1975 Spring Offensive
The 1975 spring offensive ( vi, chiến dịch mùa Xuân 1975), officially known as the general offensive and uprising of spring 1975 ( vi, Tổng tiến công và nổi dậy mùa Xuân 1975) was the final North Vietnamese campaign in the Vietnam War that led to the capitulation of 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 h ...

Vietnam War
The Vietnam War (also known by other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was supported by the United States and other anti-communist allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh took control of North Vietnam, and the U.S. assumed financial and military support for the South Vietnames ...

Dư Quốc Đống
Lieutenant General Dư Quốc Đống (1932 – 22 April 2008) was an officer of the Army of the Republic of Vietnam (ARVN). Career In 1965 Đống served as commander of the Airborne which together with the Marines formed the South Vietnamese general reserve and had a significant political role to play in Saigon. Đống allied with General Nguyễn Văn Thiệu, while General Lê Nguyên Khang commanding the Marines was an ally of Đống's rival Air Vice Marshal Nguyễn Cao Kỳ. The general reserve troops represented the muscle of the Saigon-based Directory members and balanced power between the rival officer cliques. In 1966 US advisers reported that Đống was highly resistant to American advice. Because of his close relationship with Thiệu, Joint General Staff chief General Cao Văn Viên, his nominal superior, was reluctant to discipline Đống and instead passed on American misgivings to Thiệu. Thiệu valued the support of Đống's Saigon-based paratrooper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A-37 Dragonfly
The Cessna A-37 Dragonfly, or Super Tweet, is an American light attack aircraft developed from the T-37 Tweet basic trainer in the 1960s and 1970s by Cessna of Wichita, Kansas. The A-37 was introduced during the Vietnam War and remained in peacetime service afterward. Design and development The growing American military involvement in Vietnam in the early 1960s led to strong interest in counter-insurgency (COIN) aircraft. In late 1962, the U.S. Air Force's Special Air Warfare Center at Eglin Air Force Base's Hurlburt Field in Florida evaluated two T-37Cs for the role. The Air Force found the T-37 promising, but wanted an improved version of the aircraft that could carry a much larger payload, and had much greater endurance and better short-field performance. This meant a heavier aircraft with more powerful engines. In 1963, the Air Force awarded a contract to Cessna for two prototype YAT-37D aircraft: T-37s with modifications that included: *Stronger wings. *Three stores ...

Recoilless Gun
A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "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 called recoilless rifles. Though sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar (weapon)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used 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. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Center Of Military History

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-4, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tây Nguyên
Central Highlands ( vi, Cao nguyên Trung phần), Western Highlands ( vi, Tây Nguyên) or Midland Highlands ( vi, Cao nguyên Trung bộ) is one of the regions of Vietnam. It contains the provinces of Đắk Lắk, Đắk Nông, Gia Lai, Kon Tum, and Lâm Đồng. Provinces History The native inhabitants of the Central Highlands (Montagnards, Mountain peoples) are various peoples that mainly belonged to the two major Austronesian (Highland Chamic) and Austroasiatic ( Bahnaric) ethnolinguistic families. According to Peng et al. (2010) & Liu et al. (2020), Austronesian Chamic groups were well known of being seafarers with the original homeland of Taiwan, might have migrated to present-day Central Vietnam by sea from Maritime Southeast Asia around ~ 2,500 kya, while were making contact/or possibly absorbed the previously earlier Austroasiatic inhabitants (research shows shared high frequencies of AA-associated ancestry among Vietnam's Austronesian Chamic highlanders than ...

Bình Trị Thiên
Bình Trị Thiên (1975–1990) was a former administrative grouping of three provinces in Vietnam: Quảng Bình, Quảng Trị and Thừa Thiên. The grouping did not work well and was reversed in 1992.
