the waters of the Mekong and Red rivers, conducting search and destroy missions, against communist guerillas and river pirates. They succeeded the river flotillas created in 1945, by the request of General Leclerc. The Dinassaut served until the end of the conflict in 1955, and its concept would be latter adopted by the United States Navy in the Vietnam War. Ten Dinassauts were created, with five based in Cochinchina and the others in Tonkin. Each one was made of about ten vessels and one Commandos Marine unit. The types of vessels operated by a Dinassaut included LCI, LCT, LCM, LCVP, LCS, LCA, LSSL and fire support vessels. The role of the Dinassaut was to transport, land and support the infantry, to patrol the watercourses and to assure the supply of the isolated posts. The sailors that served in the Dinassaut were referred as the "Navy in Khaki", in comparison with the sailors that served in the ocean that were referred as the "Navy in White". Portuguese Colonial War In Portuguese service, the brown-water navy has been often referred as the "Naval Dust" (), for its use of a large number of small vessels, in comparison with the conventional blue-water navy that uses a smaller number of larger vessels. In several historical periods, the Portuguese Navy had to develop riverine forces to operate in then-Portuguese colonies in Asia, South America and Africa. During the Portuguese Colonial War, from 1961 to 1974, the Portuguese Navy created a brown-water navy to operate in the rivers and lakes of Angola, Portuguese Guinea and Mozambique, against the separatist, communist guerrillas, as well as river pirates. For the organization of their riverine forces, the Portuguese were inspired by the French experience in Indochina with the Dinassaut and by their own historical experience in the operation of river flotillas in support of the Portuguese colonial pacification campaigns in Africa during the late 19th and early 20th centuries. Under the local commands of the Navy, the Portuguese created river boat flotillas (esquadrilhas de lanchas) in the Zaire River in Angola, in the Lake Nyasa in Mozambique and in the river system of the Portuguese Guinea. Smaller riverine forces were also created in the Cabinda Province of Angola, in Eastern Angola (to operate in the Cuito, Zambezi, Cuando, Lungué Bungo and Cuanza rivers) and in Tete to operate in the Mozambican section of the Zambezi river. These forces were
