Machine gun training - A man standing next to a machine gun

William Treadway, training support specialist with the Training Support Center in Wiesbaden, works with the MK-19 40 mm grenade machine gun. A self-powered, air-cooled, belt-fed, blowback-operated weapon designed to deliver decisive firepower against enemy personnel and lightly armored vehicles. Mr. Treadway prepares it for soldiers to use with the Engagement Skills Trainer (EST). The TSC-Wiesbaden Simulators section is located in Building 1638, Clay Kaserne, at Wiesbaden, Germany.
