Picture heavy "wordpress" article on the topic of clearing up” WWII battlefields after the war.... (From February 20th 2017) Cleaning up after WWII Although the intro includes efforts to recover equipment from battlefields also during the war i.e. "One of the reasons WWII battlefields did not remain littered with vehicles for long was that, with the lone exception of the USA, all of the major warring powers made some official level of combat usage of captured enemy arms during WWII. The most formal was Germany’s Beutewaffe (literally, ‘booty’ or ‘loot’ weapon) effort, which encompassed everything from handguns to fighter aircraft with an official code in the Waffenamt system; for example FK-288(r) (the Soviet ZiS-3 anti-tank gun), SIGew-251(a) (the American M1 Garand rifle), and Sd.Kfz 735(i) (the Italian Fiat M13/40 tank). Captured gear was assembled at points called Sammelstelle and then shipped back from the front lines for disposition." etc.
