Special Forces — played a significant role in undercover and dangerous operations in Vietnam, often sending out small groups of soldiers into remote areas controlled by enemy forces. They also trained and assisted indigenous forces.
This jungle fatigue uniform was worn by Barker as a member of the Special Forces. Barker described this uniform as having been modified for conditions encountered in Vietnam, Cambodia and Laos. He said the jacket always was worn tucked in to reduce noise while he moved through the countryside. Pockets were moved up from the lower jacket or pants to the shoulders.
Special Forces teams wore no dog tags or anything else to identify them as Americans when they were on classified missions, such as the ones Barker took into Laos.
