Christmas 1984 - my Uncle got me the M.O.B.A.T. with swivel-arm Steeler. I actually have photographic proof to help my memory with those two. I am 99% sure that I got the Machine Gun Defense Unit that morning too, but I'm only about 80% sure that I also got Short-Fuze, Rock & Roll, Grunt, Breaker, and Helmeted CoCo that day as well. Regardless - it was a great Christmas!!
