M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .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 current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, 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 ... [...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, which was formerly United Defense. The Bradley is designed for reconnaissance and to transport a squad of infantry, providing them protection from small arms fire, while also 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, as well as six fully equipped soldiers as passengers. In the year 2000 the total cost of the program was $5,664,100,000 for 1,602 units, giving an average unit cost of $3,166,000, or $5,500,000 per in 2022. Design The Bradley IFV was developed largely in response to the amphibious Soviet BMP family of infantry fighting vehicles, and to serve as both an armored p ...

M2 Carbine
The M1 carbine (formally the United States Carbine, Caliber .30, M1) is a lightweight semi-automatic carbine that was a standard firearm for 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 paramilitary and police forces around the world, and also became a popular civilian firearm after World War II. 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 July 1, 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 weapons. Therefore, the "M1 carbine" was the first carbine developed under thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Ball
The .30-06 Springfield cartridge (pronounced "thirty-aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental riml ...

M2 Half-track Car
The M2 half-track car is 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. History The concept of a half-track vehicle had been evaluated by the US Army Ordnance Department using Citroën-Kégresse vehicles. The Cavalry branch of the US Army found that their wheeled armored scout cars had trouble in wet terrain due to th ... [...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 wer ... [...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. Description The U.S. M2 60 mm mortar was licensed from French Brandt company to supplement 81 mm M1 Mortar to provide a lighter-weight alternative to company-level fire support.Norris, John and Calow, Robert, ''Infantry Mortars of World War II'', Osprey Publishing (2002), , , p. 15 The M2 attempted to bridge the gap between the 81 mm mortar and the hand grenade. Normally employed by the weapons platoon of a U.S. infantry company, the M2 is of the usual mortar pattern of the day. It consists of a smoothbore metal tube on a rectangular baseplate, supported by a simple bipod with the elevation and traverse mechanisms. The firing pin was fixed in the base cap of the tube, and the bomb was fired automatically when it dropped down the barrel. Though classed as a light morta ...

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 hexagon ...

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 ...

M2 Hyde
The Hyde-Inland M2 was a United States submachine gun design submitted for trials at Aberdeen Proving Ground in February 1941. Work was undertaken by General Motors Inland Manufacturing Division to develop workable prototypes of George Hyde's design patented in 1935 (). The model first submitted for trials in April 1942 was designated the ''Hyde-Inland 1''. Trials revealed the design was superior to the M1 submachine gun in mud and dirt tests, and its accuracy in full-automatic firing was better than any other submachine gun tested at the time. An improved ''Hyde-Inland 2'' was designated U.S. Submachine gun, Caliber .45, M2 as a substitute standard for the M1 Thompson in April 1942. As Inland's manufacturing capacity became focused on M1 carbine production, the US Army contracted M2 production to Marlin Firearms in July 1942. Marlin began production in May 1943. Marlin's production failed to match the trials prototype performance; and Marlin's original contract for 164,450 M2s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
