Generalfeldmarschall zur Luftschiff Abteilung
Those numbers were a quick overview.There are two types of information being used here.
The Figures for personnel are just for the Germans.
The Figures for material a combined total of German and Italian. For instance the Germans may only have shipped 1434 tanks to North Africa, Now maybe the Germans lost around 1100 armored cars, sp guns and armored 1/2 tracks or perhaps hundreds of Italian tanks are included in the total?
The Italians did loose 10s of thousands of truck and the vast majority of the shipping was Italian.
Of the German tanks sent to North Africa 54 were Pz 1s, 177 were Pz IIs, 832 were Pz IIIs (a small number still had 37mm guns), 307 were Pz IVs and 31 were Tigers. 33 were command tanks (?).
Another source claims that the Germans lost 240 Pz II, III, IV tanks in NA from June 1941 through Dec. Germans lost total, on both fronts over 3300 tanks/tank chassis vehicles of all types during that time period. A number of the vehicles lost in Russia were salvaged/rebuilt. What the German workshop units in the NA were able to do I don't know. They did some work but compared to shipping tanks back to the factories it was not as much and their is a difference between break downs and combat damage.
I still don't have my books ot computers to give a solid breakdown.
Here's a good overview of the MTO with numbers:
GI -- World War II Commemoration
This page also brings up a good point, too: the large amount of German manpower and equipment used to fight the Allies in Italy itself.
So in the end, Italy cost Germany a considerable amount of assets that could have been used to both fortify Europe as well as fighting the Soviet Union.
