U.S. Air Force combat controllers march more than 800 miles from Lackland Air Force Base, Texas to Hurlburt Field, Florida, passing through downtown San Antonio. The march is in memory of 12 special tactics Airmen who died in combat in Iraq and Afghanistan. The march starts at Lackland where combat controller training starts. It ends 10 days and five states later at Hurlburt Field where Airmen become combat controllers. (U.S. Air Force photo/Airman 1st Class Brian McGloin)
