I found in book "Military Units in Urals during Civil War" by V.V Dublennykh list of Reds formations.Reds units was formed from great number detached elements and haven't experience to July ,1918.Nevertheless in June Reds had entire Army.
I think(and suggest) that using this units(historical) (or may be whole army) with Anti-Red units from Nevyansk rebellion(for balance) makes game more interesting on initial stage of Grand Campaign
I can prove its existence by serious books and recheck every name
