This is an injection-plastic military vehicle model kit.
From the manufacturer:
The Opel Blitz medium truck was used extensively by the German Army on all fronts during World War Two. Several thousand of them were produced. They were also used as platforms for anti-aircraft weaponry, and tanker, workshop and ambulance versions were made. Of sturdy construction and easy to maintain, it also featured good off-road performance which made it invaluable in both the Russian and African campaigns.
Will be roughly 8.3cm long when completed; includes decals for 3 versions (British Army, Normandy, June 1944; U.S. Marines, Iwo Jima, 1945, and U.S. Army, Germany, 1945).
