Airman 1st Class Lawrence Gress, an explosive ordinance disposal journeyman with the 1st Special Operations Civil Engineer Squadron, checks the jaw assembly of an MK1 rocket wrench during EOD tool training at Hurlburt Field, Fla., Mar. 6, 2017. If the rocket wrench is not straight, it may not properly remove the fuse and could cause damage to the tool. (U.S. Air Force photo by Airman 1st Class Joseph Pick)
