Talk:12.7cm Twin Gun Mount Model B Kai 4 (Wartime Modification) + Anti-Aircraft Fire Director/@comment-25283939-20180712072700/@comment-26464279-20180712165348

With the stock equipment of Shiratsuyu K2 I'm surprised she only needs a AR and not also a BP.

T22K4 +4 and Model C gun aren't exactly common equipments and Choukai, the only other ship that gives the T22K4, also needs a BP for a non-upgraded one.
