Tiger I (1942–1945)
Tiger II (1944–1945)
The 503rd Heavy Panzer Battalion (abbreviated s.Pz.Abt. 503) was a German heavy Panzer Abteilung (a battalion-sized unit) equipped with Tiger I tanks and Panzer IIIs. In 1944, it was re-equipped with the new Tiger II. The battalion saw action on the Eastern and Western Fronts during World War II. As with other German Heavy Panzer Detachments, it was normally not assigned to a single corps, but shuffled around according to war circumstances. Later the battalion became part of the newly formed Panzer Corps Feldherrnhalle as the Feldherrnhalle Heavy Tank Battalion.

The unit was created on May 4, 1942. The unit consisted of 45 Tiger Is on May 10, 1943. In the aftermath of the Battle of Stalingrad, the battalion was deployed to Army Group Don and arrived at the front on January 1, 1943. The battalion, along with several divisions of the 4th Panzer Army, was tasked with securing the withdrawal of Army Group A; it then retreated to Rostov. On February 11, 1943, the unit was transferred to Kharkov. It took part in the Third Battle of Kharkov and the Operation Citadel in 1943. Four days before the start of Citadel, the battalion reported that 42 of their 45 Tiger tanks were operational. The unit losing three Tigers during the operation and five more during the subsequent retreat.
In January 1944, the battalion, together with a panzer regiment and infantry units, formed Panzer Regiment Bäke. The regiment was part of the relief force, which tried to unsuccessfully break through to encircled forces in the Korsun Pocket. The battalion was then trapped in Hube's Pocket. In late April 1944, the regiment was dissolved and sent West for refitting and equipped with 45 new Tiger IIs.
With the Invasion of Normandy on June 6, 1944, the unit was transferred to the command of 5th Panzer Army. On the launch of Operation Goodwood, the 3rd company, which was based in Cagny, was destroyed in the preliminary Allied bombing, with impacts powerful enough to turn a 56-ton Tiger upside down. Only one Tiger was operational at the end of the day. During the first day of Goodwood, the unit reported the loss of thirteen tanks. At the end of July, the 3rd company received new Tiger II tanks, which were subsequently destroyed in the Allied aerial attacks, with only two brought back to Germany.
In September 1944, the refitted 503rd took part in the Battle of Debrecen. In early-November, the battalion provided a mobile reserve for the 6th Army (Wehrmacht), re-designated as Army Group Hermann Balck. By mid-December, the German forces had been pushed back to Budapest. The unit took part in several failed attempts to relieve Budapest, codenamed Operation Konrad.Clemens-Heinrich Graf von Kageneck (July 1943 – 30 January 1944)
