The slouch hat has been known in the US military at least since the American Civil War, being fairly common among officers. 

The standard headgear for US soldiers in the [[Vietnam War]] in the 1960s was a fatigue baseball or field cap that offered little protection from the sun. Local tailors made a slouch hat in a style between a French type bush hat of the [[First Indochina War]] and an Australian type bush hat with a snap on the brim to pin one side up that was widely bought and unofficially worn by American troops in Vietnam.  The local tailors usually used green fatigue cloth or leopard skin pattern [[military camouflage]] from old parachutes.{{Cn|date=May 2023}} The hat often had a cloth arc emblazoned with the word VIET-NAM on the brim.{{Cn|date=May 2023}}  The US [[1st Air Commando Group]] members officially adopted the green slouch hat on 22 May 1964<ref name=Chinnery/> as their distinctive and practical headgear.

In 1972 the [[United States Army|US Army]] authorized female drill sergeants to wear a bush hat based on the Australian design as their distinctive headgear. This was originally beige, but has been green since 1983.<ref>{{cite web |title=U.S. Army Drill Sergeant |url=https://www.army.mil/drillsergeant/history.html |website=www.army.mil}}</ref>
