Russians will hate the lates

[RedDevil]

bolted armor, while certainly better for keeping out high velocity hornets, was actually a bad idea, and the end results were rolling thicker sheets of steel and going 1 piece.
why was it bad?
Bolts, when hit by a projectile going X# of FPS, tend to splinter INSIDE the vehicle and do more damage to the crew and internals, than a penetrating AP round tended to do.
The bolts absorbed all the energy making them super fast shards of metal zipping about inside, as compared to a single large slug of AP, ( unless of course the AP round had a large HE charge in it, but most were defective in the early war periods) that in most cases, passed right on thru the fighting compartment, causing minimal damage.
unless of course it hit a crewman or a stored round....
