In Metal Gear Solid 4, the all-female haven troops cannot be knocked unconscious by grabbing their crotch after a body search (as it turns into a grope). If Snake tries this, the soldier will start yelling "Pervert!", "You idiot!", "If you don't cut that out...", or "You men are all the same!" They will soon retaliate with an incapacitating kick. That said, there's a slight chance they will say, "Hey, you're pretty good at that."
