See my topic of "REQ: Equipment..." - I wrote about the same things. It seems to become harsh need: to have a way to fight with fists and, probable, legs: you may deblock your way without killing a civilian (or paralysing him with yourself)
Or I would be glad to see stunning grenades like was in UFO:Apocalypse (they little affects aliens, but very usable to remove annoying civil without killing them)
