I’ve had a look through the rules, and I don’t believe there is a hard cap on formation size.
‘Western’ forces tend to have tank companies between 2 to 4 stands, and infantry companies of 3 – 4 stands plus transport.
Soviet and Third World forces have larger units, with the basic maneuver unit being a battalion. Most of the lists have tank battalions listed as 6 stands, , although in some cases in the Soviet list they can be as large as 9. Infantry battalions are similarly large, generally being 9 infantry stands, plus transport; sometimes with attached assets such as ATGW, Mortar, or ATG.
So I was doing some rough scibbling, ideally we should be able to raise a Brigade of Western military? Are people planning on creating their own imaginary forces, or just using existing lists?
