M30 Cargo Carrier
The 155 mm Gun Motor Carriage M12 was a U.S. self-propelled gun developed during the Second World War. It mounted a 155 mm gun derived from the French Canon de 155mm GPF field gun. Development The idea for the M12 was first proposed in 1941 and the pilot - T6 GMC - built and tested in early 1942. The Army Ground Forces initially rejected the design as unnecessary, but after the Artillery Board supported the Ordnance Department in asking for 50 units, 100 were authorized and built by March 1943. These vehicles were at first used for training. Description The M12 was built on the chassis of the M3 Grant tank. The engine was moved forward to the center of the vehicle to allow room for the gun mount, and most vehicles used later M4-style bogies with trailing return rollers. The armored compartment at the front was occupied by the driver and commander. The gun crew were located in an open-topped area at the back of the vehicle. It mounted a 155 mm gun M1917, M1917 ...

Self-propelled Gun
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns (tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

M40 Gun Motor Carriage
The 155 mm Gun Motor Carriage M40 was an American self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and with HVSS (Horizontal Volute Spring Suspension), which was introduced at the end of the Second World War. Description Equipped with a 155 mm M2 gun, it was designed to replace the earlier M12 Gun Motor Carriage. Its prototype designation was the T38, but this was changed to the M40 in March 1945. A single pilot vehicle was used in the European Theatre in 1945 by the 991st Field Artillery Battalion, along with a related 8 inch Howitzer Motor Carriage T89, (later re-designated the M43 Howitzer Motor Carriage) which was sometimes also equipped with a 155 mm barrel.Hunnicutt - ''Sherman: A History of the American Medium Tank'', p 353-355, 570. A total of 311 out of a planned 600 were completed by the Pressed Steel Car Company before the end of the war, 24 of which were later converted into M43s. Fr ...

Year 155 ( CLV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Rufinus (or, less frequently, year 908 ''Ab urbe condita''). The denomination 155 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Births * Cao Cao, Chinese statesman and warlord (d. 220) * Dio Cassius, Roman historian (d. c. 235) * Tertullian, Roman Christian theologian (d. c. 240) * Sun Jian, Chinese general and warlord (d. 191) Deaths * Pius I, Roman bishop * Polycarp, bishop of Smyrna (b.

Cold War Armored Fighting Vehicles Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

World War II Armored Fighting Vehicles Of The United States
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In '' scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

G-numbers
This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, — ''one'' of the alpha-numeric "Standard Nomenclature Lists" (SNL) that were part of the overall List of the United States Army weapons by supply catalog designation, a Supply Catalog that was used by the United States Army Ordnance Department / Ordnance Corps as part of the Ordnance Provision System, from about the mid-1920s to about 1958. In this, the ''Group G'' series numbers were designated to represent "Tank / Automotive materiel" – the various military vehicles and directly related materiel. These designations represent vehicles, modules, parts, and catalogs for supply and repair purposes. There can be numerous volumes, changes, and updates under each designation. The Group G list ''itself'' is also included, being numbered G-1. Generally, the G-series codes tended to group together "families" of vehicles that were similar in terms of their engine, trans ...
