|DE are primarily used for ASW. In the event they are used for combat, green dual-purpose guns like the [[10cm Twin High-angle Mount]] contribute Fleet Anti-Air (FAA) while allowing destroyers to perform night battle double attacks. Ideally, using the [[10cm Twin High-angle Mount + Anti-Aircraft Fire Director]] is preferable. Destroyer guns do not provide enough extra firepower to allow them to contribute to day combat. The extra FAA from dual-purpose guns will help more by mitigating airstrike damage. The wildcard can be anything that doesn't interfere with double attacks. In most cases, this will be an {{Air Radar}}. This will allow any destroyer to activate AACI API5.
