U.S. Army Staff Sgt. Denneit Disla, right, 98th Reserve Division drill sergeant, instructs a Soldier how to fire a M203 Grenade Launcher during an round-robin event as part of the annual Drill Sergeant of the Year competition, June 26, 2012, at Fort Eustis, Va. During the event competitors we’re tested in their knowledge on how to disassemble, reassemble, and perform function checks on a variety of weapons, as well as their ability to walk someone through the proper steps of handling the weapons.
