Students in the pararescue indoctrination course at the Lackland Training Annex recover after completing a 40-meter underwater swim June 17. The 10-week course trains future PJs through intense physical and mental training. Only the best of the best will make it - the drop-out rate during the initial 10-week pararescue indoctrination course is typically sixty to seventy percent. (U.S. Air Force photo/Robbin Cresswell)
