There are two files to download: a set of house rules, and a QRS.
The Rules
I tried to be somewhat detailed in my rules so they run 13 pages. But most of it is really just comprised of three things: an Opportunity Fire / Overwatch rule, an optional hidden movement rule, and a two phase, fog-of-war turn sequence.
The QRS
I used to make "Unit Cards" for my FoW games, like BF now does with their Team Yankee game. It was a small improvement over having to look things up in the rule book, but there were still cards and sheets all over. So I have instead combined the QRS with a unit roster. The stats for each unit are grouped with the appropriate rules section. So movement rates are in the movement section, shooting stats are in the shooting section, and so on. So you will need to take a few minutes to fill it out prior to play, but I think you'll find it really helps speed up play. The small blue cirlces with white numbers are page numbers. they refer to the 3rd edition, small paperback book which is the rules set I use.

DON'T PANIC
The QRS is four pages. The FoW original was two. But I have added the unit stats and printed it in much larger type, much easier to read for my old eyes.
I'm sure I have missed some things, or will need to explain a few things better, but I think you'll find it's very much a different, more dynamic game with this structure.
You can find the download by searching for (yes, really) deep fried happy mice.
