Volumetric armor only on soviet tanks?

Anyone devs or gamemaster can tell me about volumetric armor? volumetric armor exsist only on soviet tanks? Because USA tanks dont have VOLUMETRIC armor. Can you tell me why? And why HIT ANALYSIS is broken? and you cant trust this function?

Volumetric armour is being added to vehicles slowly ever since it was first introduced so not all tanks have it.

Have you heard of t58

I am equally curious, is there any good video explanation of how volumetric works?

Just play with russian imortal KV-1 ZIS and you understand how volumetirc works. No, play with any russian tank and you understand how volumetric and stalinium armor works.
USA tanks have pixel paper armos



GUN shield pixel paper armor
