You wish. Most of the stuff is just plain junk. I think that the government has a policy of once an item is declared obsolete or beyond economical repar or they just want to sell it, that it must stand out in the weather for at least 3 years bvefore it is sold.
And people who bid on it are insane! I watched people bid $175 for obsolete PDA's that were selling on ebay for $60!
Your beliefs may have credence, Blood of Tyrants:
The venerable M-113 Armored Personell Carrier was developed in the early 1950s. Put into Army Inventory in Europe in the Mid-1950s. Slated for the Scrap Heap and Obsolescence under Kennedy. Until Vietnam began to heat up. It's still alive and well in the Army's Inventory today.
