Military Field Manual For the Transport and Care of Abominable Snowmen.

California Army National Guard’s Bravo Company 1-126th Aviation Regiment, Delta Schooners, based out of Stockton, flew two of their CH-47 Chinooks to the Marines Mountain Warfare Training Center in Bridgeport, Calif., high in the Sierra mountains to support Hawaiian-based 3rd Battalion, 3rd Marines conducting high elevation training. More than 600 snow-clad Marines armed to the teeth and packed for an extended stay in snow conditions were airlifted to their landing zones in multiple insertions. During the operation Utah Army National Guard’s 1-211th Attack Reconnaissance Battalion AH-64 Apache helicopters circled above providing protection to the Marines who were made up of weapon and mortar platoons, to name a few.
