Well, my favorite tank is the Abrams. The USA really hit a home run with the M-1, not that I'm partial to home cooking don't you know.
My favorite historical tank is a toughie, sometimes I'm partial to the Tiger and sometimes the Panther.
You gat that right it took us a long time but we finally developed and fielded the best tank in the world. The one thing that amazed me though was the lack of the ability to fire an HE round. I wonder who came up with that idea originally.
