Ruck March
Members of the Hurlburt Field motorcycle group, Sentinels of Freedom, led 18 Special Tactics Airmen, family and co-workers, through the main gate as they complete an 812-mile memorial march from Lackland Air Force Base, Texas, to Hurlburt Field, Fla. Special Tactics Airmen perform this march each year that a Special Tactics Airman loses his life in defense of his country. (U.S. Air Force photo/Master Sgt. Steven Pearsall) (RELEASED)
