Which of the following is NOT a type of guard?

• A. Advance guard (Stationary and moving)
• B. Flank guard (Stationary and moving)
• C. Rear guard (Stationary and moving)
• D. Screening guard (a general security function but not a guard type)

Answer: (D)

The idea being tested is how security for a moving force is organized into specific protective roles. Guards are employed to defend a route or position by occupying lines and engaging threats as the force moves or rests. The advance guard goes ahead to clear and secure the path, the flank guard protects the sides, and the rear guard watches the back and slows any pursuing force. Screening, on the other hand, is a reconnaissance function: a force is sent out to observe, report on enemy activity, and warn the main body of threats before they reach it. It doesn’t hold a position along the march or defend a flank or rear; its purpose is information and early warning rather than direct protection along the route. So screening is not a type of guard.
