List Of U.S. Army Munitions By Supply Catalog Designation
The Ammunition Identification Code (AIC) was a sub-set of the Standard Nomenclature List (SNL). The SNL was an inventory system used from 1930 to 1958 to catalog all the items the Army's Ordnance Corps issued. The AIC was used by the United States Army Ordnance Corps from January, 1942 to 1958. It listed munitions and explosives (items from SNLs P, R, S, and T), items that were considered priority issue for soldiers in combat. The markings used by the system made it easier for soldiers to quickly identify and procure the right items. It used a code that had five parts. # The first character consisted of the item's SNL Group and was represented by its letter. # The second character indicated the sub-group and was represented by its number. # The third character represented the weapon or weapons that could use it and was represented by a letter. # The fourth character represented the type and model of ammunition (i.e., Training Blank, Ball, Armor-Piercing, Incendiary, Tracer, etc.), ...

Standard Nomenclature List
This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958. The explains that the "''Index of Standard Nomenclature Lists (...) covers – by groups, and subdivisions of groups – ''all'' classes of equipment and supplies, assigned to the Ordnance Department for procurement, storage, issue, and maintenance.''" The designations in this Wikipedia list represent so-called "''major items''". For ''each'' of the ''major items'', there were separate, designated "Standard Nomenclature Lists" — extensive parts catalogs for supply and repair purposes. In essence, the index was a ''list of lists''. There could be numerous volumes, changes, and updates under each single item designation. According to the Corps' Ordnance Publications for Supply Index of Ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

37 Mm Gun M1
The 37 mm gun M1 was an anti-aircraft autocannon developed in the United States. It was used by the US Army in World War II. The gun was produced in a towed variant, or mounted along with two M2 machine guns on the M2/ M3 half-track, resulting in the T28/T28E1/M15/M15A1 series of multiple gun motor carriages. In early World War II, each Army Anti-Aircraft Artillery (AAA) Auto-Weapons battalion was authorized a total of thirty-two 37 mm guns in its four firing batteries, plus other weapons. During World War II the 37 mm gun M1 was deployed in coast defense anti- motor torpedo boat batteries (AMTB) alongside 90 mm guns, usually four 90 mm and two 37 mm guns per battery. Some AMTB batteries consisted of four 37 mm guns, but most sources have little information on these batteries. In the later part of the war the 37 mm gun was typically replaced by the 40 mm Bofors gun M1.McGovern and Smith, p. 43 Components Two gun units were coupled to the ...

M115 Howitzer
The M115 203 mm howitzer, also known as the M115 8-inch Howitzer, and originally the M1 8-inch Howitzer was a towed heavy howitzer developed and used by the United States Army during World War II, the Korean War, and the Vietnam War. History During World War I, licensed production of the British 8-inch howitzer Mark VI was undertaken by the Midvale Steel and Ordnance Company, located in the Nicetown neighborhood of Philadelphia, Pennsylvania. Both American and British-manufactured weapons were used by the American Expeditionary Force in France. In 1940, the United States still had 475 Mark VII and Mark VIII 1/2 howitzers in storage, but there are no reports of the Mark VI or other marks being used during World War II. The original design of the M1 8-inch howitzer started in 1919, and resulted in the M1920 howitzer, but the program lapsed until resurrected in 1927. The T2 and T3 howitzers were prototypes of a partner piece for a new 155 mm gun. The first publicity pho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
155 Mm Gun M1917
The Canon de 155 Grande Puissance Filloux (GPF) modèle 1917 was a WWI-era French-designed 155 mm gun used by the French Army and the United States Army during the first half of the 20th century in towed and self-propelled mountings. History The gun was designed during the First World War by Colonel Louis Filloux to meet an urgent need for modern heavy artillery and became the standard heavy field gun of the French Army from 1917 until the Second World War. It was also adopted by the United States as the M1917 and a close derivative of it was made in and used by the US as the M1918 through the Second World War. The design adopted the split trail invented by French Colonel Deport in the early 1910s (see Cannone da 75/27 modello 11), and unlike the previous pieces, which had their carriages riveted from machined and/or pressed steel parts, utilized very large steel castings. The gun was also manufactured in the United States from 1917, after the US switched to metric arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allotropes Of Phosphorus
Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and atomic phosphorus. White phosphorus White phosphorus, yellow phosphorus or simply tetraphosphorus () exists as molecules made up of four atoms in a tetrahedral structure. The tetrahedral arrangement results in ring strain and instability. The molecule is described as consisting of six single P–P bonds. Two crystalline forms are known. The α form is defined as the standard state of the element, but is actually metastable under standard conditions. It has a body-centered cubic crystal structure, and transforms reversibly into the β form at 195.2 K. The β form is believed to have a hexagonal crystal structure. White phosphorus is a translucent waxy solid that quickly becomes yellow when exposed to light. For this reason it is also called yellow phosphorus. It glows greenish in t ...

Sulfur Mustard
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
155 Mm Gun M1
The 155 mm gun M1 was a 155 millimeter caliber field gun developed and used by the United States military. Nicknamed "Long Tom" (an appellation with a long and storied history in U.S. field and naval artillery), it was produced in M1 and M2 variants, later known as the M59. Developed to replace the Canon de 155mm GPF, the gun was deployed as a heavy field weapon during World War II and the Korean War, and also classed as secondary armament for seacoast defense. The gun could fire a shell to a maximum range of , with an estimated accuracy life of 1,500 rounds. The Long Tom was also adopted by a number of other nations, including the United Kingdom, Austria, Israel, and the Netherlands. Development Before entering World War I, the United States was poorly equipped with heavy artillery. To address this problem a number of foreign heavy artillery guns were adopted, including the Canon de 155 mm GPF. After the end of the war the Westervelt Board was convened to assess the art ...

Medium Machine Gun
A medium machine gun (MMG), in modern terms, usually refers to a belt-fed machine gun firing a full-powered rifle cartridge, and is considered "medium" in weight (). Medium machine guns are light enough to be infantry-portable (as opposed to a heavy machine gun, which completely relies on mounting onto a weapons platform for operational stability and mobility), but still cumbersome enough to require a crew for optimal operational efficiency (as opposed to a light machine gun, which can be operated to full capacity by only a single gunner). History Late 19th century In the late 19th century, Gatling guns and other externally powered types, such as the Nordenfelt, were often made in different ranges of calibers, such as half-inch and one-inch. Thanks to their many barrels, overheating was not a major issue, and they were also quite heavy, being, essentially, heavy machine guns. When Hiram Maxim developed his recoil-powered machine gun that used a single barrel, the first ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M7 Grenade Launcher
The M7 grenade launcher, formally rifle grenade launcher, M7, was a 22 mm grenade, 22 mm rifle grenade launcher attachment for the M1 Garand rifle that saw widespread use throughout World War II and the Korean War. The M7 was a tube-shaped device, with one end slotting over the muzzle of the rifle and attaching to the bayonet mount, and the other end holding the grenade in place. Blank (cartridge), Blank cartridges were loaded into the rifle prior to firing. When fired, the expanding gases generated by the cartridges propelled the grenade forward with considerable force. The M7 could fire grenades up to , compared with the maximum of achieved by a hand-thrown grenade. Anti-armor (M9 rifle grenade, M9), Fragmentation (M17), and smoke grenades (M22) were available for the M7. Development When the United States entered World War II at the end of 1941, all infantry were issued with the Mk 2 grenade, Mk 2 hand grenade, fragmentation hand grenade. Owing to its hand-thrown nature, it h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1 Garand Rifle
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the U.S Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the bolt-action M1903 Springfield as the U.S.' service rifle in 1936, and was itself replaced by the selective-fire M14 rifle on March 26, 1958. Pronunciation Sources differ on the pronunciation of the M1 Garand. Some, such as General Julian Hatcher's ''The Book of the Garand'' (1948), give , identical to the pronunciation of John Garand's surname. However, a 1952 issue of ''Arme ...
