Neither the Russian Empire, nor the Soviet Union ever had an organised force that could be equated to a militia. Instead a form of organisation that predated the Russian state was used during national emergencies called Narodnoe Opolcheniye (People's Regimentation). More comparable to the English Fyrd, it was a popular voluntary joining of the local полк polk, or a regiment, though it had no regular established strength or officers, these usually elected from prominent local citizens. The Tsarist regime was particularly reluctant to arm and organise militia forces because of concern over a repetition of the Pugachev Serf Revolt of the late 18th century. Only in the face of the national emergency of 1812 was the raising of "opolcheniye" "cohorts" permitted. Numbering over 223,000, loosely trained and barely equipped, these enthusiastic volunteers nevertheless provided a useful reserve for the regular army.
