From the list of components needed for this scenario, it seems that two copies of the base game are needed as well as two copies of Fury of the bear. 2 base games because 18 German elites appear to be needed and 2 FoTBs as 11 expert tokens are listed. Is this correct? I do own two copies of FoTB, but I do not have two base games. I just filled in the remaining elites by means of replacing them by regulars.

I gotword from the scenario's designer that the number of listed components is correct. I suggest using US elites and uoside down fatigued counters at the back of the squad bases to represent the troops and tokens most players will be short of. The scenario's a very good one, so it'd be a shame to not give it a go because of this!
