Tactical formation in the context of "Pike and shot"

The phalanx (pl.: phalanxes or phalanges) was a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar polearms tightly packed together. The term is used today to describe the use of this formation in ancient Greek warfare, but ancient Greek writers used it more broadly to describe any massed infantry formation regardless of its equipment. In Greek texts, the phalanx may be deployed for battle, on the march, or even camped, thus describing the mass of infantry or cavalry that would deploy in line during battle. They marched forward as one entity.

The term itself, as used today, does not refer to a distinctive military unit or division (e.g., the Roman legion or the contemporary Western-type battalion), but to the type of formation of an army's troops. Therefore, this term does not indicate a standard combat strength or composition but includes the total number of infantry, which is deployed in a single formation known as a "phalanx".

In military terminology, a column is a tactical formation of fighters moving together in one or more files in which the file is significantly longer than the width of ranks in the formation. The column formation allows the unit rapid movement and a very effective charge (due to weight of numbers), and it can quickly form square to resist cavalry attacks, but by its nature only a fraction of its muskets are able to open fire.

The line formation offers a substantially larger musket frontage than the column, allowing for greater shooting capability, but requires extensive training to allow the unit to move over ground as one while retaining the line. It is also applied by modern armies to vehicles, troops and naval vessels.

The pike square (German: Gevierthaufen, lit. 'square crowd', or Gewalthaufen lit. 'crowd of force') was a military tactical formation in which 10 rows of men in 10 columns wielded pikes. It was developed by the Swiss Confederacy during the 14th century for use by its infantry.

A bayonet (from Old French bayonette, now spelt baïonnette) is a knife, dagger, sword, or spike-shaped melee weapon designed to be mounted on the end of the barrel of a rifle, carbine, musket or similar long firearm, allowing the gun to be used as an improvised spear in close combat.

The term is derived from the town of Bayonne in southwestern France, where bayonets were supposedly first used by Basques in the 17th century. From the early 17th to the early 20th century, it was an infantry melee weapon used for both offensive and defensive tactics, usually when charging in mass formations (human wave attacks). In contemporary times, bayonets are considered a weapon of last resort, and are rarely used in combat, although they are still used for ceremonial purposes (e.g, military parades).

The combat box was a tactical formation used by heavy (strategic) bombers of the U.S. Army Air Forces during World War II. The combat box was also referred to as a "staggered formation". Its defensive purpose was in massing the firepower of the bombers' guns, while offensively it concentrated the release of bombs on a target.

Initially formations were created in keeping with the pre-war Air Corps doctrine that massed bombers could attack and destroy targets in daylight without fighter escort, relying on interlocking fire from their defensive machine guns, almost exclusively the "light barrel" Browning AN/M2 .50 calibre (12.7 mm) gun. However the use of high altitudes by USAAF bombers resulted in factors that demanded a tighter bomb pattern and the combat box continued in use even after the advent of fighter escort largely mitigated the threat of fighter interception. It was especially used over Europe during and after the spring of 1944, with USAAF fighters flying far ahead of the combat boxes in air supremacy mode instead against the Luftwaffe's fighters.

The line formation is a standard tactical formation which was used in early modern warfare.It continued the phalanx formation or shield wall of infantry armed with polearms in use during antiquity and the Middle Ages.

The line formation provided the best frontage for volley fire, while sacrificing maneuverability and defence against cavalry. It came to the fore during the Age of Reason, when it was used to great effect by Frederick the Great and his enemies during the Seven Years' War. The line formation was very successfully first used with combined arms in the Thirty Years War by the Swedish king Gustavus Adolphus the Great, at the Battle of Breitenfeld.

A close order formation is a military tactical formation in which soldiers are close together and regularly arranged for the tactical concentration of force. It was used by heavy infantry in ancient warfare, as the basis for shield wall and phalanx tactics, to multiply their effective weight of arms by their weight of numbers. In the Late Middle Ages, Swiss pikemen and German Landsknechts used close order formations that were similar to ancient phalanxes.

Around the American Civil War (1861–1865), such organizations of soldiers became uncommon since improvements in firearms and artillery had made any such dense formation increasingly hazardous and less effective. The technological concentration of increased firepower to fewer soldiers had rendered the close order formation obsolete by the end of the 19th century. Modern infantry now use skirmish order, which is effectively the opposite of close order.

A shield wall (scieldweall or bordweall in Old English, skjaldborg in Old Norse) is a military formation that was common in ancient and medieval warfare. There were many slight variations of this formation,but the common factor was soldiers standing shoulder to shoulder and holding their shields so that they would abut or overlap. Each soldier thus benefited from the protection of the shields of his neighbors and his own.
