Spears in the context of "Lozenge (shape)"

Warfare occurred throughout the history of Ancient Greece, from the Greek Dark Ages onward. The Greek Dark Ages drew to an end as a significant increase in population allowed urbanized culture to be restored, which led to the rise of the city-states (poleis). These developments ushered in the period of Archaic Greece (800–480 BC). They also restored the capability of organized warfare between these poleis (as opposed to small-scale raids to acquire livestock and grain, for example). The fractious nature of Ancient Greek society seems to have made continuous conflict on this larger scale inevitable.

Along with the rise of the city-state evolved a new style of warfare: the hoplite phalanx. Hoplites were armored infantrymen, armed with spears and shields. Seen in media, the phalanx was a formation of these soldiers with their shields locked together and spears pointed forward. The Chigi vase, dated to around 650 BC, is the earliest depiction of a hoplite in full battle array. With this evolution in warfare, battles seem to have consisted mostly of the clash of hoplite phalanxes from the city-states in conflict. Since the soldiers were citizens with other occupations, warfare was limited in distance, season and scale. Neither side could afford heavy casualties or sustained campaigns, so conflicts seem to have been resolved by a single set-piece battle.

Hand-to-hand combat is a physical confrontation between two or more persons at short range (grappling distance or within the physical reach of a handheld weapon) that does not involve the use of ranged weapons. The phrase "hand-to-hand" sometimes includes use of melee weapons such as knives, swords, clubs, spears, axes, or improvised weapons such as entrenching tools. While the term "hand-to-hand combat" originally referred principally to engagements by combatants on the battlefield, it can also refer to any personal physical engagement by two or more people, including law enforcement officers, civilians, and criminals.

Combat within close quarters, to a range just beyond grappling distance, is commonly termed close combat or close-quarters combat. It may include lethal and non-lethal weapons and methods depending upon the restrictions imposed by civilian law, military rules of engagement, or ethical codes. Close combat using firearms or other distance weapons by military combatants at the tactical level is referred to in contemporary parlance as close-quarters battle. The United States Army uses the term combatives to describe various military fighting systems used in hand-to-hand combat training, systems which may incorporate eclectic techniques from several different martial arts and combat sports.

Ice fishing is the practice of catching fish with lines and fish hooks or spears through an opening in the ice on a frozen body of water. Ice fishers may fish in the open or in heated enclosures, some with bunks and amenities.
