Short answers, pulled from the story.
Field Marshal Fedor von Bock commanded Army Group Center as it prepared to strike from Poland on the 22nd of June 1941. The Wehrmacht's armored forces included Hoth's 3rd Panzer Group and Guderian's 2nd Panzer Group alongside nine infantry divisions.
Seven days after the invasion began on the 29th of June the pincers of Guderian's and Hoth's groups closed east of Minsk. By the 30th of June the pocket was completely closed after a second Red Army counter-attack by the 20th Mechanized Corps failed to breach the encirclement.
Soviet divisions possessed 4,522 total tanks with 592 being T-34 or KV models while German corps fielded 1,936 total tanks including non-combat commander vehicles and outdated models like the Panzer I and II. This stark numerical difference existed over the entire area of the Soviet Western Front on the 22nd of June 1941.
The NKVD executed Pavlov and his staff for cowardice and failure to perform their duties during the campaign following their recall to Moscow. Their families suffered repression as part of the political fallout from the military disaster although all three generals involved in the command structure were pardoned in 1956 long after the war ended.
Soviet doctrine demanded an aggressive counterattack into German-occupied Poland rather than a defensive war of attrition which created weak flanks due to the demarcation line established after the division of Poland in 1939. Both sides positioned their forward troops in a double-bulge formation that invited a pincer movement.
