Armati II gives a pretty good game, not sure if the rules are still available. It was these rules that got me into historical gaming during my youth at the local club.
I like NT rules, AMW and those presented in wargaming an introduction. As mentioned previously, they fit on 4 sides of A4. Not hugely detailed but give a decent game utilising ‘standard’ basing so elements can be used for a variety of other rules without rebasing.
Good look on this particular foray!
