This is a tropical military rucksack. I do not know the country of origin or if it is from the war. It was bought in Schweinfurt, Germany. Bag is made from heavy canvas. Has canvas shoulder straps with metal tips and hooked catch on right side. Top cinches shut with rope pull and has flap with leather pull and roller buckle. It has a single compartment which measures 18x22". Only marking I found is on the metal shoulder strap tab, "XDT". Overall it is in good condition. There are a few stains and some of the rivets are missing from the shoulder straps.
