Mountain Howitzer
A howitzer () is a long-ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (moder ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Armed Forces
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States. From their inception during the American Revolutionary War, the U.S. Armed Forces have played a decisive role in the history of the United States. They helped forge a sense of national unity and identity through victories in the First Barbary War and the Second Barbary War. They played a critical role in the American Civil War, keeping the Confederacy from seceding from the republic and preserving the uni ...

Canon Obusier De 12
The Canon obusier de 12 (officially the "Canon obusier de campagne de 12 livres, modèle 1853"), also known as the "Canon de l’Empereur" ("emperor's cannon"), was a type of canon-obusier (literally "shell-gun cannon", "gun-howitzer") developed by France in 1853. Its performance and versatility (it was able to fire either ball, shell, canister or grapeshot) allowed it to replace all the previous field guns, especially the Canon de 8 and the Canon de 12 as well as the two howitzers of the Valée system. The cannon was known in the United States as the 12-pounder Napoleon after French President and Emperor Napoleon III. Characteristics The ''"canon obusier"'' was a smoothbore cannon firing either shells, balls, or canister. This was an improvement over previous cannon firing only balls, such as those of the Gribeauval system. The ''"canon obusier de 12 livres"'' is commonly described as a "12-pounder" in English, although the nominal rating was based on a slightly different meas ...

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, improvin ...

Licorne
Licorne (russian: Единорог, ''Yedinorog'', 'unicorn') is the French name of an 18th- and 19th-century Russian cannon, a type of muzzle-loading howitzer, devised in 1757 by M.W. Danilov and S.A. Martynov and accepted by artillery commander, general Peter Ivanovich Shuvalov. The licorne was a hybrid between the howitzers and guns of the era (a gun-howitzer), with a longer barrel than contemporary howitzers, giving projectiles a flatter trajectory, but longer range. Similar to the howitzers, they had a powder chamber of smaller diameter than the gun caliber, but whereas a howitzer's chamber was cylindrical, a licorne's was conical, with its base diameter the same as the gun bore. The conical chamber was easier to load and facilitated the placement of the projectile perfectly in the center of the barrel. Licornes were able to fire both the solid shot used for cannons and howitzer shells, as well as grapeshot and canister. The length of the barrel was 9 or 10 calibres, and ...

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

Ottoman Empire
The Ottoman Empire, * ; is an archaic version. The definite article forms and were synonymous * and el, Оθωμανική Αυτοκρατορία, Othōmanikē Avtokratoria, label=none * info page on book at Martin Luther University) // CITED: p. 36 (PDF p. 38/338) also known as the Turkish Empire, was an empire that controlled much of Southeast Europe, Western Asia, and Northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and, with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed the Conqueror. Under the reign of Suleiman the Magnificent, the Ottoman Empire marked the peak of its power and prosperity, as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abus Gun
The Abus gun ( tr, Obüs meaning ''howitzer'') is an early form of artillery created by the Ottoman Empire. They were small, but often too heavy to carry, and many were equipped with a type of tripod. They had a caliber between to and fired a projectile weighing 4.25 pounds. Abus guns, despite being a form of howitzer, were primarily used as an anti-infantry weapon. Development Its origins are not known. Early artillery such as this gun opened the way for the developments in artillery made across the ages, and spawned more recent and familiar types of artillery. By the Napoleonic era: Each regiment of foot artillery was made up of 10 cannons; four of the older, heavy and Sahi cannons, two of the older, lighter Abus guns and four of the new French-designed field guns... each of which came in a bewildering range of sizes. The ''Balyemez'' were massive, long-range guns...''Şahi'' was the Ottoman word for "field," and therefore Şahi artillery meant simply field artillery... The Ab ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Siege
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition warfare, attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to Surrender (military), surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "Investment (military), investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Fire
Direct fire or line-of-sight fire refers to firing of a ranged weapon whose projectile is launched directly at a target within the line-of-sight of the user. The firing weapon must have a sighting device and an unobstructed view to the target, which means no obstacles or friendly units can be between it and the target. A weapon engaged in direct fire conversely exposes itself to direct return fire from the target.p.49, Bailey This is in contrast to indirect fire, which refers to firing a projectile on a curved ballistic trajectory or delivering self-accelerated munitions capable of long range and various degrees of homing abilities to alter the flight path. Indirect fire does not need a direct line-of-sight to the target because the shots are normally directed by a forward observer. As such, indirect-fire weapons can shoot over obstacles or friendly units and the weapons can be concealed from counter-battery fire. Description Examples of direct-fire weapons include most anci ...
