I started out on M60A1 AOS (Add-On Stabilizer)and regressed to M48A5. First time I ever heard an M1 I thought it was an OH-58. Then I saw it. Watched it back into a woodline and burn down a tree.
Slow down, we will tell our ages and be considered geezers or worse. As OrdC I started on M113's, M48A3C, M114A1E1, and a host of others. I remember the first Gamma Goats and when the GOER came on board we thought it was great. Sheesh, lots of water has gone down the river in the past 33 - almost 34 - years.
