* Much like the 12.7Ck2, the [[12.7cm Twin Mount Type-D Kai 2]] provides some nice fit bonuses to destroyers. Unlike the C-type, it doesn't work with Shiratsuyu and Asashio-classes.
+
* Although weaker than the Akizuki 10cm and the 12.7Bk4, the [[12.7cm Twin Mount Type-A Kai 3 (Wartime Modifications) + Anti-Aircraft Fire Director]] is easier to obtain. They can be useful to fill out your destroyer gun lineup if you don't have enough of the two former ones.
+
* The [[Type 3 Shell]] and [[Shipborne Model Type 4 20cm Anti-ground Rocket Launcher]] are both important anti-installation equipment. Ideally you should have a pair of each at their advanced versions.
