I have attached the OBs for the 2 Pratzen Heights scenarios (Soult's Attack in the morning, Russian Imperial Guard Attack in the afternoon). The total requirements for lead are listed below.

Bruce and I have virtually all the French (Guard arty and most Guard cavalry being the exception). Terry has a good chunk of Austrian foot/arty. Pete is working on providing a bunch of Russians, exact number and content unknown. (Pete: don't think I had mentioned to you the idea of doing the second scenario -- using same terrain -- one after the other so the Russian guards may not be an area you even looked at. No problem.)

FIGURE REQUIREMENTS

(Note: for light cavalry figure requirements I assume basing of 2 figs on command stands, only 1 for other stands. Russian and French foot artillery require 4 crew per stand while Austrian only require 3. All horse artillery require 2 crew /stand. Also, don't know if Russian line foot and Guard foot are interchangeable and can be used in both scenarios so have left the Russian requirements separate.)
