Tactics

The art of combining, in operations, the action of all military assets to reach the objectives assigned by the operational strategy.
A component of military art, embracing both the theory and the practice of preparing and conducting operations involving subunits, units (ships), and tactical formations of the various armed forces, arms of the service, arm or branch, and specialized support troops. Theoretical tactics examine the principles, nature, and essential features of combat, developing procedures for its preparation and conduct. Applied tactics cover the practice of tactical-level commanders, staff, and troops in preparing for and engaging in combat. This includes the constant review of the situation; the commander's plan; the assignment of tasks to subordinate forces; the organization of cooperation; operational planning and tactical mission preparation; conduct of operations and
command and control of units and subunits; comprehensive support of combat operations [Балабін, Гардера, p. 263].
This means military forces' techniques for combining and using weapons and military units to engage and defeat an enemy in battle [IGI Global].
