Special attention was dedicated to the Praga-Wilson gearbox and turning mechanisms. Testers pointed out a high quality of production. Interestingly enough, the specialists here also got the mass wrong, evaluating it at 14 tons. The next stage of the study took place at the proving grounds at Kubinka, where a tank with turret number 44 was sent. The muffler mounts a special attachment that held a hose from a towed fuel tank The engine compartment was also poorly protected from Molotov cocktails. Weak points were described, which included the engine deck and the drive wheel, which jammed often on impact.

The conclusion drawn was that existing armament is enough to combat this vehicle.ДЄ fairly detailed description of the tank was composed, although its mass was overestimated at 18-20 tons. Shooting at the front plate from 500 meters with the 45 mm gun resulted in one ricochet from the applique armour, leaving a dent and a crack. It turned out that the tank was impervious to the B-39 bullet from 300 meters, but the BS-41 bullet penetrated the side in all cases. The tank was fired upon by Rukavishnikov's anti-tank rifle. In addition to the PzIV (listed as В«medium tank type IV model 1937), a Pz38(t) Ausf. In addition, the Military Council of the Western Front decided to study the German tanks on their own. The study of the Sd.Kfz.223 resulted in the creation of a new class of armoured car to replace the BA-20.

The history of the Soviet BA-64 armoured car starts here, as German Sd.Kfz.222 and 223 armoured cars were among the trophies. One tank of each type was sent to the proving grounds at Kubinka for study. The Red Star and other newspapers published photographs of destroyed German vehicles. Having taken a great number of losses towards the end of June, the division was forced to retreat, abandoning 30-40 tanks. Nevertheless, the 20th Tank Division took a beating. This explains the greater losses suffered by the Soviets. Even though the 107th Tank Division had KV-1 and T-34 tanks, the main force was composed of T-26 and BT tanks. The qualitative advantage was on the German side. They were opposed by the Soviet 107th and later 102nd Tank Divisions. The 643rd Tank Destroyer Battalion, armed with Panzerjager I tank destroyers, fought beside them. The German 20th Tank Division that fought here was armed with PzII tanks (mostly Ausf. Fierce battles for the Krapivnya village in Smolensk oblast began on July 23rd. Soviet specialists got the chance to get a closer look in early August of 1941. Captured Pz38(t) from the 20th Tank Division, September 1941
