Which tool helps in evaluating the adversary and identifying key terrain?

The tool that helps in evaluating the adversary and identifying key terrain is geographic overlays. This tool allows analysts to visualize geographic data in relation to various factors, such as the location of adversaries, resource availability, and terrain features. By layering data on maps, geographic overlays enable a comprehensive analysis of how physical terrain impacts strategic decisions and operational planning.

For instance, these overlays can highlight choke points, high ground, or areas that may provide tactical advantages or vulnerabilities, critical for understanding the adversary's movements and strategies. This visual representation aids in decision-making processes by allowing intelligence professionals to correlate geographic elements with enemy capabilities and intentions effectively.

In contrast, SWOT analysis focuses on assessing strengths, weaknesses, opportunities, and threats of an organization or situation rather than a geographical context. Force field analysis evaluates the forces for and against a change, making it less applicable in a military context focused on adversaries. Cost-benefit analysis, while useful in assessing the financial implications of decisions, does not directly support the evaluation of adversaries or terrain features.
