Which of the following is a step in EA development?

• A. Direct-fire planning
• B. Describe environmental effects on operations
• C. Define the Operational Environment
• D. Evaluate the threat

Answer: (A)

Engagement Area development centers on shaping fires and movement to control an area, using planned, coordinated fires and obstacles to canalize the enemy. A crucial step is direct-fire planning, which translates the engagement area concept into concrete fire plans. This means deciding which direct-fire weapons will cover each sector, establishing exact lines of fire, ranges, and trigger conditions, and coordinating these with observation and fire. It creates interlocking, mutually supportive fires that defend the EA and deny enemy routes of approach.

The other items are important inputs to understanding the battlefield—defining the Operational Environment, describing environmental effects on operations, and evaluating the threat—but they feed the planning process rather than being the step that actually sets up the EA’s protective fires.
