War Effort
War effort is a coordinated mobilization of society's resources—both industrial and civilian—towards the support of a military force, particular during a state of war. Depending on the militarization of the culture, the relative size of the armed forces and the society supporting them, the style of government, and the famous support for the military objectives, such war effort can range from a small industry to complete command of society. Although many societies were retroactively perceived to be engaged in a war effort, the concept was not generally used until the last decade of the 18th century, when the leaders of the French Revolution called for the ''levée en masse'' and a general mobilization of society to prevent monarchist forces from reclaiming control of the French government. The concept was subsequently adapted and used by Russia, the United Kingdom, and the United States, especially during World War I and World War II. The term ''war effort'' was c ...

Raid (military)
Raiding, also known as depredation, is a military tactics, military tactic or operational warfare "smash and grab" mission which has a specific purpose. Raiders do not capture and hold a location, but quickly retreat to a previous defended position before enemy forces can respond in a coordinated manner or formulate a counter-attack. Raiders must travel swiftly and are generally too lightly equipped and supported to be able to hold ground. A raiding group may consist of combatants specially trained in this tactic, such as commandos, or as a special mission assigned to any Regular army, regular troops. Raids are often a standard tactic in irregular warfare, employed by warriors, guerrilla warfare, guerrilla fighters or other irregular military forces. Some raids are large, for example the Sullivan Expedition. The purposes of a raid may include: * to demoralization (warfare), demoralize, confuse, or exhaust the enemy; * to destroy specific goods or installations of military or econo ...

Morale
Morale ( , ) is the capacity of a group's members to maintain belief in an institution or goal, particularly in the face of opposition or hardship. Morale is often referenced by authority figures as a generic value judgment of the willpower, obedience, and self-discipline of a group tasked with performing duties assigned by a superior. According to Alexander H. Leighton, "morale is the capacity of a group of people to pull together persistently and consistently in pursuit of a common purpose". With good morale, a force will be less likely to give up or surrender. Morale is usually assessed at a collective, rather than an individual level. In wartime, civilian morale is also important. Definition Military history experts have not agreed on a precise definition of "morale". Clausewitz's comments on the subject have been described as "deliberately vague" by modern scholars. George Francis Robert Henderson, a widely read military author of the pre-World War I era, viewed mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...

Aristocracy
Aristocracy (; ) is a form of government that places power in the hands of a small, privileged ruling class, the aristocracy (class), aristocrats. Across Europe, the aristocracy exercised immense Economy, economic, Politics, political, and social influence. In Western Christian countries, the aristocracy was mostly equal with magnates, also known as the titled or higher nobility, however the members of the more numerous social class, the untitled lower nobility (petty nobility or gentry) were not part of the aristocracy. Classical aristocracy In ancient Greece, the Greeks conceived aristocracy as rule by the best-qualified citizens—and often contrasted it favorably with monarchy, rule by an individual. The term was first used by such ancient Greeks as Aristotle and Plato, who used it to describe a system where only the best of the citizens, chosen through a careful process of selection, would become rulers, and hereditary monarchy, hereditary rule would actually have been f ...

Peasant
A peasant is a pre-industrial agricultural laborer or a farmer with limited land-ownership, especially one living in the Middle Ages under feudalism and paying rent, tax, fees, or services to a landlord. In Europe, three classes of peasants existed: non-free slaves, semi-free serfs, and free tenants. Peasants might hold title to land outright (fee simple), or by any of several forms of land tenure, among them socage, quit-rent, leasehold, and copyhold. In some contexts, "peasant" has a pejorative meaning, even when referring to farm laborers. As early as in 13th-century Germany, the concept of "peasant" could imply "rustic" as well as "robber", as the English term villain/villein. In 21st-century English, the word "peasant" can mean "an ignorant, rude, or unsophisticated person". The word rose to renewed popularity in the 1940s–1960s as a collective term, often referring to rural populations of developing countries in general, as the "semantic successor to 'native', ...

Feudal
Feudalism, also known as the feudal system, was a combination of legal, economic, military, cultural, and political customs that flourished in Middle Ages, medieval Europe from the 9th to 15th centuries. Broadly defined, it was a way of structuring society around relationships derived from the holding of land in exchange for service or labour. The classic definition, by François Louis Ganshof (1944),François Louis Ganshof (1944). ''Qu'est-ce que la féodalité''. Translated into English by Philip Grierson as ''Feudalism'', with a foreword by F. M. Stenton, 1st ed.: New York and London, 1952; 2nd ed: 1961; 3rd ed.: 1976. describes a set of reciprocal legal and Medieval warfare, military obligations of the warrior nobility and revolved around the key concepts of lords, vassals, and fiefs. A broader definition, as described by Marc Bloch (1939), includes not only the obligations of the warrior nobility but the obligations of all three estates of the realm: the nobility, the cl ...
