Staff Sgt. Gregory Mazzone, 379th Expeditionary Civil Engineer Squadron firefighter, and Tech. Sgt. Gabriel Boulware, 379th ECES crew chief, repack the 1 ¾-inch hand line from Engine 21 June 24, 2016, at Al Udeid Air Base, Qatar. Repacking a hand line requires certain hose lines loaded in specific ways for different situations. Ensuring the hose is placed back on the Engine 21 correctly is critical to its rapid deployment at the next emergency where it is needed. (U.S. Air Force photo/Senior Airman Janelle Patiño/Released)
