IMHO this game is incomplete without the reflection of the Guards units.
"The title of the Soviet Guards was first introduced on September 18, 1941 in accordance with the decision of the Headquarters of the Supreme Commander-in-Chief (Stavka Verkhovnogo Glavnokomanduyuschego) and by the order №308 of the People's Commissar of Defense for the distinguished services during the Yelnya Offensive. The 100th, 127th, 153rd and 161st Rifle Divisions were renamed into the 1st, 2nd, 3rd and 4th Guards Divisions, respectively. The Soviet 316th Rifle Division was renamed to the 8th Guards Rifle Division on November 18, 1941, following the actions of the Panfilovtsy and was given the Panfilovskaya title in honor of its late commander Ivan Panfilov. By December 31, 1941 the 107th, 120th, 64th, 316th, 78th, and 52nd Rifle Divisions had become the 5th through 10th Guards Rifle Divisions."
