M1919 Browning Machine Gun
The M1919 Browning is a .30-06 Springfield, .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial weapon, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S and many other countries. The M1919 was an air-cooled development of the standard U.S. machine gun of World War I, the John Browning, John M. Browning-designed water-cooled M1917 Browning machine gun, M1917. The emergence of general-purpose machine guns in the 1950s pushed the M1919 into secondary roles in many cases, especially after the arrival of the M60 machine gun, M60 in US Army service. The United States Navy also converted many to 7.62 mm NATO and designated them Mk 21 Mod 0; they were commonly used on riverine craft in the 1960s and 1970s in Vietnam. Many NATO countries also converted their examples to 7.62 mm caliber, and these remained in service well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MACV Compound Duster Post-Tet Feb
The U.S. Military Assistance Command, Vietnam (MACV) was a joint-service command of the United States Department of Defense, composed of forces from the United States Army, United States Navy, and United States Air Force, as well as their respective special operations forces. MACV was created on 8 February 1962, in response to the increase in United States military assistance to South Vietnam. MACV was implemented to assist and oversee the Military Assistance Advisory Group (MAAG) Vietnam while the Viet Cong insurgency was under way.

MIM-23 HAWK
The Raytheon MIM-23 HAWK ("Homing All the Way Killer") is an American medium-range surface-to-air missile. It was designed to be a much more mobile counterpart to the MIM-14 Nike Hercules, trading off range and altitude capability for a much smaller size and weight. Its low-level performance was greatly improved over Nike through the adoption of new radars and a continuous wave semi-active radar homing guidance system. It entered service with the US Army in 1959. In 1971 it underwent a major improvement program as the Improved Hawk, or I-Hawk, which made several improvements to the missile and replaced all of the radar systems with new models. Improvements continued throughout the next twenty years, adding improved electronic counter-countermeasures, ECCM, a potential home-on-jam feature, and in 1995, a new warhead that made it capable against short-range tactical ballistic missiles. ''Jane's Information Group, Jane's'' reported that the original system's single shot kill probab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a Director (military), 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 Crew-served weapon, gunner firing a weapon, but attempts to do so faster and more accurately. Naval 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 indirect fire, direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the Battle of Hampton Roads, 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 lig ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M19 Multiple Gun Motor Carriage
The M19 multiple gun motor carriage (MGMC) was a World War II United States Army self-propelled anti-aircraft weapon on the M24 light tank chassis. It was equipped with two Bofors 40 mm guns. It was produced by Cadillac and Massey Ferguson of Canada near the end of 1944. The M19 was developed from the T65 which was based on the M5 light tank chassis. With the M5 going out of production, the project adopted the M24 Chaffee light tank chassis and was designated the T65E1. It was accepted into service in May 1944 as the M19 MGMC, equipping several U.S. Army anti-aircraft units during World War II. The M19A1 was an improved variant with an auxiliary engine and spare barrels for the 40 mm Bofors guns. Although all M19s were produced during World War II, they did not reach operational capability until after the cessation of hostilities. The M19's first combat was in Korea in 1950 against North Korean forces. Specifications The M19 MGMC had similar specifications to the ...

M24 Chaffee
The M24 Chaffee (officially light tank M24) was an American light tank used during the later part of World War II; it was also used in post–World War II conflicts including the Korean War, and by the French in the Algerian War, War in Algeria and the First Indochina War. In British service it was given the service name ''Chaffee'' after the United States Army General officer, general, Adna R. Chaffee Jr., who helped develop the use of tanks in the United States Armed Forces, United States armed forces. Although the M41 Walker Bulldog was developed as a replacement, M24s were not mostly removed from U.S. and NATO armies until the 1960s and remained in service with some Third World countries. Development and production history British combat experience in the North African campaign identified several shortcomings of the M3 Stuart light tank, especially the performance of its 37 mm Gun M3, 37 mm cannon. A 75 mm gun was experimentally fitted to a howitzer motor carriage M8 & ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies.
