Other forms: commissars
A commissar was a political official in a communist state or army. The political commissar, a party commissar, the commissar's report.
In the Red Army the role was to watch the officers as much as to instruct the troops, and orders needed the signature of both. The word is used loosely and hostilely now for any official enforcing a line, which is a long way from the original post.
