Here’s a set of free wargames rules for operational level actions during WWII. Battalions are represented on a 2×2 base, and the entire thing is inspired, it seems, by Volley and Bayonet.

Not Quite Mechanized rules
Chris Kemp offers Not Quite Mechanized, a free set of operational level WWII rules. With the great emphasis on skirmish rules these days, it’s refreshing to see a set of large scale rules. Here’s what Chris has to say on why he decided to write an operational level set:
The idea for NQM began in the 1980’s when there was a dearth of fast games that allowed large multiplayer games to flow smoothly with a minimum of fuss. My experience of large cloth-model games at RMA Sandhurst with Dr Paddy Griffith and others, created a yearning to be able to re-create the vast sweep of those games, but with a far less intrusive umpire load. The players would be able to handle all the low-level combat themselves, leaving the umpire(s) free to concentrate on the high level decisions. Oh, and just to make it harder, the game had to be able to handle a couple of players wanting to have a knock-about on a Friday evening. Whether or not I succeeded, you can judge for yourself.
