Thanks for the quick replies.
Costard, I have been playing a German Assault with about 700 points, early war June 1941 Central front. Computer generates both sides, terrain is rural with light trees. Mech Infantry Vs Mech Infantry, I play the Germans. I will check the archives and see what I can find.
My ammo levels are very low when it happens so SuomiStug's logic seems correct except I was playing an assault. I've done this 3-4 times and each time I'm winning and the game is in the later turns - ceasefire is declared by the computer and the game ends.
You know, sometimes you just want to wipe out the computer
