My late father (USMC WWII, Korea, Vietnam) helped burn millions of tons of brand-new lumber in the South Pacific when World War II was over. We left plenty of equipment in Vietnam, Iraq, the Philippines, etc.
My WWII Marine father saw the same when leaving the Marshall Islands at the end of the war. Jeeps, trucks,
airplanes & other equipment were dropped in the ocean just beyond the reef.
He was told the US manufacturers were promised nothing would come back at war’s end so the post war economy would not be depressed by military surplus in the marketplace.
