Hybrid  or normal early Tiger?

Sturmpanzer IV “Brummbär”

The initial plans for the Brummbär were shown to Hitler in October 1942; he liked the concept and demanded they be put into production as soon as possible. The first 40 were in production by April 1943.

Brummbär first saw combat during the battle of Kursk with Sturmpanzerabteilung 216. Later 217, 218 and 219 Sturmpanzer-abteilungs were formed with the Brummbär. The Brummbär continued in production until the end of the war and saw service on the Western, Eastern and Italian fronts.
