Per email conversations with Mr. Glenn Furbish
I was in the original platoon of the 120th AHC sent to Phu Bai in February 1968 that ultimately became the Corps Aviation Company so I can speak to our early years.
The 120th AHC was in Saigon when TET started but in early February one platoon was sent to Phu Bai. That was in the middle of the Tet offensive and all of our early missions were resupplies and medevacs of the citadel. Once Tet ended our missions moved north in support of the siege on Khe Sanh. I remember numerous missions in and out of Khe Sanh. We were primarily a unit that supported I- Corp Headquarters but we also supported other units that were without helicopter support such as the 5th Mechanized Division and the 108th Artillery Group (I may be wrong here. It might have been the 106th or something similar). Nonetheless, we participated in Khe Sanh, Ashau Valley, and other major engagements. , I have been thinking about our early days in Phu Bai and, not trying to tell war stories, it was an interesting time. The unit had no casualties while I was there but flying I Corp was always interesting. At least one USMC General was killed in a Marine helicopter crash because the USMC was flying old helicopters that underperformed in the high density altitude we had to work in. The Corps Aviation Company sent a bird everyday to Dak To to fly the USMC General in charge of the area around.
Somewhere along the line we got some OH-6s, and I was the first pilot to transition to an OH-6. As I think I mentioned earlier we supported the 108th Artillery Group (I could be wrong about the designation) so a lot of my missions were directing artillery. On occasion I would direct fire the battleship US New Jersey. Those 16 inch guns were amazing. Anyway, it was a life-changing experience.
The call sign "Coachmen" was originated by my unit in respect for our core mission supporting I Corp.
