Marines from C Company, 2nd Tank Battalion, Regimental Combat Team 5 let loose with the M-1A1 Main Battle Tank's 120 mm main gun. Tankers recently fired on Camp Fallujah's Eagle Range to zero all their weapons, including lanyard firing some tanks for their first shot. Tankers said all the maintenance and care that goes into keeping the tank rolling is worth the effort when they get the chance to fire the Marine Corps' largest direct-fire weapon.
