Special Tactics Airmen greet a local elementary school class in Fort Walton Beach, Fla., Oct. 13, 2015. The team of 20 Special Tactics Airmen started at 2 a.m. Oct. 4, from Joint Base San Antonio-Lackland, Texas, and marched 812 miles through five states to meet with the gold star families and end the memorial march with a ceremony on Hurlburt Field. Each two-man team walked approximately 90 miles during the 10-day trek while carrying a 50-pound rucksack and a commemorative baton engraved with a fallen Special Tactics Airman's name. The memorial march is only held when a Special Tactics operator is killed in action that year, but honors all 19 Special Tactics pararescuemen and combat controllers who have been killed in action since 2001.
