Which of the following is NOT a recon method for RSOP?

• A. Map
• B. Air
• C. Ground
• D. Satellite

Answer: (D)

Reconnaissance for RSOP centers on getting current, on-site or direct information about terrain, hazards, and boundaries that could affect safety and operations. The practical methods used are map reconnaissance to study existing data and features, air reconnaissance to quickly observe large areas from above, and ground reconnaissance to verify actual on-site conditions like fences, access points, and any transient hazards. Satellite imagery, while helpful for broad planning, isn’t used as a recon method for RSOP because it doesn’t provide timely, verifiable, on-the-ground information needed for safety decisions. It can be outdated or limited by resolution and weather, and it can’t reliably reveal transient obstacles or verify current clearance and access—crucial factors for RSOP planning.
