A few years ago I was at Camp Shelby, MS.......this was before I was infected with the dreaded "Green Iron Affliction". My division had a brigade located on Shelby and on occasion I would drive a CUCV that belonged to the unit. This usually meant a trip to the Motor Pool to dispatch a vehicle which meant it had to be inspected by a mechanic. I got to know several of the guys there and would hang out with them if there was nothing going on (this was better than hanging around HQ and having some staff officer send you to the doughnut shop).
One week while I was there they were getting a bunch of deuces ready to turn in......they were writing them up as having bad engines or transfer cases which allowed them to be turned in non-running condition. This meant they did not have to have good tires, lights, tops, etc or their Basic Issue Items (BII)..this saved the unit money and time.
The guys were not above doing some creative wrenching to make the vehicle inoperable. The assumption was that they would go through DRMO as salvage trucks and be cut up.
One of the worst things I ever saw was almost brand 5 ton bridge trucks being sold as scrap and having to be cut up on the National Guard yard at Sheby.
This may explain why some trucks are listed as non-running.......according to the mechanics this was not uncommon among units that wanted to get rid of old stuff so they would not have to do Motor Stables and monthly maintenence on them.
