Which of the following lists potential threats?

• A. Conventional military, special forces, foreign intelligence agents, terrorists, criminal elements, extremist groups, insider threats
• B. Cyber threats and lone actors only
• C. Local visitors and vendors
• D. Natural disasters

Answer: (A)

Threat assessment in a military security context must account for a wide range of actors who could pose harm, not just a single category. A comprehensive view includes external actors with formal power and clandestine capabilities, as well as internal risks from people who have access. This means recognizing conventional military forces and specialized units as potential external threats, foreign intelligence operators who could gather or exploit information, terrorists and extremist organizations that use violence to advance aims, organized criminals who disrupt or steal, and insider threats where damage comes from within. That combination covers state and non-state actors, as well as those who could misuse authorized access, giving the most complete picture of potential hazards.

Choosing a narrower set—like only cyber threats and lone actors—misses many realistic risk sources. Focusing only on local visitors and vendors or on natural disasters leaves out major human-driven threats that security planning must consider.
