Despite its very young industry, the USSR was focused on building a large amount of tanks right off the bat. It might seem weird to focus on something like that so early on, but once you see the intelligence information at the army's disposal then everything falls into place.
This map maps the tank armies of European nations by the fall of 1931 (according to German sources). The data is as follows:

In retrospect, of course, this map is terribly wrong. There were hardly hordes of French superheavy tanks wandering around in Europe, but that was the boogeyman of the time. 20 years later you see the exact same thing with IS-3 tanks reported everywhere in Korea, for instance.
