Hundreds of Special Tactics (ST) Airmen and Special Warfare trainees gathered early morning to begin an 830-mile ruck march across five states in tribute to U.S. Air Force Staff Sgt. Dylan J. Elchin, along with 19 other ST Airmen, who have been killed in action since 9/11, Feb. 22, 2019, at Joint Base San Antonio-Lackland Medina Annex. The ruck march is projected to average about 12 miles per leg, alternating between the ten teams of two throughout the day ending at Hurlburt Field, Fla., at 1:00 p.m. on Mar. 4, 2019. The 830-miles event will take over 11 days averaging 70 miles each day. (U.S. Air Force photo by Andrew Patterson)
