B-40: Quadrants

Previous: B-39: Direction of Fire

B-40. Quadrants are subdivisions of an area created by superimposing an imaginary pair of perpendicular axes over the terrain to create four separate areas or sectors. Establish quadrants on the terrain, friendly forces, or on the enemy formation.

Note. Techniques in which quadrants are based on enemy formations usually are referred to as target array; it is covered in discussion of threat-based fire control measures.

B-41. The method of quadrant numbering is established in the unit SOP; however, care must be taken to avoid confusion when quadrants based on terrain, friendly forces, and enemy formations are used simultaneously.
