  This mech corps has 20 KV-I and T-34 tanks but I don’t know the exact
  composition or placement of them.  They should be part of the 48th or 51st
  Tank Divisions.
  About 150 light tanks listed for this
  division.  They would be some mix
  of these two types, but mostly T-26.

  On June 22, 1941, the 23rd Mech Corps was stationed in the interior at Odessa. In early July the
  corps was ordered to the front and engaged the Germans on the 9th of July. The corps was largely
  destroyed after a couple of weeks.
