I'd like to try out these rules. I'm thinking of doing something similar to the games Baccus did at shows using a 4'x4' gridded table, such as the "Gettysburg Gallop" (

Anyway - in reading over the rules, do the units need to be facing a specific side of the square? I ask since there are modifiers for flank and rear attacks. Of course, you still don't need facing to have a flank or rear attack (example: if you attack from only 1 square it's a frontal attack, if you attack from 2 squares which are 90 degrees apart it's a flank attack, etc...) but still, I'd like to know how the author(s) play it...
