X-WR-CALDESC:On 13 May 1961\, the first contingent of Army Security Agency 
 personnel arrived in South Vietnam (setting up an organization at Tan Son 
 Nhut Air Base) to provide support to the U.S. Military Assistance Advisory
  Group and help train the South Vietnamese Army. During the early years of
  conflict\, ASA troops in Vietnam were assigned to the 3rd Radio Research 
 Unit. Their primary mission was to locate Viet Cong transmitters operating
  in the south. \n\nThis mission was in its early stages when one of their 
 direction finding (DF) operators\, <b>SP4 James T. Davis\,</b> was killed 
 in a Viet Cong ambush on a road outside Saigon. The date of the ambush\, 2
 2 December 1961\, made Davis the <b>first American cryptologist to lose hi
 s life during the Vietnam War.</b> Click the link below to learn about SP4
  Davis in a special NSA pdf. \n\nSP4 Davis' name is engraved on the NSA/CS
 S Cryptologic Memorial Wall. The wall\, dedicated in 1996\, lists the name
 s of 176 Army\, Navy\, Air Force\, Marine\, and civilian cryptologists who
  have made the ultimate sacrifice\, 'serving in silence\,' in the performa
 nce of their duties since World War II. Learn more via the links below.
