However, the armor unit can repair this damage in one turn in a city. Essentially, you are producing a new infantry unit in one turn. This and its speed make armor the preferred ground unit, in general. Fighters At least initially, you should use your fighters for recon only and to attack only bombers and transports. Bombers Although primarily used for bombing, you can exploit the range of these for recon purposes, but be very careful in areas infested with fighters.
Fighters have a significant advantage when attacking bombers.
Maintain an offensive posture. Destroyers Get them out there hunting transports. One good tactic is to have destroyers roaming the channels and seas lying between the enemy and empty continents. Sending them behind the lines makes it more likely they will be spotted, allowing the enemy to better redirect his transports and attack you with capital ships. Cruisers Keep your cruisers close by important port cities or sitting in narrow channels, ready to pick off those pesky transports and destroyers.
