No. but if you just buy AA42, you get a bunch of new pieces (including A and A guns). And it’s only like 25$
That’s your best bet. Plus you’ll get a lot of extra units so you don’t have to use poker chips.
That is what I did with AA42. My boys didn’t want their copy so I bought it, with 1 game played, for $20 to add to mine. Now I need a bigger table so I can print one of IL’s maps for AA42 to have a good sized board for more pieces and less chips used.
