How many forms of physical surveillance are recognized?

The correct answer identifies that there are two forms of physical surveillance recognized. This includes both overt and covert surveillance.

Overt surveillance is conducted in a way that is visible to those being observed, allowing the subjects to be aware that they are under surveillance. This can involve the use of uniformed personnel or marked vehicles. The primary goal of overt surveillance is often deterrence, as the awareness of being watched can influence behavior.

Covert surveillance, on the other hand, is conducted without the knowledge of the subject. This form aims to collect intelligence discreetly and is crucial in situations where the subject's awareness could compromise the information being gathered. Personnel involved in covert operations typically use unmarked vehicles and maintain a low profile to avoid detection.

Understanding these two forms of surveillance is essential for effective law enforcement and security operations, particularly in roles such as those held by Master-at-Arms, who must be adept at both types to ensure efficient and secure monitoring of environments where they work.
