Front (Soviet Army)

A front (Russian: фронт, front) is a military formation in some countries. Originating in the Russian Empire, it has been used by the Polish Army, the Red Army and Soviet Army, and by Turkey. It is roughly equivalent to an army group in the military of most other countries. It varies in size but in general contains three to five armies. It should not be confused with the more general usage of military front, describing a geographic area in wartime.

After the outbreak of the First World War, the Russian General Headquarters set up two Fronts: Northwestern Front, uniting forces deployed against German Empire, and Southwestern Front, uniting forces deployed against Austria-Hungary.

In August 1915, Northwestern Front was split into Northern Front and Western Front.

At the end of 1916 Romanian Front was established, which also included remnants of the Romanian army.

In April 1917, Caucasus Front was established by the reorganization of the Caucasus Army.
