Flexible Defense
The flexible defense is a military theory about the design of modern fortifications. The examples of "flexible" defense-lines ( Mannerheim Line, Árpád Line, Bar Lev Line) are not based on dense lines of heavily armed, large and expensive concrete fortifications as the systems such as the Maginot Line were. Their protective capacity hinges on multiple lines of obstacles and small shelters fitting into the environment. They are "flexible" because soldiers are not locked in pillboxes, but fight instead in easily replaceable open earth-wood made positions, while bunkers serve only as shelters during bombardments. As a result, they are able to adapt to the opponent's movements, and there are no easily targeted large buildings in these lines. Theoretical background The methodology was first used by the Finnish military in the Mannerheim line, but had been drawn up in detail by General Teofil Hárosy, the Hungarian pioneer, in 1939–1940. The protective capacity would be pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All Round Defence
All-around defense or perimeter defense is a type of defensive fighting position intended to give military units the ability to repel attacks from any direction. The positioning of the outer defensive fighting positions of a unit, is circular or triangular,http://www.marines.mil/news/publications/Documents/FM%203-21.8%20%20The%20Infantry%20Rifle%20Platoon%20and%20Squad_5.pdf "The trace of the platoon is circular or triangular rather than linear" from a bird's-eye view. One version consists of soldiers forming a wide circle around the soldier in charge (and radioman etc.) with a spacing typically of 3–4 metres between each person (on the circle's circumference). When a group of soldiers relocate as a part of a defensive operation, a perimeter defense can be temporarily maintained without cover.

Battalion
A battalion is a military unit, typically consisting of 300 to 1,200 soldiers commanded by a lieutenant colonel, and subdivided into a number of companies (usually each commanded by a major or a captain). In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations. The word battalion came into the English language in the 16th century from the French language ( French: ''bataillon'' meaning "battle squadron"; Italian: ''battaglione'' meaning the same thing; derived from the Vulgar Latin word ''battalia'' meaning "battle" and from the Latin word ''bauttere'' meaning "to beat" or "to strike"). The first use of the word in English was in the 1580s. Description A battalion comprises two or more primary mission companies which are often of a common type (e.g., infantry, tank, or maintenance), although there are exceptions such as combined arms battalions in the U.S. Army. In addition to the primary mission companies, a battal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Company (military Unit)
A company is a military unit, typically consisting of 80–250 soldiers and usually commanded by a major or a captain. Most companies are formed of three to seven platoons, although the exact number may vary by country, unit type, and structure. Usually several companies are grouped as a battalion or regiment, the latter of which is sometimes formed by several battalions. Occasionally, ''independent'' or ''separate'' companies are organized for special purposes, such as the 1st Air Naval Gunfire Liaison Company or the 3rd Force Reconnaissance Company. These companies are not organic to a battalion or regiment, but rather report directly to a higher level organization such as a Marine Expeditionary Force headquarters (i.e., a corps-level command). Historical background The modern military company became popularized during the reorganization of the Swedish Army in 1631 under King Gustav II Adolph. For administrative purposes, the infantry was divided into companies consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragon's Teeth (fortification)
Dragon's teeth (german: Drachenzähne) are square-pyramidal fortifications of reinforced concrete first used during the Second World War to impede the movement of tanks and mechanised infantry. The idea was to slow down and channel tanks into killing zones where they could easily be disposed of by anti-tank weapons. They were employed extensively, particularly on the Siegfried Line. World War II Dragon's teeth were used by several armies in the European Theatre. The Germans made extensive use of them on the Siegfried Line and the Atlantic Wall. Typically, each tooth was tall. Land mines were often laid between teeth, and further obstacles were constructed along the lines of teeth, such as barbed wire to impede infantry or diagonally-placed steel beams to further hinder tanks. Many were laid in the United Kingdom in 1940–1941, as part of the effort to strengthen the country's defences against a possible German invasion. Due to the huge numbers laid and their durable ...

Anti-tank Trench
Anti-tank trenches, also called anti-tank ditches, are ditches dug into and around fortified positions to hold up the advance of enemy tanks. Anti-tank ditches were first used in World War I by Germany in an effort to protect their trenches against the newly developed British and French tanks. An anti-tank ditch has to be wide enough and deep enough to prevent a tank from crossing. Armies have been known to disguise anti-tank ditches to enable the ditch to disable an enemy tank. Anti-tank trenches can be defeated by use of a fascine. Anti-tank ditches can also be crossed by use of bridges either laid by armoured vehicles or built over them, they can also be defeated by demolition of each side, using explosives, to make inclines that can be cossed or can be filled in by earth moving equipment. According to the United States Army, there are several methods by which combat engineers can dig an anti-tank ditch on the battlefield. Using only hand tools, a platoon of soldiers can dig a ...

Platoon
A platoon is a military unit typically composed of two or more squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 50 people, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a commissioned officer. The platoon leader is usually a junior officer—a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Rifle platoons normally consist of a small platoon headquarters and three or four sections (Commonwealth) or squads (United States). In some armies, platoon is used throughout the branches of the army. In a few armies, such as the French Army, a platoon is specifically a cavalry unit, and the infantry use "section" as the equivalent unit. A unit consisting of several platoons is called a company or a battery. Etymology According to Merriam-Webster, "The term was first used in th ...

Air-raid Shelter
Air raid shelters are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack (but many have been used as defensive structures in such situations). During World War II, many types of structures were used as air raid shelters, such as cellars, Hochbunkers (in Germany), basements, and underpasses. Bombing raids during World War I led the UK to build 80 specially adapted London Underground stations as shelters. However, during World War II, the government initially ruled out using these as shelters. After Londoners flooded into underground stations during The Blitz, the government reversed its policy. The UK began building street communal shelters as air raid shelters in 1940. Anderson shelters, designed in 1938 and built to hold up to six people, were in common use in the UK. Indoor shelters known as Morrison shelters were int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defensive Fighting Position
A defensive fighting position (DFP) is a type of earthwork constructed in a military context, generally large enough to accommodate anything from one soldier to a fire team (or similar sized unit). Terminology Tobruk type positions are named after the system of defensive positions constructed, initially, by the Italian Army at Tobruk, Libya. After Tobruk fell to the Allies in January 1941, the existing positions were modified and significantly expanded by the Australian Army which, along with other Allied forces, reused them in the Siege of Tobruk. A foxhole is one type of defensive strategic position. It is a "small pit used for cover, usually for one or two personnel, and so constructed that the occupants can effectively fire from it". It is known more commonly within United States Army slang as a "fighting position" or as a "ranger grave". It is known as a "fighting hole" in the United States Marine Corps, a "gun-pit" in Australian Army terminology, and a "fighting pit ...

Military Engineering
Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes other engineering disciplines such as mechanical and electrical engineering techniques. According to NATO, "military engineering is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment. Military engineering incorporates support to maneuver and to the force as a whole, including military engineering functions such as engineer support to force protection, counter-improvised explosive devices, environmental protection, engineer intelligence and military search. Military engineering does not encompass the activities undertaken by those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armoured Vehicle-launched Bridge
An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as (and primarily) rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines), when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located (or sufficiently sturdy, a substantial concern when moving 60-ton tanks). The bridge layer unfolds and launches its cargo, providing a ready-made bridge across the obstacle in only minutes. Once the span has been put in place, the AVLB vehicle detaches from the bridge, and moves aside to allow traffic to pass. Once all of the ve ...

Sapper
A sapper, also called a pioneer (military), pioneer or combat engineer, is a combatant or soldier who performs a variety of military engineering duties, such as breaching fortifications, demolitions, bridge-building, laying or clearing minefields, preparing field defenses, and road and airfield construction and repair. They are also trained and equipped to serve as provisional infantry, fighting as such as a secondary mission. A sapper's duties facilitate and support movement, defense, and survival of allied forces and impede those of enemies. The term "sapper" is used in the British Army and Commonwealth of Nations, Commonwealth nations and the U.S. military. The word "sapper" comes from the French word ''sapeur'', itself being derived from the verb ''saper'' (to undermine, to dig under a wall or building to cause its collapse). Historical origin Sapping A sapper, in the sense first used by the French military, was one who dug trenches to allow besieging forces to advance ...
