An Airman from the 307th Logistics Readiness Squadron loads an M4 Carbine magazine prior to qualifying with the weapon at Barksdale Air Force Base, La., Jan. 30, 2018. Dozens of Airmen took part in the exercise as part of their regular military training. Before firing the weapon, the Airmen received classroom instruction on weapons safety. They also had to take the weapon apart and reassemble it before being allowed to fire. (U.S. Air Force photo by Master Sgt. Ted Daigle/released)
