Not sure what you are asking. The Elefant is not produced. It enters the game in two Heavy Panzerjager battalions. One on turn 102 and the other on turn 182. Theoretically, all of the Elefant elements will stay in the 653rd Heavy Panzerjager battalion until it withdraws on T178.
Ferdinands first saw combat in the Battle of Kursk, where eighty-nine were committed. Reputed to be able to knock out a T-34 at a range of over 3 miles with its 88mm Pak43/2 L/71, it was a strong opponent for the Allies. Although effective at destroying Soviet tanks, they performed quite poorly in other respects. In its original configuration, the Ferdinand lacked a machine gun as secondary armament, making it vulnerable to attack by infantry. While this was a disadvantage, most combat losses were from mine damage and mechanical failure. Within four days nearly half of the vehicles were out of service, mostly due to technical problems and mine damage to tracks and suspension. Combat losses to enemy action were very low as the very thick armor protected the Ferdinand from almost all Soviet antitank weaponry; in fact, most of the vehicles destroyed or captured had been abandoned by their crews after mechanical failure.
Many of these immobilized Ferdinands had to be permanently abandoned, as they proved too heavy to tow for most German recovery vehicles. Others were lost to mechanical breakdown during the retreat following the Soviet counter-offensive in the latter stages of the battle. The surviving vehicles saw further limited action on the Dniepr front during late 1943.
In Italy, March 1944
The units were deployed at a company level, sometimes sub-divided into platoons, with infantry or tanks to protect the vulnerable flanks of the vehicles. On the attack, this Jagdpanzer was a first-strike vehicle, while in defence, they often comprised a mobile reserve used to blunt enemy tank assaults.
Although the Elefant modifications improved the vehicles, some problems could never be fully fixed. In 1944 the Elefants served on the Italian front but were rendered rather ineffective, as their weight of nearly 70 tonnes did not allow them to use most Italian roads and bridges. Due to a permanent lack of spare parts most of the units were not destroyed in battle, but abandoned and blown up by their own crews. One company of Elefants saw action during the Soviets' January 1945 Vistula-Oder offensive in Poland, and the very last surviving vehicles were in combat at Zossen during the Battle of Berlin.
The Ferdinand/Elefant may have been the most successful tank destroyer employed during the war in kills per loss, reaching an average ratio of approximately 10:1. During the Battle of Kursk, the 653rd Heavy Tank Destroyer Battalion (German: schwere Panzerjäger-Abteilung, sPzJägAbt) claimed to have knocked out 320 enemy tanks, for the loss of 13 Ferdinands. This impressive average ratio was due to its extreme firepower and protection, which gave it an enormous advantage when used in head-on combat or a static defensive role. However, poor mobility and mechanical unreliability greatly diminished its operational capability
