This may sound dumb. But what is a penal battalion
the penal battalion accounted for only 1.4% of the total number of Red Army. Don't you think that the 1.4% is not enough to win the war alone the penal battalion?...the penal battalion were ONLY (!!!) to officers, has committed any of the offences. Ranks from lieutenant to colonel.Criminals, privates and sergeants sent in separate penal COMPANIES. The difference is significant....
P.S. - I used Google translate
