U.S. Air Force Tech. Sgt. Ismael Fierro, a Combat Arms Training and Maintenance instructor with the 169th Security Forces Squadron at McEntire Joint National Guard Base, South Carolina Air National Guard, monitors Airmen during M-9 pistol qualifications at the base shooting range, April 6, 2018. Swamp Fox Airmen continue to hone routine skills to meet combatant command requirements. The muscle memory that is formed by using this equipment multiple times allows Airmen the ability to focus their attention on completing the mission under austere conditions.
