The term military campaign applies to large scale, long duration, significant military strategy plans 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.
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 up to a year as defined by Trevor N. Dupuy.
Conduct of campaigns
The success of a military campaign is evaluated based on the degree of achievement of planned goals and objectives through combat and noncombat operations. This is determined when one of the belligerent military forces defeats the opposing military force within the constraints of the planned resource, time and cost allocations. The manner in which a force terminates its operations often influences the public perception of the campaign's success. A campaign may end in conquest, and be followed by the transition of military authority to a civil authority and the redeployment of forces, or a permanent installation of a military authority in the occupied area.
Military campaigns, inside and outside defined wars, may exceed the original or even revised planning parameters of scope, time and cost. Such stalled campaigns, for example the western front in World War I, were formerly called "stalemates" but in the late 20th century the metaphor of a quagmire was often applied. Such a situation may arise of various factors such as:
