您好美国海军，

这不是错误，而是功能。枪支本身是不同的，因此它们在游戏中的显示方式也有所不同。意大利（上图）装有4支枪，下图所示的维托里奥威尼托有3支枪。 

具有相同数量枪管的枪也有不同的外观。 

我希望这回答了你的问题。

I am not talking about the different barrels or turrets in the picture above and the picture below.

 But the barrel colors of the two turrets on the same ship are inconsistent. Please note that the red barrel is the black barrel (BUG), and the cyan circle is the gray barrel (no mistake).

 I found that only Italian battleships have this "BUG".  Please fix this "BUG" .. Thank you.

I found this "BUG" for a long time, the Italian ships will be like this, that is to say, the color of the turret and barrel will always change.
