Pvkv III should also get APDS Due to it having the same cannon as the Pvkv IV

The Pvkv II, Pvkv III, Pvkv IV was made during the same time period and both the Pvkv IV and the Pvkv III have the exact same cannon with the exact same calibre of 57 mm × 385R mm

I am going to be honest, the apds doesn’t really mean anything if your turret traverse is 3 degrees a second. Ligit the IV is unplayable at 3.7. No armour, no speed, and a gun that takes half a century to get on target
