Medal and Dirt

U.S. Air Force Master Sgt. Jason Tilley, 20th Equipment Maintenance Squadron, bites his medal after completing an Ultimate Marine Corps Mud Run in Columbia, S.C., April 30, 2016. The 6.2 mile run that consisted of 20 obstacles, was created by a retired Marine Corps Drill Instructor who hoped the run would give people who havnt joined the military a look into what it takes to complete boot camp.
