Chris Kemp's Not Quite Mechanised
Italian Infantry Division
For various reasons, the Italians were not Germany's most enthusiastic allies, although they fought bravely when occasion demanded it.
The picture above shows the Blackshirt Legion in the forground and one infantry regiment behind.
J. Ellis cites no armoured divisions in Russia; 3rd (Ravenna), 5th (Cosseria), 9th (Pasubio), 52nd (Torino), 156th (Vicenza) (Jul'41-Jan'43) Infantry Divs.
They fought in Army Group South (Later Army Group B) as 8th Italian Army. Most being destroyed and withdrawn to Italy after the battles that cut off Stalingrad.
The exigencies of war would mean that very few units would exactly match their Order of Battle. Combat would quickly reduce the strength of the fighting companies down. We typically fight battles with units at 2/3 to 1/2 their authorised combat strength, so the picture above represents the norm rather than an exception. Units in contact with the enemy would also add captured equipment (especially logistic equipment ) to their inventory.
