Which of the following best describes irregular warfare?

Irregular warfare is characterized by non-traditional combat methods primarily focusing on asymmetric tactics. This form of warfare typically involves smaller, adaptable, and decentralized groups engaging in guerrilla tactics to counter larger, conventional military forces. Such tactics may include ambushes, sabotage, and hit-and-run attacks, aiming to exploit weaknesses in a more powerful enemy rather than engaging in direct conventional confrontations.

This definition distinguishes irregular warfare from traditional forms, which might involve heavy conventional forces, like those implied in the other choices. The involvement of heavy conventional forces would not accurately describe irregular warfare, as it is defined specifically by its non-traditional approach. While cybersecurity measures are increasingly important in modern conflicts, they do not encompass the broader scope of irregular warfare, which is fundamentally about ground-level, unconventional combat. Lastly, the use of air superiority and naval blockades represents traditional methods of warfare, which focus on controlling the air and sea environments rather than the irregular tactics that define this type of engagement.
