The 3.7 cm PaK 36 (Panzerabwehrkanone 36) is a German 37mm anti-tank gun. It was developed in the 1920s by the Rheinmetall concern, it entered service in 1928. In 1936 it received the designation Pak 35/36. Under the designation of 3.7 cm KwK 36 L45, it was mounted in the Pz.Kpfw III Ausf tanks. AG. At the time of its entry into the German army, it was a very modern weapon. However, over the years, its quality and effectiveness against new tanks decreased. The gun turned out to be weak during the September campaign, and during the "Blitz" in the West in 1940 it was completely useless against many Allied tanks. For this reason, it gained the unflattering nickname "door knocker". However, it survived in the German army until the operation "Barbarossa" and fought against the T-34 and KW-1, showing its utter uselessness. From 1941, it was systematically replaced by the Pak 38. Technical data: range: 7000 m, caliber: 37 mm, combat weight: 328 kg, initial velocity: 762 m / s, rate of fire: 13 spins / min.
Sd.Kfz. 10 (it. Sonderkraftfahrzeug 10) was a German light half-track transporter from the Second World War. The first prototypes were built in 1934, and mass production was carried out in 1939-1945, ending with the production of about 17,000 copies of this vehicle. The drive was provided by a single engine Maybach HL 38 TRKM or Maybach HL42 TRKM with 82 HP. Sd.Kfz. 11 did not have fixed armament as standard.
Sd.Kfz. 10 was designed at Demag AG as a light artillery tractor, and work on it began in 1932. However, due to problems with the selection of an appropriate drive unit, serial production did not start until 1939. During the service of Sd.Kfz. 10 was most often used to tow anti-tank guns (PaK 36 or PaK 40) or Nebelwerfer missile launchers. Based on the basic version of the Sd.Kfz. 10, several specialized versions were created. One of them was Sd.Kfz. 10/4, which served as a self-propelled anti-aircraft gun armed with a 20mm FlaK 30 gun. Sd.Kfz cars. 10 were used on all fronts of World War II in the period 1939-1945.
