Military history is the study of armed conflict in the history of humanity, and its impact on the societies, cultures and economies thereof, as well as the resulting changes to local and international relationships.
Professional historians normally focus on military affairs that had a major impact on the societies involved as well as the aftermath of conflicts, while amateur historians and hobbyists often take a larger interest in the details of battles, equipment, and uniforms in use.

A counterattack is a tactic employed in response to an attack, with the term originating in "war games". The general objective is to negate or thwart the advantage gained by the enemy during attack, while the specific objectives typically seek to regain lost ground or destroy the attacking enemy (this may take the form of an opposing sports team or military units).
A counter-offensive is a broad-scale counterattack. The counter-offensive is executed after exhausting the enemy's frontline troops and after the enemy reserves had been committed to combat and proven incapable of breaching defenses, but before the enemy has had the opportunity to assume new defensive positions. Sometimes the counter-offensive can be of a more limited operational maneuver nature, with more limited objectives rather than those seeking attainment of a strategic goal. A counter-offensive was considered by Clausewitz to be the most efficient means of forcing the attacker to abandon offensive plans. Counter-offensives can be executed not only on land, but also by the naval, and air forces. Strategic counter-offensives have been recorded by military historians in many wars throughout military history. Although not always known as such, because they are usually described by historians in conjunction with the defensive phase, such as the Battle of Moscow.
