Hi Dave:

I'm planning a couple of military trains myself; it's almost obligatory for the 1970's. According to Wikipedia, 1A4's were just starting production in 1974, so they would be usable for the middle of your timeframe anyway. I'm planning to use some 1A1's (if I can find some) for 1970.

I imagine American or British military movements would be equally suitable. Modelling northern Bavaria, I would have U.S. Army trains, which would use M48's and M60's from what I gather.
