During World War II, the German Army widely used self-propelled anti-tank guns. There were two categories of these vehicles: the so-called Panzerjäger (tank hunter) which had an open casemate so the crew was fully exposed from above and was provided with thin front and side armor protection, and the Jagdpanzer (tank destroyer) with a closed casemate so the crew-members could travel and fight safely. This book, which includes several color profiles and period photographs, is focused on the equipment of the German anti-tank units.
