hello CrazyD88! I found this in achtungpanzer, was there always but only now was I interested...

here´s the important part with Ferdinands extracted:

Panzer Kompanie (Funklenk) 312 was subordinated to s.Pz.Abt 505 with 31 Tiger Is and 15 PzKpfw. IIIs during the Battle at Kursk. The only detailed combat report of Borgward IV in action at Kursk comes from Pz.Kp (Fkl) 312. "One B IV was sent out 800m towards a PaK-nest with 2-3 PaKs and detonated, destroying the guns and the accompanying infantry. Another B IV was sent 400m against a T-34/76 which was destroyed as it rammed the B IV. Three B IV were sent 400-600m towards three concrete bunkers, destroying all of them. Two B IV was sent 800m towards a PaK-nest and an infantry gun-nest, destroying both of them. Another B IV reached a Soviet position and was set on fire by a Molotov Cocktail and it exploded along with the enemy position."

Panzer Kompanie (Funklenk) 313 belonged to 2. Abteilung / s.Pz.Jäg.Rgt. 656 subordinated to s.Pz.Jäg.Abt 654 equipped with 44 Ferdinand heavy self-propelled guns. Their roll was to blow a whole through the enemy minefields enabling further advance of the Ferdinands. Before one had reached the enemy minefields, 4 Borgward IV were lost to own mines, while another 4 makes it through and are sacrificed in favor of the Ferdinands which then were able to pass through the minefield. Later on three Borgward IV destroys two AT-gun nests and single bunker. Later in action with s.Pz.Abt 508.

Panzer Kompanie (Funklenk) 314 belonged to 1. Abteilung / s.Pz.Jä.Rgt. 656 subordinated to s.Pz.Jäg.Abt 653 with 45 Ferdinand heavy self-propelled guns. It used 12 Borgward IV to blow a hole through a deep enemy minefield. StuGs which were used as control vehicles rolled through, but the engineers could not mark the passage as heavy artillery fire pinned them down. Eventually some Ferdinand crew lost track of the passage and a number of vehicles were disabled, considerably delaying the attack. Later that day, two Borgward IV were sent to a woodline hold by the enemy. After detonation there was no enemy resistance existing. Companies under Panzer Abteilung (Funklenk) 301 lost 20 Borgward IV in four days. Only 4 Borgward IV didn't reach their designated targets, either after being hit by enemy AT- or artillery-fire. Two of them were burnt out, while the other two were recovered. In general, the unit was very pleased with their performance, although the radio-control equipment was effective up to 800-1.000m instead of the desired 2.000m.
