I served in the US Army from 1959 to 1982. During my early assignments, my associated unit, the 72nd Signal Battalion, Combat Electronic Warfare (Corps)provided the soldier support to the Electronic Proving Ground along with a separate Electronic Warfare Support Company.

I was station at Fort Huachuca from 1960 – 1962 and from 1963 – 1964 when the 72nd was deactivated (September 1964) as the Signal Corps turned over the Electronic Warfare mission to the US Army Security Agency (ASA). I was an operator and later a Team Chief of a Multipurpose Jamming Section; a Variable Time Fuze Section (the Jeep with the folding antenna is a VT Fuze Jammer) and an Airborne Jamming Platform mounted in a U-1A De Havilland Otter aircraft.

It looks like a proto-DARPA.
