[25mm GATLING GUN vs. COLT 1877 BULLDOG GATLING GUN AT ABERDEEN PROVING GROUND]

Description: Raw, silent footage from the Aberdeen Proving Ground, showing a demonstration of what appears to be a 5-barrel General Dynamics GAU-12/U Equalizer compared to what might be a 5-barrel Colt 1877 Bulldog Gatling Gun with Carriage.. The GAU-12 is a five-barrel 25 mm Gatling-type rotary cannon used by the United States, Italy and Spain, which mount the weapon in their attack jets such as the AV-8B Harrier II, airborne gunships such as the Lockheed AC-130, and land-based fighting vehicles. A lighter four-barrel version, designated GAU-22/A, is mounted on F-35 Lightning II fighter jets.
