Rampage: President DownGoofs
When Bill sets up his automated machine gun, he sets it with the barrel aimed down the hill, and leans a camouflaged board against the muzzle to conceal it from the river. But when he takes remote control of it the barrel is pointed up into the trees and he has to take a few seconds to depress the gun so it can fire down the hill.
During the opening scene of a raid on the cabin, Bill is seen with an AT4 rocket launcher. These rocket launchers have a color coded band on them to indicate the use of that particular launcher. The AT4 shown in the cabin has a solid yellow band, indicating an inert launcher used solely for instructional and training purposes; it contains no explosives of any sort. An actual active HE (High Explosive) AT4 would be coded with either a solid black band or a black and yellow band.
