strategy and tactics

strategy and tactics,

in warfare, related terms referring, respectively, to large-scale and small-scale planning to achieve military success. Strategy may be defined as the general scheme of the conduct of a war, tactics as the planning of means to achieve strategic objectives. Not all theorists of war make this a primary distinction. In the Chinese and Japanese traditions processes and paradoxes are emphasized more than categories (see Sun TzuSun Tzu

, described strategy as the planning of a whole campaign and tactics as the planning of a single battle. In Clausewitz's theory all military strategy is part of the larger political pattern, and all the nation's resources are to be subordinated to the task of attaining the political objective of the war; to this concerted effort he gave the name "grand strategy."

, an influential Swiss military theorist and general, regarded strategy as the art of moving forces to the field of battle and tactics as the conduct of forces in battle. Another school views strategy as a means of bringing the enemy to battle and tactics as the means of defeating him in battle. Some theorists focus on clear sets of general principles; some wrote books on principles, formations and maneuvers; and still others dwell on the importance of spirit or other intangibles.

 emerged as the outstanding field commander. His famous victory at Cannae (216 B.C.) over the Roman armies is still studied as an example of battlefield tactics. The study of military theory captured the imagination of several Byzantine emperors, who hoped to restore the glory of the Roman Empire. They studied the operations of the Roman legions and reduced the studies to what may be called the foundations of military science. Strategicon (c.578), compiled by Emperor Maurice, and Tactics (c.900), issued by Emperor Leo VI (Leo the Wise), are exhaustive treatises on the subject.

In Western Europe during the Middle Ages military science did not advance as quickly as its practice did, although siegecraft (see siegesiege,
assault against a city or fortress with the purpose of capturing it. The history of siegecraft parallels the development of fortification and, later, artillery. In early times battering rams and bores were employed to break down the walls and gates of a fortified place

, the leader of the Czech Hussites, in the early 15th cent. was particularly innovative. He adopted the wagon-fort as a unit of tactics, made artillery a maneuverable arm, and was the first commander to employ cavalry, infantry, and artillery in efficient tactical combination. He also espoused the principle that mobility is a better protection than armor.

 who, despite his mistakes, revolutionized the strategy and tactics of his time. Aided by a mass army, he made great use of the powerful shock attack, carefully planned in advance. He also introduced the loose formation, divisional organization, and the use of mobile, long-range artillery. Clausewitz's On War (1832) was an outgrowth of his studies of Napoleonic campaigns; it demonstrated the importance of destroying the enemy on the battlefield and downplayed the importance of the geometrical organization of troops in the field. Jomini's classic Précis de l'art de la guerre (1836), also influenced by a study of Napoleon's campaigns, had a different emphasis. Jomini stressed occupation of enemy territory through carefully planned geometric maneuvers while tactically he emphasized the importance of attacking. His work was influential and was part of the strategy during the U.S. Civil War. The main line of strategic theory, however, followed Clausewitz and culminated in the work of the Prussian-German school of H. K. von MoltkeMoltke, Helmuth Karl Bernhard, Graf von,
1800–1891, Prussian field marshal. Following his graduation from the Royal Military Academy of Denmark, he entered the Danish service, but resigned his commission in 1822 to join the Prussian army.

Modern Strategy and Tactics

Total War and Mechanized War

The first modern total war, fought with mass armies and modern firearms, was the U.S. Civil War. It demonstrated the importance of industrial mobilization; modern communications (especially railroads and the telegraph), and the deadly effect of new small armssmall arms,
firearms designed primarily to be carried and fired by one person and, generally, held in the hands, as distinguished from heavy arms, or artillery. Early Small Arms

. Beginning as a contest between armies, it grew into a conflict between two societies; before its termination almost the entire resources of both North and South were engaged.

The lessons of the U.S. Civil War were little noticed in Europe, where strategy and tactics continued to be thought of in terms of mid-19th-century practice. European theorists also ignored the extensive and effective use of machine guns, artilleryartillery,

, and rifles in the colonial wars of the 19th cent. As a result, the bloody stalemate of World War I came as a surprise to most generals. It was characterized by trench warfare and by bloody frontal attacks, which were usually stopped at great cost to the attackers by massed small arms and artillery fire. In an effort to break the stalemate, both sides turned to new technical devices, such as the tanktank, military,

Airpower, Nuclear Weapons, and Beyond

. Their theory of strategic bombing called for aerial attacks on the enemy's population and industrial centers to destroy the enemy's will and ability to continue fighting. In World War II that strategy was carried out in massive form by British and U.S. air forces in attacks on Germany and Japan. It was found, however, that aerial bombardment did not cut off industrial production and, in fact, strengthened the enemy's will to continue. In order to win the war the Allies had to conduct a number of campaigns with ground forces and, in the case of Germany, occupy the enemy's homeland.

Naval Strategy and Tactics

Naval strategy and tactics have been shaped by the forms and capabilities of naval warships (see navynavy,
originally, all ships of a nation, whether for war or commerce; the term navy now designates only such vessels as are built and maintained specifically for war. There have been three major developments in naval vessels. From ancient times to the late 16th cent.

). Geography is also an important factor in shaping naval thinking. In the Mediterranean, and for islands such as Britain, strong navies were crucial. For the many empires of the Middle East, the Central Asian steppes, or India, naval power was less important or superfluous. Not until Alfred T. MahanMahan, Alfred Thayer

 wrote The Influence of Sea Power upon History in the last decade of the 19th cent. was the central theme of naval strategy formulated in universal terms, although the British had been practicing it for hundreds of years. The main strategy of sea power was defined as "command of the sea," i.e., the ability to deny use of the sea as a means of transportation to an enemy while simultaneously protecting one's own merchant shipping, and the ability to use the sea to project power ashore while denying that capability to the enemy. Despite the introduction of new weapons such as steam warships, armored ships, heavy ordnance, submarines, and aircraft, "command of the sea" remained a fundamental objective of naval strategy. Another important naval strategy is "overseas presence," i.e., the visible display of seapower as a deterrent to intervention by opposing powers in key areas of international tension.

The development of airpower has led to a host of changes, including the emergence of aircraft carriers and naval air fleets and the development of submarine-based retaliatory missile forces. The employment of land-based and carrier-based aircraft during World War II showed that command of the seas rested in great part on control of the air above it. The submarine, introduced in World War I, greatly changed naval strategy and led to the development of many new weapons and tactics. In both world wars the submarine was employed mainly as a commerce destroyer and, as such, could not by itself gain command of the sea. However, the use of long-range guided missiles on nuclear-powered submarines in the 1960s transformed the submarine into a major weapon of strategic bombardment. Nuclear-powered submarines carrying guided missiles are almost invulnerable to attack.
