From the back of the book:
SEA COMMAND gives you the chance to take command in the most dangerous seas--those of the 1980's. Only those who command actual warships can claim to have a better knowledge of what it requires to win--and survive--in the dynamic and multi-faceted modern war at sea.
War at sea is today more complex and fascinating than ever before. SEA COMMAND is the follow-on to Enola Games' acclaimed WARSHIP COMMANDER and, in conjunction with it, presents the full picture of modern naval warfare. SEA COMMAND includes:
---full rules for submarine and anti-submarine warfare,
---full rules for aircraft operations: fighters, bombers, helicopters, etc.,
---rules for using a referee system that provides the maximum in realism,
---a complete list of technological changes and advances that can effect modern naval combat and how they are reflected in the rules, and much more.
