This Vietnam war USN machine-embroidered patch measures 3.7\" by 2.7\" - used condition. A great find for any military collectible enthusiast.
The Navy entered the Vietnam War in 1960, when the UDTs delivered a small watercraft far up the Mekong River into Laos. In 1961, Naval advisers started training the South Vietnamese UDT. These men were called the Liên Đoàn Người Nhái (LDNN), roughly translated as the \"soldiers that fight under the sea\". The UDT also carried out hydro-graphic surveys in South Vietnam\'s coastal waters. Later, the UDTs supported the Amphibious Ready Groups operating on South Vietnam\'s rivers. UDTs manned riverine patrol craft and went ashore to demolish obstacles and enemy bunkers. These Detachments operated throughout South Vietnam, from the Mekong Delta (Sea Float), The Parrot Beak and French canal AO\'s through I Corp and the Song Cui Dai Estuary south of Da Nang. In the mid-1950s, the Navy saw how the UDT\'s mission had expanded to a broad range of \"unconventional warfare\", but also that this clashed with the UDT\'s traditional focus on swimming and diving operations. It was therefore decided to create a new type of unit that would build on the UDT\'s elite qualities and water-borne expertise, but would add land combat skills, including parachute training and guerrilla/counterinsurgency operations. These new teams would eventually replace the UDTs. The new force was the United States Navy SEALs (SEAL for their ability to operate by \"Sea-Air-Land\".) However, implementation of this program lagged. Then President John F. Kennedy took office. Kennedy recognized the need for unconventional warfare, and supported the use of special operations forces against guerrilla activity. The Navy moved to establish its role in special operations. In January 1962, SEAL Team One was commissioned. The SEALs expanded their numbers and roles through the 1960s and 1970s.
