Operational warfare in the context of "Raid (military)"

The artillery of World War I, improved over that used in previous wars, influenced the tactics, operations, and strategies that were used by the belligerents. This led to trench warfare and encouraged efforts to break the resulting stalemate at the front. World War I raised artillery to a new level of importance on the battlefield.

The First World War saw many developments in artillery warfare. Artillery could now fire the new high explosive shells, and throw them farther and at a higher rate of fire. Because of this, enemies in trenches were no longer always safe, and could constantly be fired upon. In some areas, artillery concentration was common, with several guns firing onto an area such as a line of trenches, each gun firing several rounds per minute for hours. Artillery barrages were also used to divert the enemy's attention from the site of attack before a battle. Paths behind the lines were also fired on so that enemy reinforcements could not safely reach the front lines.

An offensive is a military operation that seeks through an aggressive projection of armed forces to occupy or recapture territory, gain an objective or achieve some larger strategic, operational, or tactical goal. Another term for an offensive often used by the media is "invasion", or the more general "attack". An offensive is a conduct of combat operations that seek to achieve only some of the objectives of the strategy being pursued in the theatre as a whole. Commonly an offensive is carried out by one or more divisions, numbering between 10 and 30,000 troops as part of a combined arms manoeuvre.

The offensive was considered a pre-eminent means of producing victory, although with the recognition of a defensive phase at some stage of the execution.

In current military use, combined operation is a operation conducted by forces of two or more allied nations acting together for the accomplishment of a common strategy, a strategic and operational and sometimes tactical cooperation. Interaction between units and formations of the land, naval and air forces, or the cooperation between military and civilian authorities in peacekeeping or disaster relief operations is known as joint operations or interoperability capability.
