As this was a test run for a capture the flag scenario, and based on Kasserine, I have a few suggestions.
1 - Use the M4/75 instead of the 76. The Panzer III was way outclassed by the 76.
2 - Remove the M-18. It wasn't available.
3 - M-3 should have the 75 available. It might have been, but I didn't try it.
4 - Turn off the field guns.
5 - No spawning available from captured field. It was literally impossible to recapture this base when your opponent can re spawn from the exact place he was just killed. Yes I know we could have taken down the VH, but there are 4 of them, with bad guys shooting at you, all the while you are fighting uphill.
Carry on
