Fudge Tactical Combat
This is a set of combat rules for Fudge that use miniatures and a hex grid, available under the OGL. It does add more crunch than is typical for a Fudge game, since after all you're now keeping more precise track of distances, relative positions, and movement rates. However, if you are a visual sort of person who finds combat easier to get into with some physical aids to help you visualize what's going on, this set of rules might help make combat more fun for you. Check them out, and feel free to use whatever part of them you like.
