they wouldn't have gatling guns, those are typically on aircraft. at most they'd have M203 grenades, maybe AT4s or LAWs, M16/M4s, M249 SAWs, and possibly M240B. nless they grabbed a .50 off of a humvee, the heaviest they would have would be the 7.62 from the 240. they might have 40 mm grenades, but it takes time t learn to use those properly since those are indirect fire weapons. i doubt they would have any kind of rocket system since that wouldn't exactly be necessary for suppressing riots. if they're toting MP5s (which for some reason i feel they are (maybe it's the wat van)) then the weapons they have most likely came from the police station, in which case they would have MP5s (9mm), M4s (5.56mm), Shotguns, smoke and flash grenades... that's about all i'm getting on this one. maybe i'll think of more later. the easiest weapons to put in the hands of anyone and get them fighting woul be the M16/M4, MP5, and shotgun. of course if they made their first stop the maller armory i'm sure they'd find AKs (the most prolific rifle in the world) and those are about as plug and play as you can get.
