The new book, Red Banner, adds a whole new aspect to the Soviet forces in Flames of War. It combines with Enemy at the Gates to allow you to build a wide variety of forces, with plenty of different play styles.
What's In It?
The basic Soviet tank force. Lots of fast, tough, well-armed tanks, but little finesse. Being hit on Reckless 2+, you can expect lots of casualties, so swing the sledgehammer hard and fast.
The later model T-34 with its re-designed turret and commander's cupola makes it faster and better at crossing obstacles. This is really great for amassing an overwhelming force and getting flank shots. You can have nothing but T-34s if you want.
The T-70 is cheap, but still mounts a 45mm gun and good armour.
The improved Valentine has a bigger turret giving it either no penalty for shooting on the move with its 2 pdr, or a powerful 6 pdr (but with no MG!)
