I can upload pics later ....    Might have a few of interest.    Yes, I actually trained on USA M60A3 tanks for 14 weeks at Ft Knox, KY.   The 105 mm is more than just accurate.  At the range, we were hitting targets at 3000 m  out with a pattern about the size of a large pizza box.    Firing at night can be even more awesome with a large flash and streak of red tracer, which you notice your eye retina has seen before you had shut your eyes from the noise boom.  Anyway .... just a litte about me.
