Sturmpanzer IV Brummbar (SdKfz 166, Sturmgeschutz IV fur 15cm StuH 43) was a German self-propelled assault gun. Work on the design began in 1942 with a goal of creating a vehicle well suited for the demands of urban warfare. The gun was based on the PzKpfw IV Ausf. E and F and, later, Ausf. G. Initially, the vehicle carried 15 cm StuH 43 howitzer, which was later replaced by a bespoke 15 cm StuH 23/1 L/12 weapon. Brummbar went into production in 1943.

Sd.Kfz. 173 Jagdpanther is a German tank destroyer developed by Krupp and Daimler-Benz. The order was placed in August 1943 and the vehicle entered service in the first months of 1944. It was armed with a very effective anti-tank tank gun. PaK 43 cal. 88 mm. The destroyer's combat compartment was armoured with 40 to 100 mm thick (front plate) armour plates. From January 1944, 415 pieces were produced (at the MIAG, MNH and MBA factories). The vehicle was based on the chassis of the Panther Ausf. G, but it didn't have as many technical problems as the mentioned tank. Due to the favourable power-to-weight ratio, Jagdpanther had good performance and maneuverability. Together with a powerful cannon, which was able to destroy any allied armoured vehicle that time, it made it an extremely effective and dangerous destroyer. Vehicles were used by independent tank destroyer battalions. Jagdpanthers debuted in Normandy in 1944 (within 555th and 654th Panzerjagerabteilung), achieving great successes. Also during the offensive in the Ardennes, the Allies took a toll on them. They appeared on the Eastern Front in the autumn of 1944, effectively fighting all Soviet armoured guns and heavy tanks, including IS-2. The vehicle was produced in two main variants. The early version - designated as G1 - had a smaller yoke that was welded to the hull, a modified engine compartment from the Panther Ausf. A and two driver's visors. In the later version - G2 - the Panther Ausf. G engine compartment was used, one driver's visor and a larger yoke which was bolted to the front plate with screws. There were also many hybrid variants combining the features of both versions. Until September 1944, Jagdpanthers were covered with Zimmerit in the form of characteristic squares, and not the more popular "snakes". Jagdpanthers proved to be the most effective German tank destroyers, but they appeared too late and in too few numbers to significantly influence the course of the war.
