In large games of Impetus it can be difficult to keep track of which units are in which commands and whether they have yet been activated, so I made these markers from pennies (for weight) sandwiched between plastic counters and stuck with superglue. I have to admit that I'm not very good with superglue. Regardless of how careful I try to be - and I'm well aware of the dangers - my fingers seem to attract it like a magnet. Each unit begins with a colour indicating its command. Once activated you turn them over to show black or white for the two respective armies. At the end of the game turn you turn them all back again.
