riot shields are hilarious, i was playing with this other clan right, the guy on the other team just gets jumped by like 3 guys, including me, 2 of them are trying to ram him from the side, all with the riot shields, the guy moves and i pop him with my machine pistol, everyone was just laughing it up.
i hate the riot shield, it doesnt protect you very long, you have to crouch to stay alive, and constantly be in fear of someone shooting your book, or overhead
