Naval Special Operation Force
During the First Indochina War, the river operations of the French army accounted for an important part of the battlefield. Taking advantage of Vietnam's territory with a long coastline, many rivers, and interlaced rivers like the Southwest region, the French army deployed a rather strong navy. The French Navy focuses on three main activities:

To counter the activities of the French Navy, the armed forces of the Viet Minh built French ship hunting squads, including naval special forces, in the riparian and coastal areas, ready to against the French on the river front. During the Battle of the Day River (June 1951), a task group led by Nguyễn Quang Vinh (of 36th Regiment, 308th Battalion) used bamboo boats with 300 kg of explosives to sink LCD ships carrying weapons of French army. This is the opening battle for how to fight warships on the Northern battlefield, creating a premise for the use of special forces to hit targets named rivers and seas. In the South, in early 1949, the Long Châu Sa ship hunting team used homemade mines to sink the Glycin ship on the Sài Thượng River, killing hundreds of enemy troops. In the Rừng Sác area, in September 1950, special teams were formed from the 300th Regiment, operating in the areas of Nhà Bè, Thủ Thiêm down to Cần Giờ, Soài Rạp. This force fought very bravely, daringly, known as "suicide troops", killing many French commanders and henchmen. Thus, in the early stages of the resistance war, along with the fighting style of the special forces, the fighting style of the Naval Special Force also began to develop. Based on the progress of weapons research and improvement, localities in the North and the South have organized a specialized force to hit ships and boats by special operations.
