M2 Browning
The M2 machine gun or Browning .50-caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 Springfield, .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It has been used against infantry, light armored vehicles, watercraft, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan (2001–present), War in Afghanistan. It is the primary heavy mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Bradley
The M2 Bradley, or Bradley IFV, is an American infantry fighting vehicle that is a member of the Bradley Fighting Vehicle family. It is manufactured by BAE Systems Land & Armaments (formerly United Defense) and entered service in 1981, with fielding beginning in 1983. The Bradley is designed for reconnaissance and to transport a nine-man rifle squad, providing them protection from small arms fire, while providing firepower to both suppress and eliminate most threats to friendly infantry. It is designed to be highly maneuverable and to be fast enough to keep up with heavy armor during an advance. The M2 holds a crew of three: a commander, a gunner, and a driver, and can carry six fully equipped soldiers as passengers. In the year 2000 the total cost of the program was US$5,664,100,000 for 1,602 units, giving an average unit cost of $3,166,000, equivalent to $5,841,000 in 2025. Design The Bradley IFV was developed largely in response to the amphibious Soviet BMP family of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Carbine
The M1 carbine (formally the United States carbine, caliber .30, M1) is a lightweight semi-automatic carbine chambered in the .30 carbine (7.62×33mm) cartridge that was issued to the U.S. military during World War II, the Korean War, and the Vietnam War. The M1 carbine was produced in several variants and was widely used by military, paramilitary, and police forces around the world after World War II, most notably by the armed forces of South Korea and South Vietnam. The M2 carbine is the selective-fire version of the M1 carbine, capable of firing in both semi-automatic and full-automatic. The M3 carbine was an M2 carbine with an active infrared scope system. Despite having a similar name and physical outward appearance, the M1 carbine is not a carbine version of the M1 Garand rifle. On 1 July 1925, the U.S. Army began using the current naming convention where the "M" is the designation for "Model" and the number represents the sequential development of equipment and ...

M2 Light Tank
The M2 light tank, officially Light Tank, M2, was an American light tank of the interwar period which saw limited service during World War II. The most common model, the M2A4, was equipped with one M5 gun and five .30 cal M1919 Browning machine guns. It was originally developed from the prototype T2 light tank built by the Rock Island Arsenal, which had a Vickers-type leaf spring suspension. The suspension was replaced by the superior vertical volute system in the T2E1 series of 1935. This was put into production with minor modifications as the M2A1 in 1936, with ten produced. The main pre-war version was the M2A2, with 239 produced, becoming the main tank of the United States Army during the interwar period. The Spanish Civil War showed that tanks armed only with machine guns were ineffective. This led to the M2A4 with a 37 mm gun as the main armament. A total of 375 were delivered, the last ten as late as April 1942. The tank's only combat service was with the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Half-track Car
The M2 half-track car was an armored half-track produced by the United States during World War II. Its design drew upon half-tracks imported from France in the 1930s, employing standard components supplied by U.S. truck manufacturers to speed production and reduce costs. The concept was designed, and the pilot models manufactured by the Firestone Tire and Rubber Company (before the prototype was officially labeled M2.) Production by the White Motor Company began in 1940 and was expanded to include Autocar. The M2 was initially intended for use as an artillery tractor, but also found use with reconnaissance units. International Harvester Company built the M9 half-track, a variant of their M5 half track, to fulfill the same purpose. It saw wide use in World War II, chiefly by the United States, but also by its allies. A few legacy units were used in the Nicaraguan Revolution. History The concept of a half-track vehicle had been evaluated by the US Army Ordnance Department using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Socket M2
The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors), is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939. Technical specifications AM2 processors are incompatible with 939 motherboards and vice versa, and although it has 940 pins, it is incompatible with Socket 940. Socket AM2 supports DDR2 SDRAM memory but not DDR memory, which the previous Socket 939 supported. ''AnandTech'' reported that Socket AM2 system performance was only about 7% faster than Socket 939 equivalents, with most applications about 2% faster, despite having over 30% greater memory bandwidth due to DDR2 support. The first processor cores to support socket AM2 were the single-core Orleans (Athlon 64) and Manila (Sempron), and the dual-core Windsor (Athlon 64 X2 and Athlon 64 FX). Most processors on Socket AM2 include SSE3 instructions and we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Mortar
The M2 mortar is a 60 millimeter smoothbore, muzzle-loading, high-angle-of-fire weapon used by U.S. forces in World War II, the Korean War, and the Vietnam War for light infantry support. History and description During the late 1920s, the US Army began examining mortars to act as light infantry support weapons for company level fire support, bridging the gap between medium mortars and hand grenades. In the late 1930s, the War Department eventually settled on a 60 mm design from Edgar Brandt, a French ordnance engineer.Norris, John and Calow, Robert, ''Infantry Mortars of World War II'', Osprey Publishing (2002), , , p. 15 The Ordnance Department purchased eight of the French-built weapons in 1938, standardizing them as the Mortar, 60 mm, M1. When production drawings were revised by Watervliet Arsenal to adopt standard American threads, tubes, and plates, the weapon was redesignated the Mortar, 60 mm, M2. In January 1940, the first production contract for 1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Flamethrower
The M2 flamethrower was an American, man-portable, backpack flamethrower that was used in World War II, the Korean War, and the Vietnam War. The M2 was the successor to the M1 and M1A1 flamethrowers. Although its burn time was around 7 seconds long, and the flames were effective around 20–40 meters, it was still a useful weapon. With the arrival of flamethrower tanks, the need for flamethrower-carrying infantrymen to expose themselves to enemy fire had been greatly reduced. Though some M2s were sold off, the majority were scrapped. Combat use Second World War The M2 flamethrower saw combat use in the Pacific theater, being deployed to combat strongly fortified and entrenched Japanese positions. Following the success with the M1 flamethrower, the M2 was developed and put into combat use in 1943. Towards the end of the conflict, later models of the M2 were equipped with the fuel-thickening agent known as napalm. Variants of the M2 The M2, which was the WWII model, had hexago ...

M2 Mine
The M2 is a United States bounding anti-personnel mine used during World War II. A number of variants of the mine were produced and although the mine is no longer in US service, it can be found in Cyprus, Iran, Iraq, Korea, Laos, Oman, Rwanda, Tunisia and the Western Sahara. Copies of the mine were produced by Belgium (as the PRB M966), Pakistan (P7), Portugal (M/966) and Taiwan. The mine consists of a cylindrical steel main body containing a 60 millimeter mortar shell body (originally the M49A2), linked to a tall thin fuze stand. The fuze stand held either a pin based tripwire fuze or a combination pressure tripwire fuze with a pronged pressure cap. Later fuzes were sensitive to pressure or pull and could be used with a tripwire. When the mine is triggered a black powder charge launches the mortar shell out of the main body of the mine and into the air. A pyrotechnic delay fuse triggers the mine when it has risen to between two and three meters in height. The lethal radius of t ...
