My primary source of the units involved in the Battle of Orel is Seargent Magazine #5, which was available for a while on the web. Note that the Soviets refered to it as the Orel-Kromy Operation.
The units listed are part of the Southern Front, under KomFront A. I. Egorov.
The spear of the Soviet attack was the Shock Group, led by the Latvian Division. It was originally part of 13th Army, but transferred to 14th Army during the operation as the 13th Army started to disintegrate.
Commander – A.A. Martusevich (from 20 October – F.K. Kalnins)
The Latvians were the best forces in the Red Army at this battle, both experienced and motivated. They were to bear the brunt of the fighting at Orel. Their main fault was that they were quite slow moving, due to excessive caution.

This brigade appears to have been part of the newly formed "Cavalry Division of the 14th Army" at this time, but fought separately from the other two brigades (in 14th Army) at Orel-Kromy. It would later be named the 8th Red Cossack Cavalry Division.
The brigade was raised in the Ukraine, and the "Cossack" of the title refers to this, not any reference to the usual Cossack Hosts. It was an experienced and well-equipped unit, and was very much the spear of the Red attacks.
"Chervonno" is the colour red (but a different word from that used for Red Army).

Commander – Ya. Pal'vadre
7,191 men: 3,346 bayonets, 114 sabres, 68 HMGs, 12 LMGs, 11 guns
This division was previously known as the Composite Division. The Estonian integral cavalry regiment had been sent to the NW Front.
The quality of the Estonians was high, similar to the Latvians, and they fought well during the battle.
1st to 4th Estonian Rifle Regiments
1st All-Training Regiment (former Putilov Factory workers)
86th Rifle Regiment
400 sabres?
probably about 4 cars
At least 5 trains.
The 13th Army had 13 operational trains in May 1919, but lost most of these in their retreat. Some reinforcements arrived from reserve in October however.
Commander – I.P. Uborevich
Chief of Staff – S.G.Szhvarelidze-Bezhanov

5,520 bayonets, 690 sabres, 122 MGs, 52 guns (at 10 October)
361st to 369th Rifle Regiments
three other regiments ?
If the 41RD followed the usual pattern, it would have only the 121st to 123rd Rifle Brigades. However it seems to have had four brigades. Presumably the fourth was not numbered in sequence, but added as a result of a merger of another unit. It was likely only temporary.
Commander – A.N. Lengovsky
7,015 bayonets, 245 sabres, 224 MGs, 23 guns (at 1 October)
It appears this division took little part in the Orel-Kromy Operation.
406th to 414th Rifle Regiments (in the 136th to 138th Rifle Brigades)
Commander – N.A. Khudyakov (from 11 October – F.A. Kuznetsov)
1,303 bayonets, 200 sabres, 40 MGs, 12 guns (at 8 October)
It seems this division only took a peripheral part in the Orel-Kromy Operation.
505th to 513th Rifle Regiments (in the 169th to 171st Rifle Brigades)
Commander – Yu. V. Sablin
The composition of this group is unknown. It appears it took no active part in the Orel-Kromy Operation.
Commander – N.K. Shchelokov (acting)
Although formally grouped together, it seems these units fought separately at this time. The Chervonno Cossacks took an active part in the Orel-Kromy Operation as part of the Shock Group, but it is not clear that the other two brigades took any part at all.
Chervonno Cossack Brigade (detached, with the Shock Group)

probably about 4 cars
The 14th Army had lost most of these in their retreat.
