The Comprehensive Atlas of the Eurasian War (2010 Edition) Excerpt, Soviet Mechanized Formations
The core of the Red Army's offensive striking force was it's 36 tank divisions. Evolving straight out of the more ad-hoc divisions employed during the War of the Patriotic Blood, the TO&E for the Soviet Union's first true tank division was first issued in 1930, clearly in anticipation of the first T-31 tanks, and the first such formation was formed in 1932. It's most famous, or infamous, component was it's three brigades of 65 T-31 tanks each. The heavy armor however tends to overshadow the equally vital organic infantry component from not only those organic to the tank brigade but which also came from the fourth mechanized brigade, the soldiers of both of which were first mounted in fully-enclosed P-01 armored half tracks and later in T-31 chassis repurposed as armored personnel carriers, and it's regiment of 63 self-propelled armored guns and 8 rocket artillery pieces. All of these elements were the core made the Soviet tank division a true combined arms force capable of smashing through enemy lines, exploiting deep to seize key objectives, beating off counter attacks, and together with the division's support service component they remained virtually unchanged throughout the war.
The main changes came in the division's composition of light/medium and superheavy armor, as the Soviets steadily phased out their aging force of light/medium tanks in the early war through the simple expedient of expending them in battle. Later, each tank division steadily received a regiment of 21 IS super-heavy tanks which gave them a potent linebreaker spearhead for the breakthrough phase. When support personnel are included, the manpower component of the division constituted 16,770 soldiers. The majority of Soviet tank divisions were placed under the control of the 8 tank armies formed during the war, with the standard average being three divisions to each tank army. However, the remaining ten were generally attached to the combined arms armies on a as-needed basis for shallower exploitation.
In addition, the Soviets continued to use up to 62 independent tank brigades throughout the war. Each one was directly assigned to a combined-arms armies primarily to provide armored support for the infantry and were not used as a independent force.

The Comprehensive Atlas of the Eurasian War (2010 Edition) Excerpt, Soviet Artillery Formations
Of course, like all of the Eurasian War combatants, the Soviets had artillery units organic to their divisions, with the D-30 85mm and later BS-3 100mm field guns still fondly remembered by Soviet veterans too this day. And, like all of the Eurasian War combatants, they amassed a plethora of independent artillery battalions, regiments, and brigades that could quickly be attached and detached in support of the infantry and armor by corps, army, and front (army group) level commands. But unique to all of the Eurasian War combatants, the Soviets were the only ones to create independent artillery divisions outfitted hundreds of mortars, guns, and/or rocket launchers each that gave the front-level Soviet commanders truly massive quantities of firepower. It is commonly believed that this unique attitude towards artillery was a result of experience in the War of the Patriotic Blood where Soviet artillery had played a key role, debatably above even that of the armor and infantry, in defeating Drakian forces.
The 48 artillery divisions were the more common. Constituting one brigade of 85mm (and later 100mm) field guns, one brigade of 122mm howitzers, one brigade of 152mm gun-howitzer, a brigade of 120mm heavy mortars, and a regiment of 203mm howitzers for a total of 220 guns and 144 mortars. A late-war evolution was the attachment of a rocket artillery regiment of 36 "Katyusha" Rockets. The personnel in these divisions, at 10,296 including divisional support personnel, represented the finest artillerists in the Red Army and they were renowned for their flexibility in the planning and execution of their fireplans and even in impromptu fires proved quite responsive, often coordinating closely with spotter aircraft from the VVS. And, as always, acknowledgement must be given to the incredibly light weight of Soviet artillery pieces given their caliber, long believed to be the result of incorporating the supermaterial Stalinium in the design of the gun.
The 24 rocket divisions made up the other component of Soviet artillery formations, with the three brigades of large caliber "Katyushas" amount to an astounding 1,068 multiple-rocket launchers. It's been observed, with only slight hyperbole, that a single rocket division could reduce a multi-square kilometer stretch of territory into a image of the meteor pockmarked moon. Particularly feared, however, was the ability of these rockets to deliver chemical weapons, above all the dreaded "Comrade Grey", due to their saturation effect. However, the tremendous supply requirements of the division made these formations the largest divisional-elements in the Red Army at 24,184 men each, much of whom were support personnel dedicated to ensuring the rockets could keep firing. Later in the Eurasian War, the rocket divisions also semi-infrequently obtained a regiment of 8 towed ballistic missile launchers, as the Soviets experimented with integrating tactical ballistic missile strikes against key fixed targets with as part of their offensives.
Organized into artillery corps of 4 artillery and 2 rocket divisions, each Soviet front generally disposed of two corps. When concentrated on key sectors of the front, the resulting deluge of shells and rockets could be so devastating that sometimes the preliminary bombardments from these forces alone managed to break enemy defenses even before the main infantry-tank assaults began.
