Following the failure of the Kursk offensive, the German Army fought on the
defensive, first on the Eastern Front, then in Italy and on the Western Front. The
nature of warfare had changed again after the victorious years, and the German
Army adapted to meet the new requirements. Even the Panzerwaffe, the German
armoured force that once spearheaded the blitzkrieg campaigns, changed its
methods of operation. In turn, the role of the Panzer Divisions changed, as they
found themselves called upon to fight defensive battles. No longer were there
armoured thrusts into enemy territory; those that did happen served only to
relieve encircled units and allow them to escape. Tank battles were now mainly
fought to prevent the enemy from breaking through the German defence lines.
Furthermore, since late 1943 the Panzer Divisions of the Heer (Army) no longer
represented the sole component of the Panzerwaffe; new Waffen-SS Panzer
Divisions were upgraded or raised, while small armoured units, like the heavy
Tiger tank battalions, acquired greater importance.
