So, the soviets had the best doctrine prior to the purges?
also tank general I guess

The purges along with the (erroneous) lessons learned in the Winter War; an emphasis on overcoming fortified lines, and in Spain and Poland; the disbanding of Tank Corps with the deep strike role reassigned to the cavalry.
They were in the process of rectifying these and forming new Mechanized Corps and Tank Divisions when the Germans invaded.
Probably, but the effectiveness of Germany's Blitzkrieg points to superior armored tactics against the other countries and Barbarossa started out very bad for the Russians until they got their collective shit into their red commie sock and kicked ass.
