This is a simulation of battleship combat, which abstracts each ship to four numeric attributes: attack, defense, speed and range.
What you get is a thick paper map (22" x 16") showing some coast outlines in different colors, 200 ½" cardboard counters, a 12-page rule-book and two dice. The counters represent WW2 battleships, cruisers and destroyers of various nationalities, plus markers to show ship speed and direction, targets, and damage inflicted.
