The elite Combat Rescue members of the U.S. Air Force, Pararescuemen, or PJs (Pararescue Jumpers), have one mission: rescue American or allied forces in extreme danger. Whether their targets are shot down or isolated behind enemy lines, surrounded, engaged, wounded or captured by the enemy, PJs will do whatever is necessary to bring those in peril home. For the first time in their history, the PJs allow camera crews to cover their missions in Afghanistan. Experience the action and the drama from the front lines first-hand as National Geographic embeds with the Expeditionary Rescue Squadron, and uncovers the lives of these elite airmen.
