Every time I think this tank is done surprising me, I find something that makes me stop and say "Oh, wow..."
I decided to use the turret temporarily on my Sherman until I get it's IR one working. This of course meant that I had to change the solder connections to a 3 pin. When I poped the turret open I found this.
Whatever they shot this thing with, it was strong enough to penetrate the side armor AND the airsoft unit!
