Modern land warfare, based on Spearhead. This is a complete game, ownership of Spearhead is not needed to play it.
It comes with many ToEs, for US, UK, NATO and Soviet forces, as well as various Arab - Israeli conflicts.
There is a great support group at Yahoo, with ToEs for many nations & time periods. Players can easily control a brigade or two. Even a full division can be used, but this takes more time.
Units are platoons, designed for 1/285 scale, but can be played in 15mm also.
