Which of the following relates to the tactical level of warfare?

The tactical level of warfare focuses on the direct execution of military actions, specifically in engagements and battles. This level involves the detailed planning and conduct of operations that aim to achieve specific objectives on the battlefield. By concentrating on battles and engagements, military leaders make decisions about troop movements, resource allocation, and immediate combat operations.

In contrast, strategic alliances, campaign planning, and global strategies all pertain to broader, more comprehensive aspects of military operations that guide the overall direction and objectives of warfare rather than the specific execution of those objectives in individual engagements. This distinction underscores why focusing on battles and engagements is the correct choice when discussing the tactical level of warfare.
