The Reserve Front describes either of two distinct organizations during the war. The first version was created on July 30, 1941 in a reorganization of the earlier Front of Reserve Armies. STAVKA Order No.003334, of 14 July, directed that the Front of Reserve Armies include:
- 24th Army, with ten divisions, three gun, one howitzer, and three corps artillery regiments, and four anti-tank artillery regiments;
- 28th Army, with nine divisions, one gun, one howitzer, and four corps artillery regiments, and four anti-tank artillery regiments;
- 29th Army, with five divisions, five regiments of artillery, and two regiments and one squadron of aviation;
- 30th Army, with five divisions, one corps artillery regiment, and two AA artillery regiments;
- 31st Army, with six divisions, one corps artillery regiment, and two anti-tank artillery regiments; and
- 32nd Army, with seven divisions (apparently including the 8th Rifle Division), and one anti-tank artillery regiment.
This Front was encircled and destroyed at Vyazma.
The second version of this Front was created on April 6, 1943. It incorporated the:
- 2nd Reserve Army (3rd Formation)
- 24th Army
- 53rd Army
- 66th Army
- 47th Army
- 46th Army
- 5th Guards Tank Army
- eight mobile corps
It was reorganized as the Steppe Military District on April 15, 1943 and eventually designated the Steppe Front.
