2R2M Mortar
The 2R2M (''Rifled Recoiled Mounted Mortar'') is a vehicle-mounted, rifled 120 mm heavy mortar produced by Thales of France. It is derived from the MO-120-RT towed mortar. The 2R2M is in service with 5 nations. The US Marine Corps field-tested a mortar system derived from the 2R2M in the early 2000's under the project names ''Dragon Fire'' and ''Dragon Fire II''. More than just an adaptation of the 2R2M system to the USMC's LAV-25 chassis, this project aimed for the added option to lift the entire weapon assembly, including the semi-automated loading mechanism and the computerised fire control system, out of the carrier vehicle and put it on a carriage to be towed by a tractor vehicle such as a HMMWV. The USMC eventually dropped the Dragon Fire II project and instead opted for the baseline MO-120-RT mortar, which it called the M327 mortar, towed by a M1161 Growler, for their EFSS (''Expeditionary Fire Support System'').

Freccia IFV
The Freccia ( it, Arrow) is an Italian 8x8 wheeled Infantry fighting vehicle in use with the Italian Army. The first batch of 249 vehicles were ordered to replace Cold War VCC-2 armoured personnel carriers of the Mechanized Brigade "Pinerolo" in Southern Italy. The Freccia is built by a consortium combining Iveco (hull, engine, suspension) and Oto Melara (armament). Design The Freccia is up-armoured and improved variant of the wheeled Centauro tank destroyer fitted with the Hitfist turret (an evolution of the turret used on the Dardo infantry fighting vehicle), which is armed with an Oerlikon KBA 25mm autocannon and carries 200 rounds of 25×137mm ammunition. Two 7.62mm NATO machine guns are also fitted. Additionally, a pair of Spike MR/LR anti-tank missiles can be fitted on the turret. The Hitfist turret could theoretically also fit cannons and guns of up to 60mm calibre. Four 80mm smoke grenade launchers are mounted on each side of the turret. The fire control system is ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

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'' ...

V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. In 1980, the failure of Operation Eagle Claw (during the Iran hostage crisis) underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited. The United States Department of Defense (DoD) initiated a program to develop an innovative transport aircraft with long-range, high-speed, and vertical-takeoff capabilities, and the Joint-service Vertical take-off/landing Experimental (JVX) program officially commenced in 1981. A partnership between Bell Helicopter and Boeing Helicopters was awarded a development contract in 1983 for the V-22 tiltrotor aircraft. The Bell Boeing team joint ...

CH-53 Sea Stallion
The CH-53 Sea Stallion (Sikorsky S-65) is an American family of heavy-lift transport helicopters designed and built by the American manufacturer Sikorsky Aircraft. It was originally developed in response to a request from the United States Navy's Bureau of Naval Weapons made in March 1962 for a replacement for the Sikorsky CH-37 Mojave helicopters flown by the United States Marine Corps (USMC). In July 1962, Sikorsky's proposal, which was basically a scaled-up S-61R fitted with twin General Electric T64 turboshaft engines and the dynamic system of the S-64/CH-54, was selected. On 14 October 1964, the YCH-53A performed its maiden flight; the first deliveries of production CH-53s to operational units commenced on 12 September 1966. The first combat use of the type occurred during the following year when it was deployed to the Vietnam theatre; the CH-53 quickly proved its value for moving heavy payloads, particularly in the recovery of damaged aircraft. Several variants of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Armored Vehicle
A military armored (or armoured) car is a lightweight wheeled armored fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties used to be assigned to light cavalry. Following the invention of the tank, the armored car remained popular due to its faster speed, comparatively simplified maintenance and low production cost. It also found favor with several colonial armies as a cheaper weapon for use in underdeveloped regions. During World War II, most armored cars were engineered for reconnaissance and passive observation, while others were devoted to communications tasks. Some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African Campaign. Since World War II the traditional functions of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Error Probable
In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose perimeter is expected to include the landing points of 50% of the rounds; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, 50 will fall within a circle with a radius of 100 m around their average impact point. (The distance between the target point and the average impact point is referred to as bias.) There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, and R95, which is the radius of the circle where 95% of the values would fall in. The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navigati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rock Island Arsenal
The Rock Island Arsenal comprises , located on Arsenal Island, originally known as Rock Island, on the Mississippi River between the cities of Davenport, Iowa, and Rock Island, Illinois. It lies within the state of Illinois. Rock Island was previously used as the summer camp site for Sauk Native Americans, and the dispute over tribal ownership led to the Black Hawk War of 1832, after the primary leader of the Sauk, Black Hawk. It is now home of First Army headquarters, and the US Army's Center of Excellence for Additive Manufacturing.

Fire Control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...
