M198 Howitzer
The M198 is a medium-sized, towed 155 mm artillery piece, developed for service with the United States Army and Marine Corps. It was commissioned to be a replacement for the World War II-era M114 155 mm howitzer. It was designed and prototyped at the Rock Island Arsenal in 1969 with firing tests beginning in 1970 and went into full production there in 1978. It entered service in 1979 and since then 1,600 units have been produced. The M198 was replaced in US and Australian service by the M777 howitzer. Description The M198 155 mm howitzer weighs less than , allowing it to be dropped by parachute or transported by a CH-53E Super Stallion or CH-47 Chinook. The M198 is towed by a truck that is used to carry the nine person crew with supplies and ammunition; it is transported tail first. The gun tube can be rotated over the howitzer's trail legs to reduce its length, though this requires removal of the muzzle brake, or left in the firing position for faster deployment. When f ...

Airborne Forces
Airborne forces are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers. The main advantage of airborne forces is their ability to be deployed into combat zones without a land passage, as long as the airspace is accessible. Formations of airborne forces are limited only by the number and size of their transport aircraft; a sizeable force can appear "out of the sky" behind enemy lines in merely hours if not minutes, an action known as ''vertical envelopment''. Airborne forces typically lack enough supplies for prolonged combat and so they are used for establishing an airhead to bring in larger forces before carrying out other combat objectives. Some infantry fighting vehicles have also been modified for paradropping with infantry to provide heavier firepower. Protocol I of the Geneva Conventions protects parachutis ...

Light Infantry
Light infantry refers to certain types of lightly equipped infantry throughout history. They have a more mobile or fluid function than other types of infantry, such as heavy infantry or line infantry. Historically, light infantry often fought as Reconnaissance, scouts, Raid (military), raiders, and skirmishers. These are loose formations that fight ahead of the main army to harass, delay, disrupt supply lines, engage the enemy's own skirmishing forces, and generally "soften up" an enemy before the main battle. Light infantrymen were also often responsible for Screening (tactical), screening the main body of a military formation. Following World War II, the term "light infantry" has evolved to include rapid-deployment units (including commando and Airborne forces, airborne units) that emphasize speed and mobility over armor and firepower. Some units or battalions that historically held a skirmishing role retain their designation "light infantry" for the sake of tradition. His ...

Battalion
A battalion is a military unit, typically consisting of up to one thousand soldiers. A battalion is commanded by a lieutenant colonel and subdivided into several Company (military unit), companies, each typically commanded by a Major (rank), major or a Captain (armed forces), captain. The typical battalion is built from three operational companies, one weapons company and one headquarters company. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations. The word ''battalion'' has its origins in the Late Latin word ''battalion'', which is derived from ''battalia'', meaning "battle" or "combat." The term was used to describe a large group of soldiers ready for battle. Over time, its meaning evolved in military terminology. The word "battalion" came into the English language in the 16th century from the French language, French , meaning "battle squadron" (similar to the Italian language, Italian meaning the same thing) and ...

Military Organization
Military organization (American English , AE) or military organisation (British English , BE) is the structuring of the armed forces of a State (polity), state so as to offer such military capability as a military policy, national defense policy may require. Formal military organization tends to use hierarchical forms (see Military organization#Modern hierarchy , Modern hierarchy for terminology and approximate troop strength per hierarchical unit). In some countries, paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as Insurgency, insurgent forces, often emulate military organizations, or use these structures. History The use of formalized Military rank, ranks in a hierarchical structure came into widespread use with the Roman Army. The Roman Army was organized into Roman legion, legions, each comprising around 5000 soldiers and led by a Legate (anc ...

Corps
Corps (; plural ''corps'' ; from French , from the Latin "body") is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was formally introduced March 1, 1800, when Napoleon ordered General Jean Victor Marie Moreau to divide his command into four corps. The size of a corps varies greatly, but two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense. Within military terminology a corps may be: *an military organization, operational formation, sometimes known as a field corps, which consists of two or more division (military), divisions, such as the I Corps (Grande Armée), , later known as ("First Corps") of Napoleon I's ); *an administrative corps (or Muster (military), mustering) – that is a #Administrative corps, specialized branch of a military service (such as an artillery corps, an armoured corps, a signal corps, a medical corps, a marine corps, or a corps of ...

Rocket-assisted Projectile
A rocket-assisted projectile (RAP) is a cannon, howitzer, Mortar (weapon), mortar, or recoilless rifle round incorporating a rocket motor for independent propulsion. This gives the projectile greater speed and range than a non-assisted Ballistics, ballistic shell, which is propelled only by the gun's exploding charge. Some forms of rocket-assisted projectiles can be outfitted with a laser guide for greater accuracy. History The German 15 cm sFH 18 howitzer was the first artillery piece to make use of RAP rounds with the objective of replacing the 10 cm schwere Kanone 18 by making the howitzer range equal or superior to the 10 cm sK 18, freeing up production capacity for more important weapons. Issued in 1941, the 15cm R Gr 19 FES shell achieved a maximum range of , but it wasn't entirely successful and withdrawn from service shortly after. Ultimately, it proved to be a little more than an experimental design: the instruction manuals and warnings included did nothing to imbue the ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article o ...

CH-47 Chinook
The Boeing CH-47 Chinook is a tandem-rotor helicopter originally developed by American rotorcraft company Piasecki Helicopter, Vertol and now manufactured by Boeing Defense, Space & Security. The Chinook is a Military transport helicopter, heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native Americans in the United States, Native American Chinook people of Oregon and Washington (state), Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the Radial engine, piston-engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, some Army officials consider ...

CH-53E Super Stallion
The Sikorsky CH-53E Super Stallion is a heavy lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. Developed in the 1970s, it entered service in 1981, and is planned to be in service into the 2030s. It is one of the largest military helicopters in service, and is operated from U.S. Navy ships or from land. The Navy also operates the MH-53E Sea Dragon which fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and performs heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E and enter service in the 2020s. Most of the Super Stallions in service are configured a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Parachute
A parachute is a device designed to slow an object's descent through an atmosphere by creating Drag (physics), drag or aerodynamic Lift (force), lift. It is primarily used to safely support people exiting aircraft at height, but also serves various purposes like slowing cargo, aiding in space capsule recovery, and stabilizing vehicles or objects. Modern parachutes are typically made from durable fabrics like nylon and come in various shapes, such as dome-shaped, rectangular, and inverted domes, depending on their specific function. The concept of the parachute dates back to ancient attempts at flight. In 852 AD, Armen Firman, in Córdoba, Spain, made the first recorded jump with a large cloak to slow his fall. Renaissance figures like Francesco di Giorgio Martini and Leonardo da Vinci later sketched designs resembling modern parachutes, but it wasn’t until the 18th century that the first successful jumps occurred. French Louis-Sébastien Lenormand made the first public jump i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
