A note on Beer Wagon, it is a "Falcon" gunship from the 3rd plt of my old out fit the 335th AHC "Cowboys" at Dong Tam. We shared the field with the "Emus" a joint Austrailian/American helicopter company. Their guns were the "Tipans" named after the snake. The Falcons took their emblem from the "Atlanta Falcons" football team, with the addition of red paint on the Falcon claw to simulate blood.
The white tirangle with the pentagon inside indicates the battallion, in this case the 214th out of Vinh Long. The pentagon was different colors for different companies. The 335th for example carried a blue pentagon. Also of note, the drive shaft cover atop the tail boom, the 42 degree box cover and the verticle fin covers were painted black on our company aircraft. And the stinger cover (a flexable fiberglass piece which faired the end of the tail boom to the verticle fin) was usually painted to a platoon color. During my tour, yellow was first plt, white was 2nd plt, and the guns were black.
To add to the confusion factor, sometime about 1969 the Army issued an MWO (Modification Work Order) to install "C model" tail booms and sync elevators on all "B models". In the case of the guns paint and or other beautification was done as time permitted because the guns flew a much heavier schedule than those of us in slicks. Many gunships flew a while with with just zinc chromated tail booms.
