The Sky Devils were a helicopter squadron led by Preston Packard during the Vietnam War. They were recruited by Monarch official Bill Randa as a military escort during the 1973 Monarch Expedition to Skull Island. They suffered major losses during Kong's rampage which led their commander to go on a maniacal quest to kill Kong. Jack Chapman was killed by a Skull Crawler and several more men were killed by the same Skull Crawler while they were traveling through The Boneyard. Another soldier was killed by a Mother Longlegs and Earl Cole was later killed by Ramarak after a failed attempt to trick Ramarak into eating him. At the end of expedition, only a few men were lucky to survive. The remnants of the Sky Devils were likely disbanded. The Sky Devils were stationed at Da Nang Air Base.
