The Battle of Jutland at individual ship level (for the big ships) and squadron level for destroyers and light cruisers. Each shipping counter represents a battlegroup of 1 to 4 ships and has 1 or 2 gunnery target counters representing big and/or small guns.
To hit a ship with gunfire, a die must be rolled. Then if a 'hit' is scored, a 2nd die roll is made for penetration (actual damage, sinking one ship of the counter's battlegroup)
Victory is determined by sinking enemy ships.
