Fire and movement

Fire and movement, or fire and maneuver, is the basic modern military low-level unit tactic used to maneuver on the battlefield in the presence of the enemy, especially when under fire. It involves heavy use of all available cover, and highly-coordinated exchanges of rapid movement by some elements of the squad or platoon while other elements cover this movement with suppression fire. It is used both to advance on enemy positions as part of an attack, or withdrawal from current positions under attack by the enemy. The moving and supporting (suppressing) elements may be teams or individuals, and may quickly and continuously exchange roles until the entire unit completes the maneuver objective. Some members will specialize more in different roles within fire and movement as fits their range, equipment, terrain, and ability to maneuver. This is usually applied to standard infantry tactics, but forms of this are also used with armored fighting vehicles or when supported by artillery or airpower. The Swedish king Gustavus Adolphus was likely the first to use the tactic in wartime, in the Thirty Years' War, against his Habsburg opponents. Fire and movement became particularly important when more and more rifled muskets and breech-loading weapons, later followed by machine guns, were fielded on the battlefields of the 19th century. The increased accuracy, range and rate of fire translated into more firepower, allowing smaller units to operate more independently. This marked the transition from first- to second-generation warfare that saw the increasing application of fire and movement on the tactical level. During the First Boer War, it was a standard Boer tactic, and contributed to a series of victories, culminating at the Battle of Majuba Hill. According to Stephen Biddle, the effective use of fire and maneuver was the key to ending the stalemates on the lines of the Western Front during the final months of World War I. Since that time, he argues, mastery of fire and maneuver has been one of the central components of successful military tactics in modern land warfare.
