Olympic & Coronet is a hypothetical simulation on a regiment-brigade level of the planned invasion of Japan. Olympic is the planned November 1945 invasion of Kyushu, the southernmost Japanese Home Island, while Coronet is the planned March 1946 invasion of the Tokyo Plain.
As the Japanese were committed to a strict operational plan organized around the theme of an aggressive beach defense, the basic version of Olympic & Coronet is a solitaire game in which a single player controls both opposing forces. During solitaire play, you should alternately direct each opposing force so as to maximize the ability of each to fulfill its particular victory conditions. You will have complete control over all American (US) units, while the Japanese units will be restricted by their doctrine rules. To as great a degree as possible, those prescribe how and when Japanese units move and fight. The Japanese doctrine rules fill the role of the absent Japanese player.
In addition to the basic solitaire version, rules for a two-player game, and optional rules for the solitaire and two-player versions are included.
In Olympic, the American objective is to rapidly destroy or drive all Japanese units from the extreme southern portion of Kyushu, and to do that as economically as possible in terms of American casualty points. The Japanese objective is to prevent the American objective from being attained by inflicting the greatest possible number of American casualty points and continuing to occupy and defend southern Kyushu for as long as possible.
In Coronet, the American objective is to rapidly destroy or drive all Japanese units from Tokyo and the surrounding area, and to do that as economically as possible in terms of American casualty points. The Japanese objective is to inflict the greatest possible number of American casualty points and continue to occupy and defend Tokyo and the surrounding cities and towns for as long as possible.
