is a state of conflict
between relatively large groups of people (such as nations
, social groups
), which is characterized by the use of armed lethal violence
or upon civilians
. Other terms for war, which often serve as euphemisms
, include armed conflict, hostilities, and police action
A common perception of war is a series of military campaigns between at least two or more opposing sides involving a dispute over sovereignty, territory, resources, ideology or a host of other issues. A war to liberate an occupied country is sometimes characterised as a "war of liberation", while a war between internal elements of the same state may constitute a civil war.
Aside from humans and their primate brethren, ants are the only other species known to exhibit such behavior on a large scale.
A battle is a single engagement fought between two or more parties, wherein each party or aligned group will seek to defeat their opponent. Battles are most often fought during military campaigns and can usually be well defined in time, space and action. Wars are generally the continuum of a related series of battles and are guided by strategy, whereas individual battles are the stage on which tactics are employed.
Military history is the recording of those events in the history of humanity that fall within the category of organised armed conflict.
The Webley Revolver
was, in various marks, the standard-issue service pistol
for the armed forces of the United Kingdom
, the British Empire
, and the Commonwealth
from 1887 until 1963. The Webley is a top-break
revolver with automatic extraction; breaking the revolver open for reloading also operates the extractor
, removing the spent cartridges
from the cylinder
. The Webley Mk I service revolver was adopted in 1887, but it was a later version—the Mk IV—which rose to prominence during the Boer War
of 1899–1902. The Mk VI, introduced in 1915 during World War I
, is perhaps the best-known model. Webley service revolvers are among the most powerful top-break revolvers ever produced, firing the .455 Webley
cartridge. Although the .455 calibre Webley is no longer in military service, the .38/200
Webley Mk IV variant is still sporadically in use as a police sidearm in a number of countries.
