Aurelius Vorn:
Do we need to spend any profit or funds on a regiment for the barracks?
It's covered by the module itself. Though I'd say you could upgrade the quality / equipment of your troops as a Rare / Very Rare purchase.
Also, any thoughts on where they might have come from? Leased from an Imperial Guard regiment? Loyal household troops?
I'll also note that one of the reasons I like Savage Worlds is that you can actually run a battle with lots of Extras, and not have things slow to an agonising crawl, since they're either okay, Shaken or out of action.
I'll kick things off tomorrow. :-)
