondary: deagle
Proficiency: less kick
Tactical: flash bang
Equipment: frag
Perk 1: dunno yet
Perk 2: dunno yet
Perk 3: dunno yet
Killstreaks: that little support helicopter, juggernaut and advanced uav

Edit: oh sorry, thought it was a post your class here thread
