3. Sea Echelon Concept o. The sea echelon concept is a plan to implement dispersal and reduce mine countermeasures. The decision for employment of a sea echelon is the responsibility of the amphibious task force com- mander. When the sea echelon is employed, it includes the follow- ing areas : (1) Transport area. The transport area is an area assigned to a transport organization for debarking troops and equipment. It consists of mineswept lanes, areas, and channels leading from a sea echelon area ( (2) below) to the beaches. The maximum number of ships in the transport area is directly limited by dispersion require- ments, availability of forces for mine countermeasures, and local hydrography and topography. Landing ship areas, helicopter transport areas, control ship stations, and fire support areas are dispersed within this swept area (FM 31-12). (2) Sea echelon area.
