These tanks would be used in battle; including at least one operated by Hungarian Tank Ace Lt. Ervin Tarczay (credited with 10 kills during his career). These Tiger tanks were provided by the 503rd Heavy Panzer Battalion along with other armour including Panzer IV and Panther tanks; they were provided to bolster the Hungarian unit(s).
