Terra Nullius

JW! Great to see you're still around and modding WWII games. I remember your most excellent work on the Sudden Strike series.

I tried to put the two guns in as much cover as possible in the set-up phase, then instantly de-crewed them at the start of the battle and had the crew lie down, hold fire and hold position in the grass near the guns. An empty gun is no threat to the tank crews. Then once the tanks were in range and busy shelling the guys in the trenchs I remanned the guns and opened fire. I still needed to dash men from the trenches to reman the guns when they were hit but eventually they prevail. See if that works for you.
