 Manoeuvre control measures are the basic preliminary step in effective clearance of fire support (e.g.artillery, Naval gunfire, and close air support), marked by imaginary boundary lines used by commanders to designate the geographical area for which a particular unit is tactically responsible.It is usually established on identifiable terrain to help aid in hasty referencing for better lateral advantage in the science of fire support, normally orchestrated by a higher echelon of the general staff, mainly the operations staff sections.
