The 920th Rescue Wing, based out of Patrick Air Force Base, serves as an Air Force Reserve Command combat-search-and-rescue unit. They are responsible for a variety of demanding missions and ready to deploy at a moments notice, trained to perform some of the most highly specialized operations in the Air Force. They've been the primary rescue force serving as “guardians of the astronauts” for 50 years, providing contingency response for a variety of emergencies that could potentially come up during a Space Shuttle launch or landing. These airmen and their elite team of Pararescuemen, known as PJ’s, are among the most highly trained emergency trauma specialists in the U.S. military, capable of performing life-saving missions anywhere in the world, at any time.
