Jermaine King, 35 SFS NCO in charge combat arms, perform a weapons check after firing the M240B machine gun during a weapons firing demonstration for students from Edgren High School's Junior Reserve Officer Training Corps at the small arms range at Misawa Air Base, Japan, May 4, 2012. Weapons checks are performed to ensure the weapon is clear of all ammunition and links. The purpose of the visit was to help the students get a better understanding of some of the training their parents have to do before deploying.
