Rembrandt1662 
A battalion level battle on a 3000x3000m rural map. A German tank destroyer battalion supported by infantry mounts an improvised defence of a wooded ridge and a group of villages against a Soviet armoured breakthrough. There are AI plans for both the Germans and the Soviets. The battle is essentially a long range massed tank duel with some very unlucky infantry caught in the middle.
Nice scenario ! But so huuuuuuuge that it really requires a powerfull computer. My i5 W10 12Go+ Nvidia 2Go is overloaded, even with low graphic game settings.
