Panzerjäger (German "armour-hunters" or "anti-tank troop", abbreviated to Pz.Jg. in German) was a branch of service of the German Wehrmacht during the Second World War. It was an anti-tank arm-of-service that operated self-propelled anti-tank artillery, also named Panzerjäger. Soldiers assigned to tank hunting units wore ordinary field-gray uniforms rather than the black of the Panzer troops, while Panzerjäger vehicle crews wore the Panzer jacket in field gray. Development From 1940, the Panzerjäger 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 Jagdpanzer armored vehicle designs began before the war with the Sturmgeschütz-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 Jagdpanzer "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. Panzerjäger 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 Panzerjäger 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. Organisation From 1943, the Type 44 infantry divisions included the following divisional Panzerjäger-Abteilung ('tank hunter battalion'): Staff company (Stabskompanie) 1. Panzerjäger-Kompanie equipped with 9-12 towed Anti-tank guns 2. Sturmgestchütz-Batterie equipped with ten fully-casemated StuG III, StuG IV assault guns or Hetzer vehicles 3. Light anti-aircraft company (leichte FlaK-Kompanie) equipped with 12 towed 20 mm FlaK autocannon Combat use Panzerjäger units were either assigned as the 14th companies in infantry regiments, or as a whole Abteilung (battalion) within Panzer and Panzergrenadier
