Apparently they can just disappear. They know where everyone is. They can see through camouflage (probably having to do with differences in infrared radiation). Nobody's punches (even Scott's and Theo's) affect them at all.

I think the only way they can beat them is if they hide their super steroids. :P It seems like they need injections to keep them stronger. Maybe they are trying to find a better medicine for themselves to stay alive, or to keep the guy in the tank alive.
