Tommy guns and Junks
Via U.S. Navy in the Vietnam War: In a scene that looks more like Burma in 1945 than Indochina in 1965, EN1 Carl L. Scott, an advisor to the Vietnamese Coastal Junk Force, stands in front of members of his team in this photo.
Note that EN1 Scott is wearing the authorized Junk Force beret and insignia along with common black “pajamas” worn by many of the Vietnamese, and carries a late WWII-era M1A1 Thompson submachine gun. Also, note the South Vietnamese with an M1 Garand and 10-pouch belt.
While the U.S. Army and Marines rarely used the Chicago Typewriter in Southeast Asia, typically only scoring occasional examples while working with ARVN units who had received them along with M1 Carbines and Garands as military aid, the Navy and Coast Guard utilized Tommy guns extensively in their brown water war, especially in the 1960s.
From NHHC on the Junk force:
Recognizing that the sea was a likely avenue of approach for Communists infiltrating from North Vietnam or moving along the South Vietnamese littoral, in April 1960 the navy established the paramilitary Coastal Force. In line with its emphasis on counterinsurgency warfare, the Kennedy administration wholeheartedly endorsed the development of this junk fleet, providing the force with American naval advisors, boat design and construction funds, and stocks of small arms. By the end of 1964, the 3,800-man, 600-junk force patrolled the offshore waters from 28 bases along the coast. To coordinate the operations of these 28 separate divisions, U.S. advisors helped set up coastal surveillance centers in Danang, Cam Ranh, Vung Tau, and An Thoi, the respective headquarters of the 1st, 2d, 3d, and 4th Coastal Districts.
Personnel problems proved equally vexing. Although authorized almost 4,000 men, the Coastal Force often fell short by 700 to 800 men. Lacking the prestige of the other combat branches and with its men underpaid and isolated in austere bases, the junk force had great difficulty recruiting personnel, especially those with technical knowledge. Further, only a few of the coastal group bases created formal training programs to increase the skills of those men enlisted. Encouraged by U.S. naval advisors, the Vietnamese Navy took limited steps in late 1967 and 1968 to improve the training effort and to better the living conditions of the junkmen, but much remained to be done.
