M3 Lee
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two different forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75 mm gun and coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible and serve only until replaced by the following M4 Sherman tank. The M3 was reliable, had considerable firepower, good armor, and high mobility b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M3 Submachine Gun
The M3 is an American .45 ACP, .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3.Iannamico, Frank, ''The U.S. M3-3A1 Submachine Gun'', Moose Lake Publishing, , (1999), pp. 14, 22–24, 34–39, 44–46, 54–55, 59–63, 67, 73–74 The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to mass produce and lighter, at the expense of accuracy. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser", owing to its visual similarity to the Grease gun, mechanic's tool.Ingram, Mike: ''The MP40 Submachine Gun'', p. 85. Zenith Imprint, 2001. The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944. By late 1944, the M3A1 variant was introduced, which also saw use in the Korean War and later conflicts. The M14 rifle, adopted in 1959, was intended to replace the M3A1 (as well as the M1 Garand, M1918 Brown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M3 Machine Gun
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 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. It is the primary heavy machine gun of NATO countries and has been used by many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leica M3
The Leica M3 is a 135 film, 35 mm rangefinder camera by Ernst Leitz GmbH (now Leica Camera, Leica Camera AG), introduced in 1954. It was a new starting point for Leitz, which until then had only produced screw-mount Leica cameras that were incremental improvements to its original Leica (Ur-Leica). The M3 introduced several features to the Leica, among them the combination of viewfinder and rangefinder in one bright window, like on the Contax II, a bayonet lens mount, and rapid film advance lever. It was the most successful model of the M series, with over 220,000 units sold by the time production of the M3 model ended in 1967. It was succeeded by a number of later film Leica M series, M series cameras, including the Leica M-A film camera in 2014. The earliest Leica M3 pre-model that was built, sold at auction in 2009 for €72,000. In June 2019 a pre series model from 1952/1953 was sold for €360.000 at the 34th Leitz auction in Wetzlar.

105 Mm Howitzer M3
The 105 mm Howitzer M3 was a U.S. light howitzer designed for use by airborne troops. The gun utilized the barrel of the 105 mm Howitzer M2, shortened and fitted to a slightly modified split trail carriage of the 75 mm pack howitzer. The howitzer was used by the U.S. Army during World War II. It was issued to airborne units and the cannon companies of infantry regiments. Development and production The process of building airborne forces in 1941 led to a requirement for an air-portable 105 mm howitzer. The weapon, initially designated T7, featured a barrel from the 105mm Howitzer M2, shortened by and combined with the recoil system and carriage from the 75 mm pack howitzer. A prototype reached trials at Aberdeen Proving Ground in March 1942.Zaloga - ''US Field Artillery of World War II'', p 13-14. The howitzer was designed to fire the same ammunition as the M2 howitzer, however, it was found that the shorter barrel resulted in incomplete burning of the propelling ch ...

Benelli M3 Super 90
The Benelli M3 is a dual-mode (hybrid pump-action and semi-automatic) shotgun designed and manufactured by Italian firearms manufacturer Benelli Armi SpA, and the third model of the Benelli Super 90 line of semi-automatic shotguns. The M3 holds a maximum of seven rounds and uses Benelli's proprietary inertia-driven action system first showcased in the M1. The M3 is notable for allowing the user to choose between semi-automatic or pump-action operation. Background Pump-action operation is employed when shooting less powerful shells, such as rubber bullets, that do not generate enough recoil to operate the semi-automatic mechanism. Conversely, the semi-automatic mode can be employed with more powerful shells, absorbing some of the recoil. Switching between the two modes is done by manipulating the ring located at the front of the forend grip. The Benelli M3 also features a removable stock allowing the user to choose one of two styles, the traditional shotgun stock or a stock with ...

Modula-3
Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+. It has been influential in research circles (influencing the designs of languages such as Java, C#, Python and Nim), but it has not been adopted widely in industry. It was designed by Luca Cardelli, James Donahue, Lucille Glassman, Mick Jordan (before at the Olivetti Software Technology Laboratory), Bill Kalsow and Greg Nelson at the Digital Equipment Corporation (DEC) Systems Research Center (SRC) and the Olivetti Research Center (ORC) in the late 1980s. Modula-3's main features are modularity, simplicity and safety while preserving the power of a systems-programming language. Modula-3 aimed to continue the Pascal tradition of type safety, while introducing new constructs for practical real-world programming. In particular Modula-3 added support for generic programming (similar to templates), multithreading, exception handling, garbage collection, o ...

M3 (Canadian TV Channel)
CTV Life Channel is a Canadian English language discretionary specialty channel owned by BCE Inc. through its Bell Media subsidiary. The channel primarily broadcasts factual and reality programming on lifestyle topics such as cooking, home improvement and real estate, along with scripted drama series. The channel was established in 1998 as MuchMoreMusic, a spin-off of the youth-oriented MuchMusic, by its owner CHUM Limited, the owner of Citytv, targeting an older demographic with adult contemporary and classic music videos, along with music news programs, concert specials, and pop culture programming (usually sourced from the U.S. network VH1, which shared a similar positioning). Under Bell ownership, and following the lead of its parent network, the channel adopted a general entertainment format and began to heavily downplay music programming outside non-peak hours (similar to Much at the time). On September 1, 2016, M3 was relaunched as the new version of Gusto, acquired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
