Which item is typically depicted on a Sector Sketch for coordination?

• A. Rail Car Schedule
• B. Communications Net Diagram
• C. Defensive Positions, Sectors, and Lines of Fire
• D. Medical Evacuation Routes

Answer: (C)

Sector sketches for coordination are drawn to show how a battle area is divided among units, focusing on where each unit defends and what fires it can cover. The essential element depicted is defensive positions, the sectors assigned to each unit, and the lines of fire for those sectors. This setup lets commanders see at a glance who is responsible for which area, where fires are directed, and where gaps or overlaps might exist, enabling synchronized movement and fire discipline across the force. Other details like a rail car schedule belong to logistics, a communications net diagram belongs to signaling plans, and medical evacuation routes belong to medical plans; they’re not the primary focus of a sector sketch, which centers on positions, sector boundaries, and firing arcs.
