Air Force Master Sgt. Maria Teresa Pineda carries a huge sandbag with a team of special operations recruiters at the 350th Battlefield Airmen Training Squadron facility at Joint Base San Antonio, Texas, June 28, 2018. The ruck march and sand bag carry began at 2 a.m. and is one of the many challenges presented by the squadron to give the recruiters knowledge of what their recruits endure. DoD photo by EJ Hersom
