I bought these rules in 2014, as well as 'some' 15mm miniatures from Peter Pig's Range 8. Back then I had a pretty good grasp of the rules, having read them a couple times – all forgotten. I did indeed paint three infantry companies (the company is the base unit size you play this game with) – German, U.S. and British, for 1944. I do have support weapons and tanks and stuff (unpainted) and some resin terrain (back then you bought it, and not 3d printed it yourself… I am old…), also all unpainted.
Once I finish the bare the neccessities for a game, and actually played one, I will update this post here… bear with me…
