@elkikko:
Thanks. So which old espansion or tactics kit has a Lot of units with rules?
I want to buy 1942 axis And Allies. Which kit to buy to add good units and more veichles strategy!
Your best option, in my opinion, is to buy A&A 1942 2nd edition, and to supplement it with some of the battle pieces currently produced by Historical Board Games:

I don’t think HBG’s battle pieces come with rules, but many of its custom markers do…

…so you could probably make use of some of these rules.
Another source of rules, or at least of rule ideas, is this section of the forum…

…if you’re willing to take a bit of time to look at the post titles to find sections that might interest you.
If I’m not mistaken, the old supplementary unit packs produced by Table Tactics…

…did come with their own rules, but they’ve been out of print for a long time. You may still be able to find them on the secondary market.
