. "German encounter of Soviet T-34 and KV tanks"@en . "Prior to the invasion of the Soviet Union during World War II, the German armed forces were not aware of two newly developed Soviet tanks, the T-34 and KV. As a result they were surprised when they met them in combat in June 1941. The German's standard anti-tank weapons were found ineffective against these new Soviet tanks. This experience prompted a notable leap in tank development in Nazi Germany, mainly in an effort to counter these new threats. By June 22, 1941, the Red Army deployed almost 1,000 T-34 and over 500 KV tanks, concentrating them into five of their twenty-nine mechanized corps."@en . . . .
