Gopher I would follow krieghund’s link if you are playing the Xeno board game. If this is question regarding TripleA WAW variants I can’t really help I’m not an experienced TripleA user and I’m not even sure if TripleA’s clone is a “genuine clone” as WWII is a “clone” of Axis & Allies. Try posting in the “variants” section of the A&A.org site, you may find your answer there.
Personally I never bought or played any of the Xeno games or pieces but at one time they filled a niche where A&A was absent as well as Table Tactics.
Best of luck.
