There is a FAQ/Errata for Allied Assault but not as yet for Russian Assault so I thought I'd start a thread to compile one. Please feel free to add to this thread any official corrections.
I have clarified a couple of things with Matt at Petroglyph Games to get the ball rolling....
1. There is an error in the manual for the first solo scenario Moscow. The manual says that the win condition is to destroy 9 German units, but only 6 are ever placed. The win condition should be 6 not 9.
2. In the same scenario the manual says that the player should start with 12 action cards. This is to be interpreted strictly and none of them can be unit cards.
