Which option best describes a Level I threat?

• A. Enemy agents and terrorists whose primary missions include espionage, sabotage, and subversion.
• B. Insider threats
• C. Small-scale irregular forces conducting unconventional warfare (guerrillas, standoff weapons).
• D. Enemy capable of projecting combat power by air, land, or sea anywhere into operational area.

Answer: (A)

Level I threats come from outside the organization and focus on covert actions to obtain information or disrupt operations. The description that best fits this is enemy agents and terrorists whose primary missions include espionage, sabotage, and subversion, because these activities are classic external, clandestine aims aimed at weakening or compromising a target from outside. Insider threats originate from people inside the organization, which is a different category with internal access concerns. Small-scale irregular forces conducting guerrilla-style warfare describe insurgent activity focused on unconventional tactics within a conflict, not primarily on espionage or subversion against a target. An enemy able to project power by air, land, or sea into the operational area represents a more capable conventional threat, typically associated with higher threat levels than Level I.
