Artillery Observer
An artillery observer, artillery spotter or forward observer (FO) is responsible for directing artillery and mortar fire onto a target. It may be a ''forward air controller'' (FAC) for close air support (CAS) and spotter for naval gunfire support (NGSF). Also known as fire support specialist (FiSTer), an artillery observer usually accompanies a tank or infantry maneuver unit. Spotters ensure that indirect fire hits targets which the troops at the fire support base cannot see. Because artillery is an indirect fire weapon system, the guns are rarely in line-of-sight of their target, often located miles away. The observer serves as the eyes of the guns, by sending target locations and if necessary corrections to the fall of shot, usually by radio. More recently, a mission controller for an Army Unmanned Air System (UAS) may also perform this function, and some armies use special artillery patrols behind the enemy's forward elements. Special forces such as the British SAS, US S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Observation Balloon
An observation balloon is a type of balloon that is employed as an aerial platform for intelligence gathering and artillery spotting. Use of observation balloons began during the French Revolutionary Wars, reaching their zenith during World War I, and they continue in limited use today. Synonyms include espionage balloon, reconnaissance balloon, or surveillance balloon. Historically, observation balloons were filled with hydrogen. The balloons were fabric envelopes filled with hydrogen gas, whose flammable nature led to the destruction of hundreds of balloons on both sides. Observers manning these observation balloons frequently had to use a parachute to evacuate their balloon when it came under attack. To avoid the potentially flammable consequences of hydrogen, observation balloons after World War I were often filled with non-flammable helium. Typically, balloons were tethered to a steel cable attached to a winch that reeled the gasbag to its desired height (usually 1,000-1,5 ...

Forward Air Control
Forward air control is the provision of guidance to close air support (CAS) aircraft intended to ensure that their attack hits the intended target and does not injure friendly troops. This task is carried out by a forward air controller (FAC). A primary forward air control function is ensuring the safety of friendly troops during close air support. Enemy targets in the front line ("Forward Edge of the Battle Area" in US terminology) are often close to friendly forces and therefore friendly forces are at risk of friendly fire through proximity during air attack. The danger is twofold: the bombing pilot cannot identify the target clearly, and is not aware of the locations of friendly forces. Camouflage, a constantly changing situation and the fog of war all increase the risk. Present day doctrine holds that Forward Air Controllers (FACs) are not needed for air interdiction, although there has been such use of FACs in the past. An additional concern of forward air controllers is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fall Of Shot
Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles. Description There are two dimensions in aiming a weapon: * In the horizontal plane (azimuth); and * In the vertical plane (elevation), which is governed by the distance (range) to the target and the energy of the propelling charge. The projectile trajectory is affected by atmospheric conditions, the velocity of the projectile, the difference in altitude between the firer and the target, and other factors. Direct fire sights may include mechanisms to compensate for some of these. Handguns and rifles, machine guns, anti-tank guns, tank main guns, many types of unguided rockets (although missiles, mortars, howitzers, rocket artillery, multiple rocket launchers, and artillery in ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE ...

Army Air Corps (United Kingdom)
The Army Air Corps (AAC) is a component of the British Army, first formed in 1942 during the Second World War by grouping the various airborne units of the British Army. Today, there are eight regiments (seven Regular Army and one Reserve) of the AAC as well as four Independent Flights and two Independent Squadrons deployed in support of British Army operations around the world. Regiments and flights are located in the United Kingdom, Brunei, Canada, and Germany. Some AAC squadrons provide the air assault elements of 16 Air Assault Brigade through Joint Helicopter Command. History First formation: 1942–1949 The British Army first took to the sky during the 19th century with the use of observation balloons. In 1911 the Air Battalion of the Royal Engineers was the first heavier-than-air British military aviation unit. The following year, the battalion was expanded into the Military Wing of the Royal Flying Corps which saw action throughout most of the First World War ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security" ...

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the main 75 mm gun into a fully traversing central turret. One feature, a one-axis gyrostabilizer, was not precise enough to allow firing when moving but did help keep the gun aimed in rou ...
