3-64. A movement formation is an ordered arrangement of forces for a specific purpose and describes the general configuration of a unit on the ground. Commanders can use seven different movement formations depending on the mission variables: column, line, echelon (left or right), box, diamond, wedge, and vee. Terrain characteristics and visibility determine the actual arrangement and location of the unit’s personnel and vehicles within a given formation. (FM 3-90-1 describes these combat formations.)
