The prewar chain of command was: military district, corps (or Army corps), then to division, brigade, regiment, and then the regiment's battalions.

After mobilisation in the event of war the chain of command of the Imperial Russian Army ran from Stavka, the Russian general headquarters, which was created during mobilization, to Front-level (Army group) also created during mobilization, to the Army level. Army headquarters were created during mobilization by transformation of the military district headquarters. Below Army level the chain was the same as in peace-time; corps (or Army corps (terms used interchangeably), division, brigade, and regiment.
