Ho Chi Minh Campaign
The 1975 spring offensive (), officially known as the general offensive and uprising of spring 1975 (), was the final North Vietnamese campaign in the Vietnam War that led to the capitulation of the Republic of Vietnam. After the initial success capturing Phước Long Province, the North Vietnamese leadership increased the scope of the People's Army of Vietnam's (PAVN) offensive and captured and held the key Central Highlands city of Buôn Ma Thuột between 10 and 18 March. These operations were intended to be preparatory to launching a general offensive in 1976. Following the attack on Buôn Ma Thuôt, the Republic of Vietnam realized they were no longer able to defend the entire country and ordered a strategic withdrawal from the Central Highlands. The retreat from the Central Highlands, however, was a debacle as civilian refugees fled under fire with soldiers, mostly along a single highway reaching from the highlands to the coast. This situation was exacerbated by con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975.

Civilian Irregular Defense Group Program
The Civilian Irregular Defense Group (CIDG, pronounced , ; ) was a military program developed by the Central Intelligence Agency (CIA) during the Vietnam War, which was intended to develop South Vietnamese irregular military units (militia) from indigenous ethnic-minority populations. The main purpose of setting up the CIDG program was to counter the growing influence of Viet Cong (VC) in the Central Highlands by training and arming the villagers for village defense. The program rapidly expanded after the US military transferred its control from CIA to MACV after two years since its inception and changed its focus from village defense to more conventional operations. From June 1967 onwards the CIDG members were made part of the Army of the Republic of Vietnam (ARVN) or other government agencies to increase Vietnamese participation. By late 1970, the remaining CIDG camps were converted to Vietnamese Rangers (ARVN Rangers) camps. The indigenous ethnic-minority people that formed t ...

A-37 Dragonfly
The Cessna A-37 Dragonfly, or Super Tweet, is a jet-powered, light attack aircraft designed and produced by the American aircraft manufacturer Cessna. It was developed during the Vietnam War in response to military interest in new counter-insurgency (COIN) aircraft to replace aging types such as the Douglas A-1 Skyraider. A formal United States Air Force (USAF) evaluation of the T-37 Tweet basic trainer for the COIN mission was conducted in late 1962, after which it was concluded that it could be modified to effectively perform the role. The attack-orientated A-37 was directly derived from the T-37, roughly doubling in both all-up weight and engine thrust to permit considerable quantities of munitions to be carried along with extended flight endurance and additional mission avionics. The prototype YAT-37D performed its maiden flight during October 1964. While test results were positive, a production contract was not immediately forthcoming until an uptick in combat intensi ...

Recoilless Gun
A Recoilless rifle ( rifled), recoilless launcher ( smoothbore), or simply recoilless gun, sometimes abbreviated to "rr" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are often ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar (weapon)
A mortar today is usually a simple, lightweight, man-portable, Muzzleloader, muzzle-loaded cannon, consisting of a Smoothbore, smooth-bore (although some models use a Rifling, rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a Sight (device), sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy Siege, siege artillery. Mortars launch explosive shell (projectile), shells (technically called Bomb, bombs) in high arching Projectile motion, ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventi ...

IV Corps (South Vietnam)
The IV Corps () was a corps of the Army of the Republic of Vietnam (ARVN), the army of the nation state of South Vietnam that existed from 1955 to 1975. It was one of four corps in the ARVN, and it oversaw the Mekong Delta region of the country. The Mekong Delta was the heartland of agricultural South Vietnam, it encompassed the fertile alluvial plains formed by the Mekong River and its main tributary, the Bassac River. With its sixteen provinces, the Delta contained about two-thirds of the nation's population and yielded the same proportion in rice production. The terrain of IV Corps differed radically from other regions. Flat and mostly uncovered, it consisted of mangrove swamps and ricefields crisscrossed by an interlocking system of canals, natural and artificial. Except for some isolated mountains to the west near the Cambodian border, few areas in the Delta had an elevation of more than above sea level. During the monsoon season, most of the swampy land north of Route QL- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
