Notice I used the word "initially" before "operated by". It is extremely difficult to follow the trail of these jeeps during their service life. For example when the Big switch to the M151 started in late 1959 the Army was directed to make the mass turnover quickly. Most of the M38A1's they turned in to the Defense Disposal Service were quickly procured by the USMC who then immediately sent those several thousand M38A1's to their own vehicl overhaul depots in Cal. and Georgia where they were repainted, had new Procurement Data plates installed and were undercoated and equipped with linited slip diff's.
Also it was common for these older jeeps to show up at family services and other base support services where they would languish unattended for many years. And we must also mention their disposal to the Reserve and Guard units.
