What details several positions, sector of fire, and areas in & around them?

• A. Range Card
• B. Fire Plan
• C. Area Map
• D. Sector Sketch

Answer: (D)

The main idea here is showing how several weapon positions cover an area through their fields of fire. A Sector Sketch is the graphic tool that lays out multiple positions and the exact sectors of fire each one is responsible for, along with the surrounding terrain and areas that must be monitored or covered. It lets you see at a glance how the units interlock their fires, where gaps could exist, and how reinforcement or maneuver might occur given the layout of the battlefield.

This makes it the best fit for a question asking for details of several positions, their sector of fire, and the areas around them. It translates planning into a visual arrangement, clarifying which positions cover which angles, how they overlap, and what routes or terrain features influence coverage.

To contrast briefly: a range card focuses on a single weapon position, noting ranges to targets and possible engagement lines from that position; it doesn’t map multiple positions and their combined sectors. A fire plan coordinates who fires where during a mission but doesn’t provide the map-like depiction of interlocking sectors for several positions. An area map shows terrain and locations but not the specific, interlocking sectors of fire for multiple positions.
