Here's a handful of fighters I used in my fantasy campaign. I originally created them when the players visited a militarized area of Amity and I needed a couple dozen uniformed, armed guards.
I've since used them in other settings, just color shifting them and messing with the logos on their chest. The players always know they're in for a fighty good time when I place a handful of these guys on the table.
