The Guns of U.S. Army Aviation in Vietnam — Personal Defense Weapons on Slicks, Snakes & Loaches

The U.S. Army has never been a particularly agile beast when it came to bold new technologies. Horse cavalrymen were dragged kicking and screaming into tanks during World War II, and the grunts and tankers of the ’50s viewed the helicopter with a tolerant skepticism at best. In 1963 the 11^th Air Assault Division was testing the practical aspects of air mobility at Fort Benning, Georgia. Two years later the 1^st Cavalry Division (Airmobile) went to war.

The war in Vietnam saw the introduction of a wide array of new technologies. From smart bombs to night vision and lightweight assault rifles, Vietnam was a proving ground for countless new weapons and the tactics that drove their employment. As a result, flight crews operating Army rotary-wing combat aircraft frequently made up the rules as they went along.

There really was no precedent for what those guys were doing. UH1 Hueys and CH47 Chinooks carried troops, ammunition, equipment, and supplies into places that would have otherwise been inaccessible. The use of massed helicopter assets allowed Army commanders unparalleled mobility around and above a non-linear battlefield. Light and agile aeroscout aircraft like the OH6 provided responsive intelligence gathering. Armed versions of the UH1 and later dedicated AH1 Cobra gunships offered responsive and overwhelming aerial fire support. Throughout it, all Army flight crews operated in the treetops engaging the enemy face to face in a pitiless close range fight to the death.
