My Sister Forces

My initial force is based on a three company battalion and three battalion regiment.
I have built already an Independent Heavy Tank company of ten T-35 heavy tanks (models 1933 and 1938).
I then have a battalion containing a company of T-28 medium tanks (models 1935, 1938, and 1940) along with a company of BT-7 fast tanks (model 1936) and will be building a company of BT-2 fast tanks (models 1931 and 1933).
