At Fort Irwin, R. Lee Ermey checks out the Army's state-of-the-art air ambulance--the Blackhawk helicopter; then, he learns why the helicopter became so important to Korean War MASH units that it was dubbed "The Angel of Mercy". Then, he reviews the history of America's First Special Service Force, created in WWII and nicknamed "The Devil's Brigade" by the German Army; sees which Cold War superjet is tougher--the MiG-15 or F-86 Sabre; and checks out the first US operational jet--the P-59.moreless
