I think I have spent over 2 hours reading rules and forums, and now have a concise understanding of all the rules with one exception(thanks Warfrog).
When you take control of a region's military you retrieve one unit with the lowest value from the "dead" pile. At the beginning of the game do you skip this step as there are no units off the board, and if during the game there are no units to recover do you just not recover them?
Yeah, just skip it. You already have all the units at your disposal.
