Frank Chadwick’s ETO (European Theater of Operations) is a series of
linked games covering the land campaigns of World War II in Europe using
a constant map and unit scale, and common rules.
Thunder in the East is the first game in
that series, this one covering the titanic struggle on the Russian
Front. This is a two-player game (although teams or even solitaire play
would be just fine): one player assumes the role of the Axis (Germany
and its allies) and the other player assumes the role of the Soviets
(i.e., the Soviet Union).
The individual ground units represent Divisions of 10-15,000
soldiers, Corps (from the Latin word "Corpus," meaning body) of
approximately 25-50,000 soldiers, or Armies of approximately 75,000 or
more men. The Soviet ground units are mostly armies of approximately
40,000 men each, with a few cavalry and airborne corps of about 10,000
Air units represent about 200 combat aircraft early in the war, and
gradually more as the war progresses. Each hex on the map represents 30
miles of actual terrain from side to side, and each Game Turn represents
the passage of 7.5 days (or up to 15 days during inclement weather).
