Military campaign
In the military sciences, the term military campaign applies to large scale, long duration, significant military strategy plan incorporating a series of inter-related military operations or battles forming a distinct part of a larger conflict often called a war. The term derives from the plain of Campania, a place of annual wartime operations by the armies of the Roman Republic.
Definition
1.A military campaign denotes the time during which a given military force conducts combat operations in a given area (often referred to as AO, area of operation). A military campaign may be executed by either a single Armed Service, or as a combined services campaign conducted by land, naval, air, cyber and space forces.
2.The purpose of a military campaign is to achieve a particular desired resolution of a military conflict as its strategic goal. This is constrained by resources, geography and/or season. A campaign is measured relative to the technology used by the belligerents to achieve goals, and while in the pre-industrial Europe was understood to be that between the planting (late spring) and harvest times (late autumn), it has been shortened during the post-industrial period to a few weeks. However, due to the nature of campaign goals, usually campaigns last several months, or even a year as defined by Trevor N. Dupuy.
