During WW2, how much did the opposing sides make use of material they captured?
For example, the British lost a lot of equipment at Dunkirk and the fall of Singapore; the Axis powers left huge amounts of material behind when they were driven out of North Africa. Is there evidence of the victors in those battles directly using captured vehicles, weapons ammunition etc? (Food would obviously be used, but there would be calibre problems with small arms and artillery ammunition, right?) Or were these things stripped down for parts in the field / sent to factories to be dissassembled and recycled?
