Panzerjäger units were either assigned as the 14th companies in infantry regiments, or as a whole Abteilung (battalion) within Panzer and Panzergrenadier divisions, in both the SS and the Heer (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 Panzerjäger on the flanks, or use them to support infantry advances against an enemy using tanks. When used with tanks, despite intense inter-branch rivalry, Panzerjäger would work in teams, with the tank crews enticing enemy tanks to fire, disclosing their position, and Panzerjäger engaging the enemy from a defilade.
