Red Army concentration of force

In a lecture to The Dole Institute of Politics, Dr. Jonathon House explains How the Red Army Defeated Germany: The Three Alibis.

In the lecture he talks about Red Army doctrine that used deception and concentration of force to achieve localised overwhelming force of numbers.

In Operation Bagration

185 Red Army divisions comprising 2.3 million soldiers and 4,000 tanks and assault guns smashed into the German positions on a front of 200 km. The 800,000-strong Army Group Centre was crushed.

House explains that on a five mile wide front, the Red Army concentrated five divisions and a separate tank brigade against one German division. There were four other places along the front with similar force ratios.

This came after the Red Army had fooled the Germans into believing an attack would come further south, causing the Germans to  move forces south.
