Which of the following is a valid route control measure?

• A. Open route
• B. Closed route
• C. Hidden route
• D. Random route

Answer: (A)

Route control measures describe how you manage movement through an area to balance speed with security. An open route is a recognized approach that keeps a route available for passage with standard security measures in place, allowing efficient movement when the threat level is manageable. It’s used to maintain flow and reduce delays, rather than imposing heavy restrictions.

The other terms aren’t standard route-control categories in typical doctrine; a closed route exists as a stricter option in higher-threat situations, while hidden or random routes aren’t established, formal classifications for controlling movement. So, open route best fits the concept of a valid, commonly used route control measure for normal conditions.
