context_page_description: Coast Guard Squadron One, also known in official message traffic as COGARDRON ONE or RONONE, was a combat unit formed by the United States Coast Guard in 1965 for service during the Vietnam War. Placed under the operational control of the United States Navy, it was assigned duties in Operation Market Time. Its formation marked the first time since World War II that Coast Guard personnel were used extensively in a combat environment.
  The squadron operated divisions in three separate areas during the period of 1965 to 1970. Twenty-six Point-class cutters with their crews and a squadron support staff were assigned to the U.S. Navy with the mission of interdicting the movement of arms and supplies from the South China Sea into South Vietnam by Viet Cong and North Vietnam junk and trawler operators. The squadron also provided naval gunfire support to nearby friendly units operating along the South Vietnamese coastline and assisted the U.S. Navy during Operation Sealords. As the United States' direct involvement in combat operations wound down during 1969, squadron crews began training Republic of Vietnam Navy sailors in the operation and deployment of the cutters.

As the United States' direct involvement in combat operations wound down during 1969, squadron crews began training Republic of Vietnam Navy (RVN) sailors in the operation and deployment of the cutters. The cutters were later turned over to the RVN as part of the Vietnamization of the war effort. Turnover of the cutters to RVN crews began in May 1969 and was completed by August 1970. Squadron One was disestablished with the decommissioning of the last cutter.
  The squadron was awarded several unit citations for its service to the U.S. Navy and the South Vietnamese government during the six years the unit was active with over 3,000 Coast Guardsmen serving aboard cutters and on the squadron support staff. Six squadron members were killed in action during the time the unit was commissioned.
  Squadron One, along with American and South Vietnamese naval units assigned to the task force that assumed the Market Time mission, were successful interdicting seaborne North Vietnamese personnel and equipment from entering South Vietnamese waters. The success of the blockade served to change the dynamics of the Vietnam War, forcing the North Vietnamese to use a more costly and time-consuming route down the Ho Chi Minh trail to supply their forces in the south.
