Good News, the sniper in Germany 5 holds his position.
I think it would be easier to make a summer skin for the Sherman tank, and then say it's a Lend-Lease tank. But if you prefer the challenge of making a T-34, then you have my blessing. Will it be a T-34/76 or a T-34/85?
Instead of deleting Germans, you should "reposition" them. The Germans are on the retreat, after all. Move the 4 Germans that were guarding the bridge, and have them strengthen the hill's defense. Same with the 4 on the terrace. That would make taking the hill a HARD challenge.
In Prague, there are only 2 real paths-of-retreat the Germans can use, the main road that is the spawn-point and escape point, and the other is the dirt road right behind the cannon. Add one or two more trucks on the dirt road, that the Germans plan to use when they have to retreat.
It would make more sense for partisans to attack from the rear, as there is no way the Soviets got there. Have some Russians spawn from the bridge, and head towards the alley where the 3 civilians come from.
More partisans can spawn from behind the pile of wrecked cars, (the first roadblock), and try to liberate the church, only to be mowed down by the MG42. Or they could get blown up by a Panther or PzIV guarding the escape point. (The tank would be "covering his comrades' retreat.")
The 4 or 5 sentenced civilians and the 3 officers about to execute them should also be moved to either the square, the terrace, or that indent in the road behind the church, as the place they are now is too isolated, and ESPECIALLY too close to the Russian lines.
