Speaking of military utility or fatigue uniforms: while I was assigned to Fort Ord California (now closed) in the mid-sixties, that post had a policy of everyone in garrison wearing the fatigue uniform every day. Class A uniforms were limited such as for the military police, but they reverted to fatigues when off duty.
Fort Ord had an additional apparel requirement that I have never seen anywhere else in the army.
The post required that an ascot tie be worn with the fatigues. The ascot was commonly called a scarf by the troops. Below the chin there was a white tee shirt (later olive drab) area showing. Fort Ord dictated that this area be covered with the ascot tie; no part of the white tee shirt could show.
Each troop wore an ascot in the color that was the official color of his Army branch. For instance, the 7th Cavalry was stationed at Fort Ord and they wore a bright yellow scarf. Infantry types wore a powder blue scarf, artillery types wore a bright red scarf, military police wore a bright green, medical personnel wore maroon, signal corps wore orange, finance wore light gray, etc.
Well pressed fatigues, polished combat boots, and an ascot tie made for a nice looking utilitarian uniform.
Fort Ord was unconventional in another way. Other army posts had their acres and acres of World War II buildings painted a subdued yellow. Fort Ord buildings were painted a light but bright shade of green.
