The pictures first show a Guardian Angel team from the 83rd Expeditionary Rescue Squadron preparing for the high altitude low opening jump next to a C-130J Super Hercules.
High altitude low opening jumps, or HALOs, are when parachutists jump from a high altitude and open their chute at a low altitude, a technique used by the military that minimizes risk to the troops from enemy fire.
PJ's have "conducted over 12,000 lifesaving, combat rescue missions since September 11th, 2001," according to the Air Force.
