The Pz.Kpfw. IV Ausf. H and Pz.Kpfw. IV Ausf. J tanks were produced in
the largest numbers in the range known as Sonderkraftfahrzeug 161 in
German terminology - 7,000 vehicles. This means that significant
quantities of these vehicles were delivered to units from late Spring
1943 in case of the Ausf. H and from Summer 1944 as far as the Ausf. J
is concerned. They fought on every front of the war. In addition to the
Germans, as will be described in this book, other Axis forces also used
of both types of these tanks.
