Military tactics are the techniques and procedures used to arrange and employ armed forces in combat. The term traces back to the Greek taktikē and covers how an army or smaller formations deploy weapons and military units against an enemy during a battle. Tactics operate on a shorter time horizon than strategy, focusing on immediate outcomes such as seizing terrain, forcing a withdrawal, or destroying an opposing unit.

Core principles and levels

Effective tactics rest on enduring principles: mass (concentrating combat power), maneuver (moving to advantageous positions), surprise, security, economy of force, and maintaining reserves. Tactics apply at multiple echelons — individual soldiers and small teams, squads and platoons, companies and battalions, and up through brigades and divisions — with decisions at each level affecting the rest.

Common tactical forms

Field practice includes a spectrum of methods. Some widely used forms are:

  • Frontal assaults — direct attacks intended to break the enemy’s line.
  • Flanking maneuvers — seeking to strike the enemy’s side or rear to disrupt formations.
  • Ambushes — concealed attacks against an unsuspecting force.
  • Shock tactics — rapid, violent actions designed to overwhelm morale and cohesion.
  • Use of reserves — holding units back to exploit success or plug gaps.
  • Combined-arms integration — coordinating infantry, armor, artillery, engineers and air assets to multiply effect.

Historical development

Tactics have evolved as weapons and technology changed. Phalanx and legion formations dominated ancient and classical eras; medieval tactics emphasized cavalry and fortification; the advent of gunpowder and rifled firearms reshaped engagements in the early modern period. Industrialization, mechanization and the introduction of aircraft and radios in the 20th century produced mobility, firepower and coordination that enabled new approaches such as blitzkrieg and modern combined-arms doctrine. Advances in military technology continue to alter tactical options, from precision-guided munitions to networked sensors.

Applications and contexts

Tactics are adapted to setting and scale. Urban warfare emphasizes clearing buildings and protecting civilians; counterinsurgency blends military action with political and informational tools; naval and air tactics focus on maneuver in three dimensions and control of lines of operation. Small-unit tactics prioritize communication, cover and bounding movements; large-scale maneuvers stress synchronization of fires and logistics.

Distinction from strategy and notable perspectives

While strategy links battles to political aims, tactics are the methods for winning those encounters. As the military theorist Carl von Clausewitz observed, "tactics is the art of using troops in battle; strategy is the art of using battles to win the war." Understanding tactics requires both study of historical examples and practical training, because human factors, terrain, weather and technology combine to make each engagement unique.
