WWII In Colour

Other references I have seen on the interweb suggest that these Panzer IV tanks are of the Afrika Corps and are offloading in Triploi.

Panzerkampfwagen III Ausf N medium tanks are unloaded form a transport. After Operation Torch landed 225,000 Allied soldiers in North Africa, the Germans and Italians built up their forces. During November 1942 transports brought to the ports of Tunis and Bizerte 176 tanks, 131 artillery pieces, 1,152 vehicles, and 13,000 tons of supplies. Schwere Panzer-Abteilung 501 (Heavy Tank Battalion 501) arrived in Tunisia between November 23, 1942 and early January 1943. To assist their Tiger Is with reconnaissance and anti-infantry duties, the Panzer III ausf Ns (Sturmpanzer IIIs) were sent along. Their 75mm short-barrelled guns were excellent infantry support weapons, and their speed and reliability rendered effective assistance to the high-maintenance Tigers.
