I just finished this. Won as the Russians. Several keys to Russian play
Pick an area of buildings, and defend that with all of your force. Do the math. Know what you need to hold to win, and hold only that.
Concede the rest.
Use the Foxholes for rout path planning
You cannot allow your force to be taken prisoner
Plan your fire fields, goal is to fire every weapon, every fire phase
Know the German only has 6 turns, thats not a lot of time.
Start your mortars and HMG dm .. run them to the fight, don't leave them back
Don't bring your tanks across the river, unless they are safe, they are CVP opportunity otherwise, and thats all
Use 2 Commisars, and as I said, plan your routs
Self break to avoid being taken prisoner
Normally a good tactic, but even more so in this scenario, shoot at broken units looking for CVP
With the Russians packing it into one area and playing it safe, what looks like a really cool scenario on the card, ends up being not quite that.
This could get into a fight for the town all over the map, but as the Russians, don't let it come to that. Hide, skulk, keep all your squads safe.
I liked the original Balta scenario a lot better.
Glad I played it, but wont' again.
