Join us tonight as we talk with veterans of the Vietnam “Studies and Observation Group.” Don’t let the innocuous-sounding name fool you. SOG was what one recent article called “the most secret unit you’ve never heard of,” a classified joint Special Operations project that took the war in Vietnam across national borders and into enemy territory. Their uniforms bore no name tags, rank, or insignia. Their weapons had no serial numbers. The government denied their existence. Two SOG legends, John Meyer and Dick Thompson, join us tonight to discuss their secret war in Vietnam.
