Soon, the 502 heavy tank destroyer battalion of Ryan sent technicians and maintenance personnel to classify and take over these Soviet tanks. This is the first time that the German army captured Soviet tanks on a large scale. These tanks must also be handed over to the technical department to analyze the design characteristics and technical parameters of Soviet tanks. Ryan''s defense line was soon taken over by the 2nd regiment of the 3rd SS armored division. He was ordered to follow his battalion close to the original Soviet German border. In the afternoon of that day, the battalion of 502 battalion had already crossed the Soviet German border and became the first German armored force to enter the Soviet territory for counterattack. In the early morning of April 8, the German army began to fight back against the Soviet border forces. After the start of the Soviet German war, the Soviet Union''s attack on the German defense was reversed, and the German army began to fight back on the long border. Everyone did not expect that the German Army started a crazy counterattack before it completely digested the Soviet troops in the encirclement. From the moment the German army crossed the border, Khrushchev issued the highest order of "no retreat, start counterattack immediately".
