 Mechanised Divisions were formed during 1945–46, and then all remaining Rifle Divisions were converted to Motor Rifle Divisions in 1957.Many infantry (pekhotniye), literally 'movement', and rifle (strelkoviye), literally 'sharpshooter', divisions were inherited by the Workers-Peasants Army from the former Imperial Russian Army, but were renamed in the spirit of the Revolutionary times, often with names including words such as "Proletariat", "workers and peasants", or other titles that differentiated them from the past.They employed some of the 48,000 former Tsarist officers and 214,000 Tsarist NCOs along with over 10,000 administrative personnel.
