"The Professionals" chronicles the key events of the largest United States strategic communications base in the Vietnam War at Phu Lam, Vietnam, and relates the personal reminiscences of some of the men who served there. It documents the growth of the base, the circumstances under which five men were killed in action and its eventual "Vietnamization" and turnover to the South Vietnamese Army. This history is intended to recognize the accomplishments of the many U.S. Army communicators, known as "The Professionals," who served at Phu Lam and to help document the role of the U.S. Army Signal Corps in the Vietnam War.
