Whoa! I am being mentioned in the same breath as Phillip (and not just at the human males with pulses level)!
The best way to defeat the Red Banner is to attack it. Being on defense turns off the (annoying) point-stealing for me while leaving it on for you. Plus, it is usually configured for attack. The Shturmovye may be top of the shelf infantry, but sitting in foxholes getting shelled, they are little better than most late-LW German veterans. I can swap some for mediocre guns, but that hurts headcount, so is often a weak option. As long as you do not get careless and enter within charge range I mostly just sit and take it with only Fearless distinguishing me from a large PzGren platoon. If you have auto-attack mech or tank I have to defend, which leaves me very weak in many missions.
1515 is actually a very awkward points level for the Banner, as I recall. 1420 was pretty good because I got the core elements and just enough support to hit 4 useful platoons. Adding only 95 pts leaves me with tough choices. 6 useful platoons is hard to come by (Soviets so rarely get any of those nifty tiny platoons that do something well, like German infantry guns or Nebs - and the few they had mostly seem to have disappeared by the late-LW lists), so trying to find a way to spend it on the 4 can actually be tricky.
