Things like oil products and metals were rationed during the wars to free them up for military use. What other strategies were used to increase the supply of these materials? Were existing vehicles stripped and recycled for their metal or re-purposed for military use? Were mining and refining facilities targets for capture by advancing forces? Were previously protected forests allowed to be cut down? I'm interested in the topic in general so book or article recommendations would be very welcome! :)

Apologies if this has been asked previously, my searches gave little other than food rationing questions.
