Simulated casualties rest on stretchers during Tiger Rescue IV, March 28, 2018, at Vandenberg Air Force Base, Calif. The four-day exercise challenged Airmen from multiple rescue squadrons to bring the capabilities of the personnel recovery triad together to successfully complete rescue missions and maintain proficiency. The three branches of the personnel recovery triad are the HC-130J Combat King II, HH-60G Pave Hawk and the guardian angel weapons system or pararescuemen.
