Hi Skratch,
You asked what set of rules I play. They are a homebrew set I have been messing with for about 6 years. The rules are on two pages, really just play charts. All the details are hashed out with the guys I play with. I like to use them at conventions as they are quick to explain. That way I don't have players argue about this guy cannot do that, or some super tank cannot be knocked out by such
and such weapon. If nothing else I can roll some dice, tell the player the result and get on with the game.
Does that make sense? The funny thing it works, gives the flavor of WWII, I try to remember the KISS rule.
