Body Hardening
Staff Sgt. Paul Amasol, 56th Communications Squadron airfield systems technician, punches Staff Sgt. Abel Telles, 56th Logistics Readiness Squadron fuels specialist, in his stomach during a military combative course held at the Combat PT Center at Luke Air Force Base, Ariz., April 5. This session of the training course is called "body hardening" in which one allows the body to adjust to getting hit. (U.S. Air Force photo by Airman 1st Class Ronifel Yasay)
