> Damn, at that point they should have added machine guns to the sides of the turret, just so that the loaders can have their fun if they are surrounded by infantry.
Not quite like that, but it had an extra machine gun.
It was a hybrid of breakthrough tank and SPG.
A breakthrough tank is not supposed to get bogged down, but exactly because it runs ahead is not escorted by infantry, and needs to suppress in both directions while crossing trenches. Which was one of the reasons for those monsters with multiple turrets.
KV-1 had 3 machineguns: driver, coaxial and ball mount in the rear of turret. So when the turret is turned sideways, coaxial MG can suppress on one side, ball mount MG on the other.
KV-2 turret (sloped forward armor, bolted gun service hatch plate extending to the beveled rear corners) had firing ports.
turret (boxy one >>59103
with flat ammunition hatch) had coaxial and rear mounts again, though the rear mount is not always as visible as the bump on KV-1. And seems to be optional, in that on some photo it’s absent or removed, but then for use as SPG it’s unnecessary anyway.
