Oh, and duck, the armor suits aren't like the in-game suits. They've got a good resistance to small arms fire, to the point where they'd actually be able to take a dozen or so hits before getting something injured, like a laceration or broken bone. But, they do have enhanced reflexes and the like. Not super-duper, but better than humans that aren't taking martial arts classes for fun. And, obviously, connected to the service rifles the soldiers carry, and a special side-arm, so that they can see where they're pointing with a transparent laser-light-ish-thingy. Like, aiming without having to bring your rifle up. And, nightvision, infrared, etc.

But they're hard to make, so they're rare. See one, run away is your best bet, unless you're in close with an automatic shotgun, you're out of range with a heavy weapon, like a snuperrifle, or you have a couple spare grenades to toss.

But [i]they might toss the grenades back![/i]
That made the old CoD's so fun ^.^
