The humble beginnings of the U.S. Army Operational Test Command began in a storeroom of the old III Corps conference room on October 1, 1969.  A small group of military and civilian employees launched a unique test organization that has now spanned over 40 years, evolving from MASSTER into the dynamic organization that it is today.


"The American soldier will use his ingenuity to make the equipment work.  This does not absolve us if we send him into battle with a piece of junk."
