Which of the following is NOT a Reconnaissance Method mentioned?

• A. Dismounted
• B. Mounted
• C. Aerial
• D. Surveillance

Answer: (D)

Reconnaissance methods are the primary ways a unit gathers information on the ground: dismounted on foot to close with the area, mounted on vehicles to cover ground quickly, and aerial to observe from above. Each method defines how you approach and observe the area. Surveillance isn’t listed as one of these primary methods in the material; it describes ongoing observation of a target rather than a distinct method of recon movement and collection. While surveillance can accompany recon, the standard methods are dismounted, mounted, and aerial, which is why surveillance is not considered a primary reconnaissance method in this context.
