In early 1942 the Red Army began to field new Tank Brigades, each of which included one Motor Rifle-Machine Gun Battalion. In late 1943 the unit was retitled a Motor Submachine Gun Battalion and rearmed accordingly. The Motor Rifle-MG and Motor SMG Battalions were particular to Tank Brigades, while the Motorised Rifle Battalions were a different type of unit found in Motorised or Mechanised Brigades.
For the purposes of this study the evolution of the Motor Rifle-MG and Motor SMG Battalion can be divided into three stages;
1. The Motor Rifle-MG Battalion in its initial form, as authorised in February 1942.
2. The first minor revisions of July 1942, with more substantial amendments being made by June 1943.
3. The final organization of November 1943, which brought the Brigade’s previously separate Anti-tank units into the Battalion, which was now reorganized and re-equipped as a Motor Submachine Gun Battalion.
Below are links to the files that make up this study. The first is a narrative of the Battalion organization and how it evolved between 1942 and 1945. There are then separate files detailing in full the information as found in the штат, or Shtat (State) for the unit concerned, which gave the authorised numbers of personnel, transport and weapons for the unit at full strength.
