What distance in feet should the boundary barrier for restricted areas be located from the base perimeter?

• A. 100 feet
• B. 250 feet
• C. 500 feet
• D. 1000 feet

Answer: (B)

Setting a boundary barrier a specific distance from the base perimeter creates a security buffer where detection, access control, and response assets can operate before any intruder reaches the restricted areas. The best distance balances deterrence, detection capability, and practical operations. At 250 feet, there’s enough space for guards, cameras, sensors, and barriers to interdict or slow down someone attempting to bypass the outer perimeter, while still keeping the restricted area reachable for authorized traffic and security response. A shorter distance, like 100 feet, leaves less reaction time and fewer maneuvering room for surveillance and interception. Much longer distances, such as 500 or 1000 feet, would add unnecessary cost, complicate infrastructure layout, and potentially hinder rapid response. So, 250 feet provides an effective middle ground that enhances protection without imposing excessive burden on operations.
