Which of the following is NOT a method to accomplish depth in defense?

• A. Patrolling
• B. Use of blocking positions
• C. Employ weapons at close range
• D. Planning decisive action for least engaged units

Answer: (C)

Using weapons at close range is not a method to accomplish depth in defense, as depth in a defensive posture refers to the strategic placement of forces and resources across a horizontal spectrum to create multiple layers of defense. This depth allows for flexibility, the ability to absorb and respond to enemy attacks, and provides time for forces to react and counterattack effectively.

In contrast, patrolling is a method used to increase the defense by maintaining situational awareness and disrupting enemy operations. Blocking positions serve as designated areas that can effectively halt or slow down an assault, acting as an additional layer of defense. Planning decisive action for the least engaged units ensures that those forces can reinforce critical areas or exploit opportunities as they arise, thus contributing to overall depth in defense. Each of these methods adds layers or depth to a defensive strategy, whereas employing weapons at close range is typically a more immediate and reactive tactic rather than a comprehensive approach to depth.
