Field Artillery Team
In the US system for land-based field artillery, the field artillery team is organized to direct and control indirect artillery fire on the battlefield. Since World War I, to conduct indirect artillery fire, three distinct components have evolved in this organization: the forward observer (FO), the fire direction center (FDC), and the firing unit, sometimes referred to as the gun line. On the battlefield, the field artillery team consists of some combinations of all of these elements. In other words, there may be multiple FOs calling in fire on multiple targets to multiple FDCs and any component may be in communication with some of the other elements depending on the situational requirements. History Modern artillery shoots at targets miles away, a hundredfold increase in range over 18th century guns, a result of development of rifled cannons, improvements in propellants, better communications, and technical improvements such as computing the aim. The enemy is engaged at such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carlos Brewer
Major General Carlos Brewer (5 December 1890 – 29 September 1976) was a United States Army officer who commanded the 12th Armored Division during World War II. After training the 12th Armored Division, he was not permitted to command the division in combat due to his age, so he requested his rank be reverted from major general to Colonel so that he could become an artillery officer in the European Theater of Operations (ETO). He innovated the method of field artillery targeting used in World War II, and implemented triangular organization of divisions. Early life Carlos Brewer was born on 5 December 1890 in Golo, Kentucky and attended West Kentucky College in Mayfield, Kentucky, until he entered United States Military Academy (USMA) at West Point, New York in 1909, graduating 15th in his class in 1913. Many of the graduates of the West Point Class of 1913 later became general officers, including Alexander Patch, Douglass T. Greene, Geoffrey Keyes, Willis D. Crittenberger, ...

Field Artillery
Field artillery is a category of mobile artillery used to support armies in the field. These weapons are specialized for mobility, tactical proficiency, short range, long range, and extremely long range target engagement. Until the early 20th century, field artillery were also known as foot artillery, for while the guns were pulled by beasts of burden (often horses), the gun crews would usually march on foot, thus providing fire support mainly to the infantry. This was in contrast to horse artillery, whose emphasis on speed while supporting cavalry units necessitated lighter guns and crews riding on horseback. Whereas horse artillery has been superseded by self-propelled artillery, field artillery has survived to this day both in name and mission, albeit with motor vehicles towing the guns (this towed artillery arrangement is often called mobile artillery), carrying the crews and transporting the ammunition. Modern artillery has also advanced to rapidly deployable wheeled a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Support Coordination Element
A fire support coordination element (FSCE) is a term used in the US Army to identify an element of military formation or unit organisation in which functions are directly related to positioning weapons and delivering their fire onto targets. The term is most often associated with artillery, but is sometimes used for Mortar (weapon), mortar fire. During the Vietnam War, the element, which included about five officers and nine enlisted personnel, collected and assessed information provided by the forward observers, field unit liaison officers, AN/TPS-25 surveillance radar section, division artillery air section, visual airborne target locator section, and the AN/MPQ-4 countermortar radar section (one in each direct support battalion).Nuclear Target Intelligence: whose responsibility, Lieutenant Colonel Samuel W.

Fire Discipline
Fire discipline is a system of communication in the military, primarily for directing artillery. By definition, fire discipline is the language of fire control. It consists of words, phrases, rules, and conventions which have specific meanings and which result in some definite action being taken with the guns. All ranks concerned in fire control must be thoroughly familiar with the language and the resulting actions. The aim of fire discipline is to ensure that in response to calls for fire (from a forward observer), the appropriate action is taken at the FPC (future planning cell), FSCC (fire support coordination center), FDC (fire direction center) and at the Guns/MRL, strictly in accordance with the intentions of the originator and with the minimum of delay. Six elements of a call for fire An initial call for fire (to an artillery battery) consists of six elements: *Observer identification *Warning order *Target location *Target description *Method of engagement *Method of ...

Field Artillery Branch (United States)
The Field Artillery Branch is a combat arms branch of the United States Army that is responsible for field artillery. Historical background The U.S. Army Field Artillery branch traces its origins to 17 November 1775 when the Continental Congress, unanimously elected Henry Knox "Colonel of the Regiment of Artillery". The regiment formally entered service on 1 January 1776. During the 19th Century a total of seven Artillery regiments were formed which contained a mixture of "heavy" artillery companies and "light" artillery batteries. The light artillery batteries took the role of field artillery although they did not use that designation. The seven artillery regiments were designated as regiments of artillery and were not distinguished as being either "coast" or "field" artillery as was the practice in the 20th Century. In the reorganization of the Army by the Act of 2 February 1901, the seven Artillery regiments were reorganized as the Artillery Corps. The Corps was split into ...

Friendly Fire
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy/hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire,Regan, Geoffrey (2002) ''Backfire: a history of friendly fire from ancient warfare to the present day'', Robson Books and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting. Use of the term "friendly" in a military context for allied personnel started during the First World War, often when shells fell short of the targeted enemy. The term ''friendly fire'' ...

Mount Suribachi
is a -high mountain on the southwest end of Iwo Jima in the northwest Pacific Ocean under the administration of Ogasawara Subprefecture, Tokyo Metropolis, Japan. The mountain's name derives from its shape, resembling a ''suribachi'' or grinding bowl. It is also known as , since the volcanic gas and water vapor that rolls in from the summit, alongside the rest of the island, give the appearance of a smoking pipe when viewed from the sea. Joe Rosenthal's iconic World War II photograph, '' Raising the Flag on Iwo Jima'', depicting United States Marines raising an American flag, was taken at the mountain's peak during the Battle of Iwo Jima in 1945. Ammunition ship USS ''Suribachi'' was named after this mountain. Geology Geologically, the mountain is a cinder cone of andesite, formed by volcanic activity. It is thought that the mountain is a dormant vent to a still active volcano (designated Iō-tō, the name of the island as a whole). From 1889 to 1957, the Japanese government ...

Iwo Jima
Iwo Jima (, also ), known in Japan as , is one of the Japanese Volcano Islands and lies south of the Bonin Islands. Together with other islands, they form the Ogasawara Archipelago. The highest point of Iwo Jima is Mount Suribachi at high. Although south of the metropolis of Tokyo on the mainland, this island of 21 km2 (8 square miles) is administered as part of the Ogasawara Subprefecture of Tokyo. Since July 1944, when all the civilians were forcibly evacuated, the island has had a military-only population. The island was the location of the Battle of Iwo Jima between February 1945 and March 1945. This engagement saw some of the fiercest fighting of the Pacific War, with each side suffering over 20,000 casualties in the battle. The island became globally recognized when Joe Rosenthal, of the Associated Press, published his photograph '' Raising the Flag on Iwo Jima'', taken on Mount Suribachi. The US military occupied Iwo Jima until 1968, when it was returned to ... [...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 ...

Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Angular Mil
A milliradian ( SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right). Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings (called an "mrad/mrad scope"), the shooter can use the reticle as a ruler to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling". Milliradian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
