Originally, when upgrading equipment, the corresponding equipment of its type is consumed.

Different type of consumption appeared when certain rare equipments that are really hard to farm (such as Bismarck guns) appeared on the list, so the devs started making exceptions.

I think they should rework consumption thingie, those 20.3 no.2 and no.3 are hard to farm (although not as hard as some other equips).
