Air Force members practiced dismantling and reassembling the M240B medium weight machine gun during a training course at Joint Base San Antonio-Lackland Feb. 9.

The course is two weeks long, culminating in three days where students familiarize themselves with weapons by live firing in multiple conditions, and is designed to ready students for mission demands on day one of assignment at their new base where this training is not available.

The M240B machine gun is a belt-fed, air-cooled, gas-operated, fully automatic machine gun that fires from the open bolt position.
