I've books on the Russian front which say "most" German tankers didn't like assult guns in almost "any" design (x-cept perhaps Erichs mention).
Most attacks against them came from the side, in ambush, from anti-tank guns.
The standard response to this was to go around them and attack them from the side. Hoping your mobility would exceed theirs in getting their guns turned & dug in again.
Almost "all" would have rather had a full rotating turret to enguage these tatgets while performing this manuver. To be specific, the Panzer IV.
The "assult guns" could not do this, and were either forced to face the threat (doing exactly what the enemy wants, in exactly the place they want it to happen), or just "take it" until you get around them. Neither was a welcome option.
I've got a good picture of a American GI (you probably all do) posing with his Bazooka next to his Hetzer victim. It put a neat little hole right in the middle of the side of the upper superstructure.
