Here's a simple variant (almost
purely for fun's sake, especially considering I haven't tried it yet).
Did you ever have a well-meaning family member give you LCR https://boardgamegeek.com/boardgame/3522/lcr
as a game for your birthday or Christmas?
You wondered what to do with this 'game' that has absolutely no decisions involved with it. I have the answer!
Any time you turn in an "Order N units X" you can choose to roll n-1 LCR dice to at least eke out a little random command. The L, C and R refer to a single order in the given section, and the black dots indicate no effect. [For those who don't know, in LCR, you get three identical dice, each with the facings L,C,R,dot,dot,dot]
For example you don't have anybody on the left flank so you turn in a "Order 3 units left card" and say you want to roll the dice. You roll two LCR dice and get a dot and an R. The dot is nothing, but with the R you can command 1 unit right.
For inspired leadership, you can choose to roll 1 die instead of the listed section. You can then use inspired leadership on whatever section comes up.
I would not suggest this as a necessary add-on, but it may be fun (and I don't think it is game breaking at all, due to the dice having no effect at least 50% of the time).
