German M15/42: 12th Panzer Polizei Company

After a brief period of rest and refit, the 5 SS Wiking was sent to assist in the defence of Kovel, which was under threat from a strong Soviet force. Gille led his men towards the town and began setting up a defensive perimeter, which was soon encircled by the Red Army. The II.Battalion, SS Panzer Regiment 5 Wiking, newly equipped with Panther Tanks, along with the III.Battalion, SS Panzergrenadier Regiment Germania, newly equipped and up to strength, arrived at the front from Germany and began to form a relief unit. The unit was under the command of Obersturmführer Karl Nicolussi Leck, commander of 8.Company, II.Battalion, SS Panzer Regiment 5 Wiking. Nicolussi Leck immediately launched an attack with five tanks. Soon after beginning the attack, he received a radio message from the besieged commander to halt his attack and withdraw. Nicolussi Leck ordered his radio operator to ignore the call, and continue with the attack. Risking court martial, Nicolussi-Leck proceeded to fight his way though the Red Army encirclement, destroying several tanks in the process. His Panther tank was the first vehicle to break the encirclement, for his actions he was awarded the Knight's Cross of the Iron Cross.
After the relief force had established a corridor to the trapped forces, the withdrawal began. Unlike the previous encirclement at Korsun, they managed to escape with most of their equipment intact.

The Sturmtiger made its combat debut during the Warsaw uprising. Two crews of factory engineers manned the Sturmtiger assault howitzers giving a hands-on field display of this new weapon’s capabilities. Staying well behind the lines, these two behemoths devastated city blocks with their 38cm RW61 shells from up to 4600 metres away.

Built on the chassis of a Tiger heavy tank, the Sturmtiger carried 14 rounds of the 600lb/270kg shells. Each shell contained 125 kilograms of explosives. It had one hull-mounted 7.92mm MG34 machine gun. The massive 15”/38cm rocket-assisted howitzer possessed unprecedented firepower when targeting large targets such as buildings or bridges.
