3+2+1= Check 6
                Two U.S. Airmen demonstrate their newly learned skills on weapons retention during Check 6 training May 25, 2015, at Bagram Air Field, Afghanistan. Check 6 is a mandatory program for all BAF Airmen and includes training on how to react and respond to an active shooter/insider threat as well as how to perform as a team in the event a hostile situation should occur at the base.
