What is the primary purpose of barriers and obstacles?

• A. To completely prevent any entry without exception.
• B. To improve the aesthetic value of the perimeter.
• C. Channel, direct, restrict, delay, or stop opposing force; impose losses.
• D. To replace the need for patrols.

Answer: (C)

Barriers and obstacles are used to influence how an opposing force moves and to increase the cost of an attack. Their purpose is to channel, direct, restrict, delay, or stop the adversary, while inflicting losses through exposure and wasted time. This shaping of the attack makes it harder for the attacker to reach the objective and gives defenders more time to detect and respond. No barrier can guarantee perfect entry prevention, so they are tools in a layered defense rather than absolute safeguards. Aesthetic value is not the aim, and barriers do not replace patrols—they complement patrols and surveillance as part of a broader security plan.
