NO way to know for sure! Sadly. Most were certainly never sent overseas. They were used at various Forts/Camps for training purposes. Some stationed at various Forts or Airfields for other uses. Certainly: some were brought back to the states from Europe/UK as we prepared to invade Japan, how many??? Even post war units would train here and when deployed (called gyroscoping) they would send only the troops. Trading vehicles with the unit they were relieving.
