29 JUL--This Day in US Military History

1970 – Volunteers of Pennsylvania’s 193rd Tactical Electronic Warfare Group settle into their quarters having just arrived to begin their secret mission of propaganda broadcasts over enemy held territory.

The 193rd was a fairly new organization, having been reorganized from Pennsylvania’s 168th Air Transport Group in 1967. During the 1965 operation of the U.S. military in quelling the unrest in the Dominican Republic, the Defense Department decided it need some way to communicate by AM radio with the populace our intentions and instructions to help reduce needless deaths. With the Vietnam War costing billions of dollars already, the Air Force said it could not organize such a specialized unit on a full-time basis. Major General Winston Wilson, the Chief of the National Guard Bureau, offered to have an Air Guard unit reorganized to perform this mission.
As the 168th was reorganized into the 193rd its mission was redefined more to broadcast the American position on events to enemy soldiers than to communicate with local civilians. Soon after the U.S. incursion into Cambodia from Vietnam in May 1970, it was decided to deploy the 193rd to Thailand to fly over Cambodia broadcasting to Communists forces attempting to overthrow the pro-American government.
By 1970 it was apparent that the U.S was withdrawing its forces from Vietnam. The last thing the Pentagon wanted was newspaper stories about a Guard unit again being mobilized for duty in Southeast Asia. The last of the Guardsmen mobilized in 1968 had only been released from active duty in November 1969. And with memories of the Guard’s involvement in the Kent State shootings that had just occurred in May 1970, the public’s impression of the Guard was not favorable. So it was decided to deploy the unit staffed entirely with volunteers on ‘short tours’ of 60-90 days before they returned home, replaced by new volunteers for another 60-90 days.
According to Technical Sergeant James Bankes, who was in the first group to go, this rotation schedule applied to all, pilots as well as ground support personnel. With little notice by the press the unit took only two of their specially-modified EC-121 Super Constellation aircraft. Each day one plane would fly, usually for about 7 hours, while the other was serviced and prepared for the next day’s mission. Bankes said that the planes broadcast AM radio programs in a foreign language prepared by somebody who delivered them to the unit each morning in time for that day’s flight. The crew had no idea what they said. One pilot joked it was probably “Shoot down the first three-tailed aircraft you see!”
After 144 days of continuous missions (without missing one day due to malfunction or weather) the unit and its planes returned home with no fanfare. The 193rd suffered no losses. This first test for the unit proved successful and it has been among the first unit deployed in every military action undertaken by the U.S. since Vietnam. In fact, the 193rd (now redesignated as Special Operations Wing) is the only such unit in the entire Air Force and was flying over Afghanistan broadcasting on the first day of the air war against the Taliban in 2001 and over Iraq in the opening hours of Operation Iraqi Freedom in 2003.
