Despite the poor roads, the Germans were ready to rely on their Mittlere Kübel-Personenwagen (medium car) Kfz.12 Adler (3 Gd) "Geländewagen", a precursor to modern-day SUVs. Following up a report of the enemy in the direction of Lake Jelettijärvi, the squad from Gebirgsjäger-Regiment 139 / 3.Gebirgs-Division shown here is trying to tow a desperately needed anti-tank gun to the front near Louhi on 15 May 1942. The Finnish hinterlands were to prove a poor operating theatre for the Wehrmacht’s advanced war machinery, designed for more accessible fronts.
