skills needed

[mogar]

hi, i recently needed to scrap a bunch of skills that i realized were useless in a symmetrical map. what i need are three special skills that a commando would have, and one skill a sniper would have. so far for the commando i have throwing knife. for the sniper i have head shot, stealth and claymores. my brain has run dry and i cant think of anything else XD. any suggestions are welcome.
