Which of the following is NOT a level of warfare?

The correct answer is that 'Technical' is not recognized as an official level of warfare within military doctrine. The three established levels of warfare are Strategic, Operational, and Tactical.

Strategic warfare pertains to the overarching goals and decisions made to achieve national or coalition objectives, often involving a broad scope that encompasses global or regional issues. Operational warfare focuses on the planning and execution of campaigns and major operations to achieve strategic objectives, while Tactical warfare deals with the conduct of battles and engagements at a more immediate and localized level.

Each of these levels has specific implications in military planning and execution, and understanding them is crucial for successful military operations. 'Technical' does not align with this hierarchy, as it pertains more to specific technologies or systems rather than a level of warfare in itself. Therefore, it is distinct from the recognized levels that guide military strategy and operations.
