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.[ citation needed ]
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. [1]
A quick guide to the size or scope of the offensive is to consider the number of troops involved in the side initiating the offensive.
Offensives are largely conducted as a means to secure initiative in a confrontation between opponents. They can be waged on land, at sea [2] or in the air.
A naval offensive, such as the Japanese attack on Pearl Harbor, can have wide-ranging implications for national strategies and require a significant logistical commitment to destroy enemy naval capabilities. It can also be used to interdict enemy shipping, such as World War II's Battle of the Atlantic. Naval offensives can also be tactical, such as Operation Coronado IX [3] conducted by the United States Navy's Mobile Riverine Force during the Vietnam War.
An air offensive is an operation that can describe any number of different types of operations, usually restricted to specific types of aircraft. The offensives conducted with the use of fighter aircraft are predominantly concerned with establishing air superiority in a given air space, or over a given territory. A bomber offensive is sometimes also known as a strategic bombing offensive and was prominently used by the Allies on a large scale during World War II. [4] Use of ground attack aircraft in support of ground offensives can be said to be an air offensive, such as that performed in the opening phase of the Red Army's Operation Kutuzov and Operation Polkovodets Rumyantsev, when hundreds of Il-2 aircraft were used en masse to overwhelm the Wehrmacht's ground troops.
A theatre offensive can be a war and a dominant feature of a national security policy, or one of several components of war if a country is involved in several theatres such as the United Kingdom in 1941. In general theatre, offensives require over 250,000 troops to be committed to combat operations, including combined planning for different arms and services of the armed forces, such as air defence troops integrated into the overall plan for ground operations. [5]
A strategic offensive is often a campaign and would involve the use of over 100,000 troops as part of a general strategy of the conflict in a given theatre. For example, the Operation Barbarossa was a theatre offensive composed of three distinct and inter-related campaigns in the Southern, Central and Northern parts of USSR territory. Soviet strategic offensive operations during World War II often involved multi-front coordinated operations. Along with the Wehrmacht operations on the Eastern Front of World War II, these were the largest military operations of the twentieth century. Strategic operations of the Red Army in World War II provides a listing of large-scale Soviet operations.
A strategic offensive is the aggressive expression of war planning and the use of strategic forces as a whole, combining all resources available for achieving defined and definitive goals that would fundamentally alter the balance of power between belligerents. [6] However, the planning and execution of strategic offensives are always based on theoretical considerations because it is impractical, uneconomic and difficult to hide a full-scale rehearsal of large-scale operations.
A strategic offensive consists of simultaneous, tandem or phased operational offensives that seek to achieve specific operational objectives that eventually lead to the achievement of a strategic goal, usually a complete defeat of the opposition, but also destruction of a significant enemy force or occupation of strategically significant territory, such as the Manchurian Strategic Offensive Operation. [7]
Any given strategic offensive is a derivative of a combination of factors such as national military doctrine, past military experience, and analysis of socio-political, economic and military circumstances. [8]
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish.
Blitzkrieg is a word used to describe a combined arms surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations; together with artillery, air assault, and close air support; with intent to break through the opponent's lines of defense, dislocate the defenders, unbalance the enemies by making it difficult to respond to the continuously changing front, and defeat them in a decisive Vernichtungsschlacht: a battle of annihilation.
The Battle of Kursk was a major World War II Eastern Front battle between the forces of Nazi Germany and the Soviet Union near Kursk in southwestern Russia during the summer of 1943, resulting in a Soviet victory. The Battle of Kursk was the single largest battle in the history of warfare. It, along with the Battle of Stalingrad several months earlier, are the two most oft-cited turning points in the European theatre of the war. It was one of the costliest and fiercest battles of the entire Second World War, and the single deadliest armoured battle in history and the opening day of the battle, 5 July, being the single costliest day in the history of aerial warfare. The battle was also marked by fierce house-to-house fighting and hand-to-hand combat.
Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking enemy installations or a concentration of enemy troops or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel.
Operation Bagration was the codename for the 1944 Soviet Byelorussian strategic offensive operation, a military campaign fought between 22 June and 19 August 1944 in Soviet Byelorussia in the Eastern Front of World War II, just over two weeks after the start of Operation Overlord in the west. It was during this operation that Nazi Germany was forced to fight simultaneously on two major fronts for the first time since the war began. The Soviet Union destroyed 28 of 34 divisions of Army Group Centre and completely shattered the German front line. The overall engagement is the largest defeat in German military history, with around 450,000 German casualties, while 300,000 other German soldiers were cut off in the Courland Pocket.
A military operation (op) is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives.
The Second Battle of Kharkov or Operation Fredericus was an Axis counter-offensive in the region around Kharkov against the Red Army Izium bridgehead offensive conducted 12–28 May 1942, on the Eastern Front during World War II. Its objective was to eliminate the Izium bridgehead over Seversky Donets or the "Barvenkovo bulge" which was one of the Soviet offensive's staging areas. After a winter counter-offensive that drove German troops away from Moscow but depleted the Red Army's reserves, the Kharkov offensive was a new Soviet attempt to expand upon their strategic initiative, although it failed to secure a significant element of surprise.
A counterattack is a tactic employed in response to an attack, with the term originating in "war games". The general objective is to negate or thwart the advantage gained by the enemy during attack, while the specific objectives typically seek to regain lost ground or destroy the attacking enemy.
In current military use, combined operations are operations 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.
The first Battle of Smolensk was a battle during the second phase of Operation Barbarossa, the Axis invasion of the Soviet Union, in World War II. It was fought around the city of Smolensk between 10 July and 10 September 1941, about 400 km (250 mi) west of Moscow. The Ostheer had advanced 500 km (310 mi) into the USSR in the 18 days after the invasion on 22 June 1941.
In the field of military theory, the operational level of war represents the level of command that connects the details of tactics with the goals of strategy.
Principles of war are rules and guidelines that represent truths in the practice of war and military operations.
Deep operation, also known as Soviet deep battle, was a military theory developed by the Soviet Union for its armed forces during the 1920s and 1930s. It was a tenet that emphasized destroying, suppressing or disorganizing enemy forces not only at the line of contact but also throughout the depth of the battlefield.
The Soviet–Japanese War was a campaign of the Second World War that began with the Soviet invasion of Manchuria following the Soviet declaration of war against Japan on 8 August 1945. The Soviet Union and Mongolian People's Republic toppled the Japanese puppet states of Manchukuo in Manchuria and Mengjiang in Inner Mongolia, as well as northern Korea, Karafuto on the island of Sakhalin, and the Kuril Islands. The defeat of Japan's Kwantung Army helped bring about the Japanese surrender and the end of World War II. The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it was made apparent that the Soviet Union was not willing to act as a third party in negotiating an end to hostilities on conditional terms.
Russian military deception, sometimes known as maskirovka, is a military doctrine developed from the start of the 20th century. The doctrine covers a broad range of measures for military deception, from camouflage to denial and deception.
Expeditionary warfare is a military invasion of a foreign territory, especially away from established bases. Expeditionary forces were in part the antecedent of the modern concept of rapid deployment forces. Traditionally, expeditionary forces were essentially self-sustaining with an organic logistics capability and with a full array of supporting arms.
An air offensive is a type of military operation conducted using aircrew, airborne and strategic missile troops to allow securing of war, campaign or operational initiative, air-space superiority or ensure defeat of enemy forces through use of air-delivered ordnance, or destruction of enemy air, ground and naval forces.
A naval offensive is the aggressive deployment of naval forces during a military campaign to strategically, operationally or tactically provide secure use of shipping routes, or coastal regions for friendly shipping, or deny them to enemy shipping.
Military art is a field of theoretical research and training methodology in military science used in the conduct of military operations on land, in the maritime or air environments. Military art includes the study and application of the principles of warfare and laws of war that apply equally to the closely interrelated military strategy, operational art and tactics. Exercise of military art is highly dependent on the economics and logistics supporting the armed forces, their military technology and equipment, and reflects the social influences on the military organisation exercising military art. Often misunderstood due to its 19th-century perception as generally "including the entire subject of war", it is primarily, as the term implies, the expression of creative thinking on the part of the decision-makers in employing their forces, with the map of the area of operations as a veritable canvas, and the movement of forces commonly marked on the map with arrows, as brush strokes. Less imaginatively it was defined in France during the 19th century as
The art of war is the art of concentrating and employing, at the opportune moment, a superior force of troops upon the decisive point.
The Soviet invasion of South Sakhalin, also known as the Battle of Sakhalin, was the Soviet invasion of the Japanese portion of Sakhalin Island known as Karafuto Prefecture. The invasion was part of the Soviet–Japanese War, a minor campaign in the Asian Theatre during Second World War.
