Military Science
Military tactics are the art and science of winning engagements and battles through the application of combat power. They translate strategy—the overall plan for achieving campaign or war aims—into concrete actions on the battlefield, involving the arrangement and maneuvering of forces, the selection of objectives, and the coordination of fire and movement. Tactics have evolved from ancient formations to modern network-centric warfare, yet core principles such as surprise, concentration, and economy of force remain timeless.
Military tactics are the techniques for winning battles, distinct from strategy, which concerns the overall campaign or war. In military doctrine, tactics occupy the lowest level of the three levels of war: grand strategy, operational art, and tactics. Tactics involve the specific employment of units—from squads to divisions—in engagements, focusing on the immediate application of combat power to achieve objectives. The operational level bridges strategy and tactics by planning campaigns and major operations, while tactics execute those plans in direct combat. For example, the U.S. Army's Field Manual 3-0 defines tactics as the “employment and ordered arrangement of forces in relation to each other.”
Tactics have evolved from ancient phalanxes and legions to modern combined-arms operations. The Greek phalanx relied on tightly packed spearmen, while Roman legions introduced maniples for greater flexibility. The advent of gunpowder shifted tactics toward linear formations and volley fire, as seen in the Napoleonic Wars. The 20th century brought blitzkrieg—a German tactic combining tanks, infantry, and air support for rapid penetration—and later, the U.S. developed AirLand Battle doctrine to counter Soviet massed armor in Europe. Today, network-centric warfare emphasizes information superiority and precision strikes, as demonstrated in the 1991 Gulf War.
Classical principles of war, such as surprise, concentration, economy of force, and offensive action, remain central to tactical thinking. Surprise can be achieved through deception, speed, or unexpected terrain. Concentration involves massing combat power at the decisive point, while economy of force allocates minimum resources to secondary efforts. Modern tactics also integrate the elements of combat power: maneuver, firepower, protection, and leadership. For instance, the U.S. Army's doctrine emphasizes combined arms—the synergistic use of infantry, armor, artillery, and aviation—to overwhelm an adversary. These principles are taught in military academies worldwide and are adapted to specific environments like urban, jungle, or desert warfare.
Contemporary conflicts have expanded tactics to include counterinsurgency, urban warfare, and cyber operations. Asymmetric tactics, used by non-state actors, often involve guerrilla warfare, improvised explosive devices (IEDs), and terrorism to counter superior conventional forces. In response, conventional militaries have developed counterinsurgency (COIN) tactics focusing on population security and winning hearts and minds, as outlined in the U.S. Army's Field Manual 3-24. Additionally, the rise of drones and cyber attacks has introduced new tactical domains, where electronic warfare and information operations can be as decisive as physical firepower. The 2020 Nagorno-Karabakh conflict highlighted the effectiveness of drone swarms against traditional armor.
Beyond the well-known doctrines, tactics include niche concepts like the “reconnaissance pull,” where units advance based on real-time intelligence rather than a fixed plan. The Soviet “deep battle” concept, developed in the 1920s, anticipated simultaneous attacks throughout the enemy's depth. In ancient China, Sun Tzu's “The Art of War” emphasized deception and the indirect approach, influencing modern maneuver warfare. Tactical innovations often arise from unexpected sources: the Swiss pikemen's squares defeated knights, and the British “penny packets” of tanks were a failed interwar experiment that shaped later armored doctrine. Even today, tactical manuals include obscure details like the proper employment of “defilade” to protect vehicles from direct fire.
Tactics are the building blocks of military success, evolving with technology and the nature of conflict.
