Boden Fortress
Boden Fortress ( sv, Bodens fästning) is a modern fortification, fortress consisting of several major and minor forts and fortifications surrounding the city of Boden, Sweden, Boden, Norrbotten, in northern Sweden. The fortress was originally intended to stop or delay attacks from the east or coastal assaults, which at the time of construction meant Imperial Russia, Russian attacks launched from Grand Duchy of Finland, Finland. It was primarily the expansion of the railway net in Norrland, which in turn was a consequence of the rising importance of the northern iron ore fields, that led to the increased strategic value of northern Sweden and the construction of the fortress. Although the main forts were finished in 1908, many of the supporting fortifications were not completed until the start of the World War I, First World War. Improvements were also continuously made during, and between, both World Wars. Boden Fortress is made up of five primary self-supporting forts excavated o ...

Boden, Sweden
Boden (, outdatedly ) is a locality and the seat of Boden Municipality in Norrbotten County, Sweden with 16,847 inhabitants in 2018. It is part of the larger area around coastal city Luleå some southeast. After Kiruna, it is the second largest town in Northern Sweden's interior. History The town of Boden started as a railway junction where the Northern Line (''Norra stambanan'', opened 1894) met with the Ore Line (''Malmbanan'') from the rich iron ore fields in northern Sweden. The town experienced increased growth when the Boden Fortress was constructed in the beginning of the 20th century. The purpose of the fortress was to defend Sweden from a possible attack from the east, where Russia was considered the most dangerous threat. The first official writings about Boden, was in a 1500~ tax paper, where the mention of "Boden village" with 7 homes. Boden got the title of city in 1919.

World War
A world war is an international conflict which involves all or most of the world's major powers. Conventionally, the term is reserved for two major international conflicts that occurred during the first half of the 20th century, World WarI (1914–1918) and World WarII (1939–1945), although historians have also described other global conflicts as world wars, such as the Seven Years' War and the Cold War. Etymology The ''Oxford English Dictionary'' cited the first known usage in the English language to a Scottish newspaper, ''The People's Journal'', in 1848: "A war among the great powers is now necessarily a world-war." The term "world war" is used by Karl Marx and his associate, Friedrich Engels, in a series of articles published around 1850 called ''The Class Struggles in France''. Rasmus B. Anderson in 1889 described an episode in Teutonic mythology as a "world war" (Swedish: ''världskrig''), justifying this description by a line in an Old Norse epic poem, "Völuspá: fo ...

Ambush
An ambush is a long-established military tactics, military tactic in which a combatant uses an advantage of concealment or the element of surprise to attack unsuspecting enemy combatants from concealed positions, such as among dense underbrush or behind mountaintops. Ambushes have been used consistently throughout history, from ancient warfare, ancient to modern warfare. In the 20th century, an ambush might involve thousands of soldiers on a large scale, such as over a choke point such as a mountain pass, or a small irregulars band or insurgent group attacking a Regular army, regular armed force patrols. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack. Sometimes an ambush can involve the exclusive or combined use of improvised explosive devices, that allow the attackers to hit enemy convoys or patrols while minimizing the risk of being exposed to return fire. History This use by early people of ambushing may date as far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skirmish
Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They are usually deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing. A battle with only light, relatively indecisive combat is often called a skirmish even if heavier troops are sometimes involved. Skirmishers can be either regular army units that are temporarily detached to perform skirmishing or specialty units that are specifically armed and trained for such low-level irregular warfare tactics. Light infantry, light cavalry, and irregular units often specialize in skirmishing. Skirmishers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peripheral Defence
A peripheral or peripheral device is an auxiliary device used to put information into and get information out of a computer. The term ''peripheral device'' refers to all hardware components that are attached to a computer and are controlled by the computer system, but they are not the core components of the computer, such as the CPU or power supply unit. In other words, peripherals can also be defined as devices that can be easily removed and plugged into a computer system. Several categories of peripheral devices may be identified, based on their relationship with the computer: *An ''input device'' sends data or instructions to the computer, such as a mouse, keyboard, graphics tablet, image scanner, barcode reader, game controller, light pen, light gun, microphone and webcam; *An ''output device'' provides output data from the computer, such as a computer monitor, projector, printer, headphones and computer speaker; *An ''input/output device'' performs both input and output functi ...

Operational Mobility
In the field of military theory, the operational level of war (also called operational art, as derived from russian: оперативное искусство, or operational warfare) represents the level of command that connects the details of tactics with the goals of strategy. In Joint U.S. military doctrine, operational art is "the cognitive approach by commanders and staffs—supported by their skill, knowledge, experience, creativity, and judgment—to develop strategies, campaigns, and operations to organize and employ military forces by integrating ends, ways, and means." It correlates political needs and military power. Operational art is defined by its military-political scope, not by force size, scale of operations or degree of effort. Likewise, operational art provides theory and skills, and the operational level permits doctrinal structure and process. The operational level of war is concerned with four essential elements: time, space, means, and purpose. Through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

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
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
