As everyone is about to say/have said. Commando. In all honesty Commando wouldn't be all that bad if it weren't for tac knifers.
But Danger Close as well; tubing would actually take skill!
Commando is the only perk that I really dislike. Personally I'd like to see the knife replaced with a 2 hit weapon melee because it seems like every close encounter turns into a knife fight.
