The Jagdpanthers were intended to be deployed in battalion sized units to blunt the enemy's tank attacks.
First issued to the 559th and 654th Panzerjägerabteilungen in June 1944. They were also issued, starting in January 1945, to seven different Panzer Divisions, a Panzer brigade, and the Führer Grenadier Division.
A battalion was designated to have 30 Jagdpanthers.
The 654th was only unit in the west in June 1944. On June 6, 1944, it was at the Mailly-le-Camp training ground, near Paris. The crews had just received their Jagdpanthers. By June 18, only two companies received their complement of fourteen Jagdpanthers. Only the 2nd Company fought in Normandy, not arriving until July 28, 1944.
The 2nd was crucial in the stopping of Operation "Bluecoat", that was launched by the British XXX Corps. Just south of Caumont, the British 15th Scottish Division, with support from the 6th Guards Tank Brigade, went through the weakened German lines towards Hill 309. Three Jagdpanthers attacked the Churchills, and in two minutes, eleven Churchills were knocked out. The Jagdpanthers then withdrew because of the superior numbers of Allied tanks.
Only two of the 2nd Company's vehicles made it back across the River Seine.
51 Jagdpanthers were assigned to the offensive in the Ardennes. Typically for each of the independent army heavy anti-tank battalions, there was 1 company of Jagdpanthers and the other two had field assault guns or Jagdpanzer IV/70s. Six of these battalions were used.
The 560th Army Heavy Anti-tank Battalion, with 25 Jagdpanthers and 25 Jagdpanzer IV/70(V)s provided support to the 12th SS Panzer Division Hitlerjugend.
During the Ardennes offensive the 654th Army Heavy Anti-tank Battalion was taken from reserve and redeployed to Alsace-Lorraine on December 31, 1944. The goal of the offensive was to retake Strasbourg in a pincer attack. There were eight Jagdpanthers with the 654th and advanced with the southern pincer.
On February 6, 1945, at Wolfgantzen, near Colmar, a Jagdpanther was waiting in ambush. However, Sherman tanks from the 1st French Army succeeded in surprising it, and shot off it's tracks. Engine failure and damaged tracks forced crews to abandon two Jagdpanthers. A fourth was recovered with a Bergepanther.
By the end of the offensive there were only four Jagdpanthers in the 654th. By March 1945, the battalion was completely destroyed.
