What type of warfare employs tactics such as guerrilla tactics and subversion?

The correct response is identified as being associated with irregular warfare. This form of warfare predominantly utilizes unconventional tactics, which effectively include guerrilla tactics and efforts aimed at subverting an adversary. Irregular warfare is characterized by its focus on non-state actors or revolutionary movements, employing smaller, adaptable units that can blend into the local populace. The techniques utilized in this type of warfare often aim to disrupt the enemy’s operations through ambushes, sabotage, and efforts to undermine legitimacy or authority.

In contrast, conventional warfare typically involves large, traditional military forces engaging in open conflict with clear front lines and uniformed combatants. Hybrid warfare combines both conventional and irregular methods to create a more complex battlefield scenario. Psychological warfare aims to influence the perceptions and emotions of the adversary or civilian population, rather than utilizing direct physical confrontations or guerrilla tactics. Thus, irregular warfare specifically encapsulates the use of guerrilla tactics and subversion, making it the most fitting choice.
