Ontos
Ontos, officially the Rifle, Multiple 106 mm, Self-propelled, M50, was a U.S. light armored tracked anti-tank vehicle developed in the 1950s. It mounted six 106 mm manually loaded M40 recoilless rifles as its main armament, which could be fired in rapid succession against single targets to increase the probability of a kill. Although the actual caliber of the main guns was 105 mm, it was designated 106 mm to prevent confusion with the ammunition for the 105 mm M27 recoilless rifle, which the M40 replaced. It was produced in limited numbers for the U.S. Marines after the U.S. Army cancelled the project. The Marines consistently reported excellent results when they used the Ontos for direct fire support against infantry in numerous battles and operations during the Vietnam War. The American stock of Ontos was largely expended towards the end of the conflict and the Ontos was removed from service in 1969. Development The ''Ontos'' (Greek for "thing") proje ...

Battle Of Huế
The Battle of Huế (31 January 1968 – 2 March 1968), also called the Siege of Huế, was a major military engagement in the Tết Offensive launched by North Vietnam and the Việt Cộng during the Vietnam War. After initially losing control of most of Huế and its surroundings, the combined South Vietnamese and American forces gradually recaptured the city over one month of intense fighting. The battle was one of the longest and bloodiest of the war, and the battle negatively affected Opposition to United States involvement in the Vietnam War, American public perception of the war. By the beginning of the North Vietnamese Tet Offensive on 30 January 1968, which coincided with the Vietnamese Tết Lunar New Year, large conventional American forces had been committed to combat operations on Vietnamese soil for almost three years. National Route 1 (Vietnam), Highway 1, passing through the city of Huế, was an important supply line for Army of the Republic of Vietnam (ARVN) ...

M40 Recoilless Rifle
The M40 recoilless rifle is a portable, crew-served 105 mm recoilless rifle made in the United States. Intended primarily as an anti-tank weapon, it could also be employed in an antipersonnel role with the use of an antipersonnel-tracer flechette round. The bore was commonly described as being 106 mm caliber but is in fact 105 mm; the 106 mm designation was intended to prevent confusion with incompatible 105 mm ammunition from the failed M27. The air-cooled, breech-loaded, single-shot rifle fired fixed ammunition and was used primarily from a wheeled ground mount. It was designed for direct firing only, and sighting equipment for this purpose was furnished with each weapon, including an affixed spotting rifle. A limited number of M50 Ontos were built as a self-propelled light armored tracked anti-tank vehicle. They had six 106 mm M40 recoilless rifles as its main armament, which could be fired in rapid succession against a single target to guarantee ...

M56 Scorpion
The M56 "Scorpion" Self-Propelled Gun is an American unarmored, airmobile self-propelled tank destroyer, which was armed with a 90mm M54 gun with a simple blast shield, and an unprotected crew compartment. History The M56 was manufactured from 1953 to 1959 by the Cadillac Motor Car Division of General Motors for use by US airborne forces, though the vehicle was eventually used by the Spanish Navy Marines, Morocco and South Korea. With a crew of four (commander, gunner, loader and driver), the M56 weighed empty and combat-loaded. It had infrared driving lights but no NBC protection and was not amphibious. The M56 was a fully tracked vehicle with rubber-tired run-flat road wheels and front drive sprocket wheels. It was powered by a Continental A01-403-5 gasoline engine developing at 3,000 rpm, allowing a maximum road speed of and a maximum range of . Twenty-nine rounds of main gun ammunition were carried, and only the small 5 mm thick blast shield was armored. In servi ...

Tank Destroyer
A tank destroyer, tank hunter, tank killer, or self-propelled anti-tank gun is a type of armoured fighting vehicle, armed with a direct fire artillery gun or missile launcher, designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has s ...

Dominican Civil War
The Dominican Civil War (), also known as the April Revolution (), took place between April 24, 1965, and September 3, 1965, in Santo Domingo, Dominican Republic. It started when civilian and military supporters of the overthrown democratically-elected president Juan Bosch ousted the militarily-installed president Donald Reid Cabral from office. The second coup prompted General Elías Wessin y Wessin to organize elements of the military loyal to President Reid ("loyalists"), initiating an armed campaign against the "constitutionalist" rebels. In riposte, the dissidents passed out Cristóbal carbines and machine guns to several thousand civilian sympathizers and adherents. Allegations of foreign communist support for the rebels led to a United States intervention in the conflict (codenamed Operation Power Pack), which later transformed into an Organization of American States occupation of the country by the Inter-American Peace Force. Elections were held in 1966, in the after ...

Anti-tank
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such a ...
