Also note that Risk – the plain basic edition, not one of the countless spin-offs – has little plastic Napoleonic sculpts of infantry, cavalry and artillery, in multiple colours. On the minus side, they’re kind of small, but on the plus side the game is cheap and readily available, so its units could perhaps be used to supplement the bigger ones from other games if sheer numbers are needed. For instance, as a variation of the A&A concept of using mini poker chips to represent multiple units, the little Risk units (which are too small to be a good choice to use as the main game pieces) could be used on the board alongside the big ones to represent extra groups of five (or whatever) units.
