• A. Nuclear deterrence operations.
• B. Conventional battles between states.
• C. Cyber defense.
• D. Type of conflict involving acts such as guerrilla tactics, subversion, or sabotage.

Answer: (D)

Irregular warfare is a type of conflict where non-traditional, indirect methods are used to pursue political goals rather than relying on large-scale, formal battlefield battles. It centers on tactics like guerrilla operations—small, mobile units conducting hit-and-run or ambush attacks; subversion—undermining an opponent’s legitimacy, governance, and social order; and sabotage—disrupting critical infrastructure to degrade the opponent’s capabilities and will to fight. These approaches are often employed by insurgents or other non-state or irregular actors and typically blend military, political, economic, informational, and cyber tools to achieve objectives without open, conventional clashes. This makes it distinct from conventional warfare, which focuses on direct engagements between regular armed forces on defined fronts. Nuclear deterrence operations rely on threatening massive retaliation to deter conflict, not on irregular, covert, or insurgent methods. Cyber defense, while crucial, is a defensive domain and does not define the nature of irregular warfare.
