These are my two from my Vietnam units in 1972. The 1st is from F/79th Aerial Rocket Artillery, more commonly known as "Blue Max". This unit was the former C/2/20th Artillery. There were also Alpha and Bravo Batteries as well as Charlie. F/79th came into being when "Task Force Garry Owen" was formed from the remaining units left over in Vietnam from the 3rd Brigade of the 1st Cav. (Airmobile). The original unit arrived in Vietnam in 1965 with the Cav. and supported Col. Hal Moore at the well-known battle of the Ia Drang Valley. Blue Max stood down and returned to Ft. Hood, TX in late July 1972. Blue Max won their 2nd Presidential Unit Citation in 1972 for their efforts in the Battle of An Loc and was the Army Aviation Unit of the Year in 1972 for being the first Cobra Unit to successfully engage and destroy Soviet-built main battle tanks (T-54's & T-55's) in combat for which the Cobra was mission-specifically designed to do.
The 2nd patch is from Troop H of the 17th Air Cavalry Squadron. Troop H was the former B/7/17th Cav. and came into existence in early-1972 when the 1st Aviation Brigade was formed for the remaining Army Aviation Units left in Vietnam at the time. We were a typical Air Cav. unit doing the Hunter/Killer "Pink Team" recon. mission to gather intelligence on enemy movements and locations. The Guns were callsigned "Undertaker" and the Scouts were "Scalphunter".
