Battlestations: Midway/Neutral

Many ships and land installations are either neutral or are used similarly by both sides. With only two exceptions, they are not used in-game.

Land Installations
There are several different kinds of land installations: Only two are playable, and even then there isn't much to do with them.

Shipyards

 * Strong Against: Sea Attack
 * Weak Against: Air Attack

Shipyards act just like aircraft carriers, only they don't move and they launch ships instead of planes. What kind of ships they launch is dependant on the level. Sometimes they can deploy only patrol boats and seaplanes. Othertimes, Battle of the Solomon Islands being the most notable example, they can deploy entire fleets, backed with cruisers, destroyers, submarines, and even battleships.

Shipyards, due to their nature, are vulnerable primarily to air attack. The hit-and-run nature of aircraft allows them to strike at odd angles and from out of reach of shipborne anti-aircraft fire.

Airfields

 * Strong Against: Air Attack
 * Weak Against: Sea Attack

Ironically, while shipyards are vulnerable to air attack, Airfields can repel them easily if players act quickly. As soon as an air raid is detected, if all fighters are scrambled, oftentimes they can inflict a lot of damage to the enemy formation and nullify most of its attacking power. Against enemy warships, however, particularly battleships - dive bombers and even torpedo bombers rarely cause enough damage to sink enemy warships quickly enough to save the airfield.

Therefore, strangely enough, sea power is best countered with air and air power is best countered with mastery of the sea.

Note that when attacking an airfield all that must be disabled is the hangar which spawns the planes. All other buildings, including exposed aircraft on the ground, are useless and are merely there for decoration.
