Panzerjäger (German: literally "armor hunter", more broadly "anti-tank") is a term used for an anti-tank vehicle (self-propelled anti-tank gun), as well as anti-tank units. The term was first used in the Wehrmacht (German armed forces, 1935–45), and also post-war by the German Federal Republic Bundeswehr. The term Panzerjäger was used in the Bundeswehr as a designation of rank.
From 1940, the troops were equipped with vehicles produced by mounting an existing anti-tank gun complete with the gun shield on a tracked chassis to allow higher mobility.
The development of Panzerjägers into the fully protected armored vehicle designs began before the war with the -designated armored artillery vehicles, the initial German turretless tanks to use completely closed-in armored casemates, and continued until 1944, resulting in the fully enclosed "hunting tanks", purpose-built heavy-gun tank destroyers. These usually used upward extensions of both the glacis plate and hull sides to comprise three sides of their closed-in casemates. continued to serve as a separate branch of the Heer until the end of the war, often replacing tanks due to production shortages.
Initially, the chassis of captured light tanks were used after turrets were removed, providing a cost-effective solution to the German shortage of mobile anti-tank weapons in infantry divisions. Despite the shortcomings of light armour and high silhouette, they were successfully used in their intended role of a self-propelled anti-tank gun. Neither anti-tank guns nor Panzerjägers had any real armor to speak of, and while the had a higher silhouette and was more visible than an anti-tank gun, it was also much more mobile, and was able to relocate or retreat far more rapidly than conventional anti-tank gun crews. The lack of armor meant little until the self-propelled guns began to take on more and more of the offensive duties of tanks as the war progressed and production lagged.
From 1943, the Type 44 infantry divisions included the following divisional Panzerjäger-Abteilung ('tank hunter battalion'):
units were either assigned as the 14th companies in infantry regiments, or as a whole Abteilung (battalion) within Panzer and divisions, in both the Waffen-SS and the Heer, the (regular army). Independent battalions and regiments were used by corps to protect the most likely avenues of tank attacks, while divisions would often position their on the flanks, or use them to support infantry advances against an enemy using tanks. When used with tanks, despite intense inter-branch rivalry, would work in teams, with the tank crews enticing enemy tanks to fire, disclosing their position, and engaging the enemy from a defilade. were often called upon to provide direct high explosive supporting fire to infantry by destroying machine gun and artillery positions, particularly in urban fighting.
Designs of the vehicles varied based on the chassis used, which could be of three types:
designs that entered service included:
The later designation was used from the beginning for the following more integrally armored vehicles:
In the Bundeswehr of West Germany and subsequently the reunified Federal Republic, the Panzerjägers were reintroduced as a separate arm of the German Army. The Panzerjägertruppe existed from 1956 until 2006 when it was incorporated into the Panzer branch of the army. Among its notable systems of armament were the Jaguar 1, Jaguar 2, Kanonenjagdpanzer, Raketenjagdpanzer 1, Raketenjagdpanzer 2 and the Kampfpanzer M48A2GA2 (a 105 mm gun armed variant of the M48 Patton tank. Soldiers in the lowest rank in the Panzerjägertruppe carried the term Panzerjäger as a title of their rank.
