A Keesler Air Force Base firefighter uses a hand-held hose to extinguish a fire inside a mock C-123 Provider training device during an aircraft rescue fire fighting training on Keesler AFB, Miss., June 4, 2019. The joint agency training allowed the Keesler Fire Department, Gulfport Combat Readiness Training Center Fire Department, Stennis Airport Fire Department and the U.S. Naval Air Station Pensacola Gulf Coast Fire Rescue to meet the semi-annual training requirement to practice aircraft rescue and live fire training evolutions.
