Military tactics encompasses the art of organizing and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are closely related – kinetic or firepower, mobility, protection or security, and shock action. Tactics are a separate function from command and control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels. Throughout history, there has been a shifting balance between the four tactical functions, generally based on the application of military technology, which has led to one or more of the tactical functions being dominant for a period of time, usually accompanied by the dominance of an associated fighting arm deployed on the battlefield, such as infantry, artillery, cavalry or tanks.
Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other.
A brigade is a major tactical military formation that typically comprises three to six battalions plus supporting elements. It is roughly equivalent to an enlarged or reinforced regiment. Two or more brigades may constitute a division.
A frontal assault is a military tactic which involves a direct, full-force attack on the front line of an enemy force, rather than to the flanks or rear of the enemy. It allows for a quick and decisive victory, but at the cost of subjecting the attackers to the maximum defensive power of the enemy; this can make frontal assaults costly even if successful, and often disastrously costly if unsuccessful. It may be used as a last resort when time, terrain, limited command control, or low troop quality do not allow for any battlefield flexibility. The risks of a frontal assault can be mitigated by the use of heavy supporting fire, diversionary attacks, the use of cover, or infiltration tactics.
The 1st Cavalry Division is a combined arms division and is one of the most decorated combat divisions of the United States Army. It is based at Fort Cavazos, Texas. It was formed in 1921 and served during World War II, the Korean War, the Vietnam War, the Persian Gulf War, with the Stabilization Force in Bosnia-Herzegovina, in the Iraq War, in the War in Afghanistan as well as Operation Freedom's Sentinel and Operation Inherent Resolve. As of July 2023, the 1st Cavalry Division is subordinate to III Armored Corps and is commanded by Major General Kevin D. Admiral.
Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They are usually deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing.
In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.
Maneuver warfare, or manoeuvre warfare, is a military strategy which emphasizes movement, initiative and surprise to achieve a position of advantage. Maneuver seeks to inflict losses indirectly by envelopment, encirclement and disruption, while minimizing the need to engage in frontal combat. In contrast to attrition warfare where strength tends to be applied against strength, maneuver warfare attempts to apply strength against weakness in order to accomplish the mission.
The People's Liberation Army Ground Force is the land-based service branch of the People's Liberation Army and the largest and oldest branch of the entire Chinese armed forces. The PLAGF can trace its lineage from 1927 as the Chinese Red Army; however, it was not officially established until 1948.
The following outline is provided as an overview of and topical guide to military science:
The first evidence of horses in warfare dates from Eurasia between 4000 and 3000 BC. A Sumerian illustration of warfare from 2500 BC depicts some type of equine pulling wagons. By 1600 BC, improved harness and chariot designs made chariot warfare common throughout the Ancient Near East, and the earliest written training manual for war horses was a guide for training chariot horses written about 1350 BC. As formal cavalry tactics replaced the chariot, so did new training methods, and by 360 BC, the Greek cavalry officer Xenophon had written an extensive treatise on horsemanship. The effectiveness of horses in battle was also revolutionized by improvements in technology, such as the invention of the saddle, the stirrup, and the horse collar.
In the United States Army, the term combat support refers to units that provide fire support and operational assistance to combat elements. Combat support units provide specialized support functions to combat units in the following areas
The Royal Prussian Army served as the army of the Kingdom of Prussia. It became vital to the development of Prussia as a European power.

Combat arms are troops within national armed forces who participate in direct tactical ground combat. In general, they are units that carry or employ weapons, such as infantry, cavalry, and artillery units. The use of multiple combat arms in mutually supporting ways is known as combined arms. In some armies, notably the British Army and Canadian Army, artillery and combat engineer units are categorized as combat support, while in others, such as the U.S. Army, they are considered part of the combat arms. Armored troops constitute a combat arm in name, although many have histories derived from cavalry units.
Military art is a field of theoretical research and training methodology in military science used in the conduct of military operations on land, in the maritime or air environments. Military art includes the study and application of the principles of warfare and laws of war that apply equally to the closely interrelated military strategy, operational art and tactics. Exercise of military art is highly dependent on the economics and logistics supporting the armed forces, their military technology and equipment, and reflects the social influences on the military organisation exercising military art. Often misunderstood due to its 19th-century perception as generally "including the entire subject of war", it is primarily, as the term implies, the expression of creative thinking on the part of the decision-makers in employing their forces, with the map of the area of operations as a veritable canvas, and the movement of forces commonly marked on the map with arrows, as brush strokes. Less imaginatively it was defined in France during the 19th century as
The art of war is the art of concentrating and employing, at the opportune moment, a superior force of troops upon the decisive point.
The Tactica is a military treatise written by or on behalf of Byzantine Emperor Leo VI the Wise in c. 895–908, and later edited by his son, Constantine VII. Drawing on earlier authors such as Aelian, Onasander and the Strategikon of emperor Maurice, it is one of the major works on Byzantine military tactics, written on the eve of Byzantium's "age of reconquest". The original Greek title is τῶν ἐν πολέμοις τακτικῶν σύντομος παράδοσις. The Tactica elaborates on a wide variety of issues, such as infantry and cavalry formations, drills, siege and naval warfare etc. It is written in a legislative form of language and comprises 20 Constitutions and an Epilogue and is concluded by 12 additional chapters, the latter mainly focusing on ancient tactics.
The hammer and anvil is a military tactic involving the use of two primary forces, one to pin down an enemy, and the other to smash or defeat the opponent with an encirclement maneuver. It may involve a frontal assault by one part of the force, playing a slower-moving or more static role. The second phase involves a more mobile force that maneuvers around the enemy and attacks from behind or the flank to deliver a decisive blow. The "hammer and anvil" tactic is fundamentally a single envelopment, and is to be distinguished from a simple encirclement where one group simply keeps an enemy occupied, while a flanking force delivers the coup de grace. The strongest expression of the concept is where both echelons are sufficient in themselves to strike a decisive blow. The "anvil" echelon here is not a mere diversionary gambit, but a substantial body that hits the enemy hard to pin him down and grind away his strength. The "hammer" or maneuver element succeeds because the anvil force materially or substantially weakens the enemy, preventing him from adjusting to the threat in his flank or rear. Other variants of the concept allow for an enemy to be held fast by a substantial blocking or holding force, while a strong echelon, or hammer, delivers the decisive blow. In all scenarios, both the hammer and anvil elements are substantial entities that can cause significant material damage to opponents, as opposed to light diversionary, or small scale holding units.
The structure of the United States Army is complex, and can be interpreted in several different ways: active/reserve, operational/administrative, and branches/functional areas.
A company is a military unit of the United States Army which has been in use since the American Revolutionary War. It has historically been commanded by a captain, assisted by a first sergeant as the senior-most non-commissioned officer (NCO), and consisted of approximately one hundred soldiers. Soldiers were divided between three and five platoons of around thirty each and led by a lieutenant. However the exact size and composition of a company has varied depending on the time period and its role.
