A Flash Pistol in Ender's Game (Film)

A Flash Pistol, also known as a Dao (Vietnamese for "knife"), was a laser weapon used in zero gravity competitions and training in the Battle Rooms. A laser shot from the pistol would immobilize any contacted region on an opponent's flash suit, effectively immobilizing them. It had a trigger, a red button (for a tight, laser-like beam) and a white button (for large-area illumination) on its end which were easily accessible to the thumb, and several others along the bottom of the shaft that were essentially inaccessible except when using two hands.[1][2]
