An introductory wargame, noteworthy for having been endorsed by one of the leading British generals of World War II. The board consists of a plain grid of green squares. Terrain features are printed on vinyl that may be temporarily attached to the board creating a unique battlefield for each game. There are three types of unit. Tanks move more quickly, while Guns can fire over a longer range. Aircraft can attack targets anywhere on the battlefield, but risk being shot down each time they do so. The winner is the first player to achieve a 3:1 superiority in remaining units.
