Which level of military authority is responsible for tactical decisions on the battlefield?

Tactical-level commanders are responsible for making decisions that directly impact battlefield operations and engagements. Their focus is on the immediate execution of plans and actions during combat, including troop movements, equipment deployment, and real-time adjustments to strategies based on situational developments. These commanders operate at the lowest level of military authority, where direct interaction with frontline forces occurs.

In contrast, strategic-level commanders plan and direct overall military objectives, guiding long-term goals and resource allocation rather than handling immediate battlefield decisions. Operational-level commanders function between strategic and tactical levels, focusing on how to best allocate resources and organize forces in support of strategic objectives, without engaging in the on-ground decision-making that defines tactical command. Administrative-level commanders oversee the logistical and support elements necessary for operations but do not engage in combat decision-making on the battlefield.
