Which of the following best describes a Sector Sketch?

• A. A Map Showing Sector Boundaries and Firing Positions
• B. A List of Personnel
• C. A Timetable for Movement
• D. A Checklist for Ammo Only

Answer: (A)

A Sector Sketch is a map that shows sector boundaries and firing positions, giving leaders a clear visual reference of who is responsible for which area and where their fires are directed. It defines the assigned area of responsibility and the units’ sectors of fire, helping coordinate fires, prevent gaps or overlaps, and quickly orient during planning and execution. It typically includes boundaries, sectors of fire, key terrain, obstacles, and covered routes. The other items describe administrative or logistical documents—lists of personnel, movement timetables, or ammo checklists—that don’t illustrate how fires are coordinated within a sector.
