In WW2 things were procured as if there was a war going on. Lots of extra for sinkage, spoilage, pilferage. Even our initial purchases in the 50s had a substantial amount of spares, to the point that we were still getting 1950s marked parts as spares for the jeeps and dueces right into the 80s. But when it came to the 70s, the Trudeau are had kicked in, and the supply system was more of a push pull system, with annual usage forecasts etc. Parts were no longer procured to last for a 20 year cycle, but rather the supply system was run more like a business. As a result, we did not end up with the same quantities of surplus as in WW2 or even Korea for that matter.
