In November 1939 the Red abolished its 4 tank corps. Why did they do this? Especially, considering that the Wehrmacht’s Panzer Divisions were instrumental in defeating the Polish forces in September 1939. For this we take a look at the broader historical context, namely the massive expansion of the Soviet Tank Arm in 1930s, the Spanish Civil War, the battles of Lake Khasan and Khalkhin Gol, the experience in Poland 1939 and other elements.
