If you can find a copy, my old book WW2 Battlezones published by TTG has 33 assorted scenarios for battalion level games.
I see one went for $55 on ebay recently, wow, it cost £4 when it came out!
I have some of the Anschluss Wargames scenario books, they are very nicely presented, mainly because they pick less well known actions. They seem to be based on one base is a squad, one vehicle is a vehicle type rules, from single company upwards, and can be reconfigured for other rules sets no problem.
