Davis-Monthan Air Force Fire Fighters, assigned to the 355th Civil Engineer Squadron, participate in a live-fire exercise, Oct. 21, using the P-19 Fire Fighting Truck, which uses technology that reduces the amount of water and foam needed to extinguish a fire. Currently only a number of P-19 are in uses in the Air Force, but the Air Force plans to purchase more P-19 Fire Fighting trucks in the future. (U.S. Air Force photo/TSgt. Kerry Jackson)
