M110 155mm Cartridge
The M110 155mm Projectile is an artillery shell used by the U.S. Army and U.S. Marine Corps. The M110 was originally designed as a chemical artillery round to deliver blister agents via howitzer as a replacement for the World War I-era 75mm chemical projectiles. The design was later repurposed as a white phosphorus smoke round for marking, signaling, and screening purposes. The white phosphorus variants of the shell also have a secondary, incendiary effect. Original design Officially designated Projectile, 155mm howitzer, M110, the original round was a 26.8-inch (68.1 cm), steel shell with a rotating band near its base and a burster rod down its center. The original shell typically contained of Sulfur mustard (H) or distilled sulfur mustard (HD), which would fill the hollow space in the shell. As early as the 1960s, a white phosphorus version was created under the same designation with of white phosphorus filler. Both versions were designed for employment by the M114 Ho ...

Artillery Shell
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shap ...

Chemical Weapon
A chemical weapon (CW) is a specialized munition that uses chemicals formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves." Chemical weapons are classified as weapons of mass destruction (WMD), though they are distinct from nuclear weapons, biological weapons, and radiological weapons. All may be used in warfare and are known by the military acronym NBC (for nuclear, biological, and chemical warfare). Weapons of mass destruction are distinct from conventional weapons, which are primarily effective due to their explosive, kinetic, or incendiary potential. Chemical weapons can be widely dispe ...

M121 155mm Projectile
The M121/A1 155mm Projectile was a chemical artillery shell designed for use by the U.S. Army. It was designed to be used with approximately of GB or VX nerve agents. History The U.S. Army standardized the M121 shell in 1954 as an artillery shell capable of delivering sarin via a 155mm howitzer.Smart, Jeffery K. Medical Aspects of Chemical and Biological Warfare'': Chapter 2 - History of Chemical and Biological Warfare: An American Perspective,PDF p. 51), ''Borden Institute'', Textbooks of Military Medicine, PDF via Maxwell-Gunter Air Force Base, accessed November 13, 2008. Shortly after the discovery of VX in 1952, the U.S. Army Chemical Corps began experimenting with employment systems for the newly discovered nerve agent. The M121A1 was standardized in 1961 as a modified version of the original projectile with the additional capability of transporting VX as well as sarin. The M121 and M121A1 have never been used in combat and remaining stockpiles are currently being dispo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M104 155mm Projectile
The M104 155 mm projectile is a chemical artillery shell designed for use by the U.S. Army. It was specifically designed to carry about of sulfur mustard (H) or (HD) blister agent (distilled mustard). As early as the 1960s, the shell was also filled with white phosphorus to be used for obscuration and signaling. History and design Following World War I, militaries around the world began working to standardize calibers of ammunition within their countries. In the United States, the military began focusing on replacing the European-made 75 mm artillery shells with 105 mm and 155 mm shells. The M104 (along with the M110, which it shares many design elements with) was designed as a 155 mm artillery shell for use in the M114 howitzer. It is a steel shell with a rotating band near the base, and a burster well that goes down the center of the shell. Filler of either sulfur mustard or white phosphorus is placed in the empty space and a fuze is fixed to the top before firing. Var ...

Smoke Screen
A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships. Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship). Whereas smoke screens were originally used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and they are also available for vehicles in a super-dense form used to block laser beams of enemy target designators or range finders. Technology Smoke grenades These are canister-type grenades used as a ground-to-ground or ground-to-air signalling device. The body consists of a steel sheet metal cylinder with a few emission holes on the top and/or bottom to allow smoke release when the smoke composition inside the grenade is ignited ...

Smoke Signal
The smoke signal is one of the oldest forms of long-distance communication. It is a form of visual communication used over a long distance. In general smoke signals are used to transmit news, signal danger, or to gather people to a common area. History and usage In ancient China, soldiers along the Great Wall sent smoke signals on its beacon towers to warn one another of enemy invasion. The colour of the smoke communicated the size of the invading party. By placing the beacon towers at regular intervals, and situating a soldier in each tower, messages could be transmitted over the entire 7,300 kilometres of the Wall. Smoke signals also warned the inner castles of the invasion, allowing them to coordinate a defense and garrison supporting troops. In ancient Sri Lanka, soldiers stationed on the mountain peaks would alert each other of impending enemy attack (from English people, Dutch people or Portuguese people) by signaling from peak to peak. In this way, they were able to tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Weapons Convention
The Chemical Weapons Convention (CWC), officially the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, is an arms control treaty administered by the Organisation for the Prohibition of Chemical Weapons (OPCW), an intergovernmental organization based in The Hague, The Netherlands. The treaty entered into force on 29 April 1997, and prohibits the large-scale use, development, production, stockpiling and transfer of chemical weapons and their precursors, except for very limited purposes (research, medical, pharmaceutical or protective). The main obligation of member states under the convention is to effect this prohibition, as well as the destruction of all current chemical weapons. All destruction activities must take place under OPCW verification. As of August 2022, 193 states have become parties to the CWC and accept its obligations. Israel has signed but not ratified the agreement, while three other U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Incendiary Ammunition
Incendiary ammunition is a type of ammunition that contains a chemical that, upon hitting a hard obstacle, has the characteristic of causing fire/setting flammable materials in the vincinity of the impact on fire. World War I The first time incendiary ammunition was widely used was in World War I, more specifically in 1916. At the time, phosphorus was the primary ingredient in the incendiary charge and ignited upon firing, leaving a trail of blue smoke. These early forms were also known as "smoke tracers" because of this. Though deadly, the effective range of these bullets was only 350 yards (320 m), as the phosphorus charge burned quickly. Incendiary bullets called "Buckingham" ammunition were supplied to early British night fighters for use against military zeppelins threatening the British Isles. The flammable hydrogen gas of the zeppelins made incendiary bullets much more deadly than standard ones which would pass through the outer skin without igniting the gas. Similar ...
