Granatwerfer 34
The 8 cm Granatwerfer 34 (8 cm GrW 34) was the standard German infantry Mortar (weapon), mortar throughout World War II. It was noted for its accuracy and rapid rate of fire. History The weapon was of conventional design and broke down into three loads (smooth bore barrel, bipod, baseplate) for transport. Attached to the bipod were a traversing handwheel and a cross-leveling handwheel below the elevating mechanism. A panoramic sight was mounted on the traversing mechanism yoke for fine adjustments. A line on the tube could be used for rough laying. The 8 cm GrW 34/1 was an adaptation for use in self-propelled mountings. A lightened version with a shorter barrel was put into production as the kz 8 cm GrW 42, kurzer 8 cm Granatwerfer 42. The mortar employed conventional 8 cm 3.5 kg shells (high explosive or smoke) with percussion fuzes. The range could be extended by fitting up to three additional powder charges between the shell tailfins. A total of 74 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festung Hohensalzburg
Hohensalzburg Fortress (german: Festung Hohensalzburg, lit=High Salzburg Fortress) is a large medieval fortress in the city of Salzburg, Austria. It sits atop the Festungsberg at an altitude of 506 m. It was erected at the behest of the Prince-Archbishops of Salzburg. The fortress is long and wide making it one of the largest medieval castles in Europe. History Early history Construction of the fortress began in 1077 under Archbishop Gebhard von Helfenstein. The original design was a basic bailey with a wooden wall. In the Holy Roman Empire, the archbishops of Salzburg were already powerful political figures and they expanded the fortress to protect their interests. Helfenstein's conflict with Emperor Henry IV during the Investiture Controversy influenced the expansion of the fortress, with the Archbishop taking the side of Pope Gregory VII and the German anti-king Rudolf of Rheinfelden. The fortress was gradually expanded during the following centuries. The ring walls and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adamsite
Adamsite or DM is an organic compound; technically, an arsenical diphenylaminechlorarsine, that can be used as a riot control agent. DM belongs to the group of chemical warfare agents known as vomiting agents or sneeze gases. First synthesized in Germany by Heinrich Otto Wieland in 1915, it was independently developed by the US chemist Roger Adams (for whom it is named) at the University of Illinois in 1918. Composition DM is an odourless crystalline compound with a very low vapour pressure. The colour of the crystals ranges from bright yellow to dark green depending on the purity. It is readily soluble in some organic solvents (e.g., acetone, dichloromethane), but nearly insoluble in water. In vaporous form it appears as a canary yellow smoke. Effects Adamsite is usually dispersed as an aerosol, making the upper respiratory tract the primary site of action. Although the effects are similar to those caused by typical riot control agents (e.g. CS), they are slower in onset but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ordnance ML 3 Inch Mortar
The Ordnance ML 3-inch mortar was the United Kingdom's standard mortar used by the British Army from the early 1930s to the late 1960s, superseding the Stokes mortar. Initially handicapped by its short range compared to similar Second World War mortars, improvements of the propellant charges enabled it to be used with great satisfaction by various armies of the British Empire and of the Commonwealth. Design The ML 3-inch mortar is a conventional Stokes-type mortar that is muzzle-loaded and drop-fired. It also reuses many of the Brandt mortar features. History Based on their experience in the First World War, the British infantry sought some sort of artillery for close support. The initial plan was for special batteries of artillery, but the cost was prohibitive and the mortar was accepted instead. The Mark II mortar (Mark I was the Stokes) was adopted by the British Army in the early 1930s; and this was the standard British mortar when the Second World War broke out i ...

List Of Infantry Mortars
The list of infantry mortars catalogues weapons which are issued to infantry units to provide close range, rapid response, indirect fire capability of an infantry unit in tactical combat. In this sense the mortar has been called "infantryman's artillery", and represents a flexible logistic solution to satisfying unexpected need for delivery of firepower, particularly for the light infantry.p.34, Ryan In general infantry mortars are defined by what a team of infantrymen, sometimes known as mortarmen, can transport unaided by significant vehicle support. Because of this intrinsic restriction mandated by weight, mortars are only considered "infantry" to a calibre of 120mm. These larger weapons usually require wheeled assemblies to allow their towing either by hand or by light tactical vehicles.

Phenacyl Chloride
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone. It is a useful building block in organic chemistry. Apart from that, it has been historically used as a riot control agent, where it is designated CN. It should not be confused with cyanide, another agent used in chemical warfare, which has the chemical structure CN−. Preparation Phenacyl chloride is readily available and was first prepared by chlorination of acetophenone vapour. It may also be synthesized by the Friedel-Crafts acylation of benzene using chloroacetyl chloride, with an aluminium chloride catalyst: Riot control agent It was investigated, but not used, during the First and Second World Wars. Because of its significantly greater toxicity, it has largely been supplanted by CS gas. Even though CN is still supplied to paramilitary and police forces in a small pressurized aerosol known as “ Mace” or tear gas, its use is falling as pepper spray both works and disperses mor ...

Sulfur Trioxide
Sulfur trioxide (alternative spelling sulphur trioxide, also known as ''nisso sulfan'') is the chemical compound with the formula SO3. It has been described as "unquestionably the most important economically" sulfur oxide. It is prepared on an industrial scale as a precursor to sulfuric acid. Sulfur trioxide exists in several forms - gaseous monomer, crystalline trimer, and solid polymer. Sulfur trioxide is a solid at just below room temperature with a relatively narrow liquid range. Gaseous SO3 is the primary precursor to acid rain. Molecular structure and bonding Monomer The molecule SO3 is trigonal planar. As predicted by VSEPR theory, its structure belongs to the D3h point group. The sulfur atom has an oxidation state of +6 and may be assigned a formal charge value as low as 0 (if all three sulfur-oxygen bonds are assumed to be double bonds) or as high as +2 (if the Octet Rule is assumed). When the formal charge is non-zero, the S-O bonding is assumed to be delocalized. In a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation. ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kz 8 Cm GrW 42
The kurzer 8 cm Granatwerfer 42 (kz 8 cm GrW 42) was a mortar used by Germany during World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposin .... It was developed as a lightened version of the standard German 8 cm GrW 34 medium mortar with a shorter barrel for use by paratroopers, but replaced the ineffective 5 cm leGrW 36 as that weapon's shortcomings became apparent. The kz 8 cm GrW 42 fired a bomb over 3 and a half times heavier twice as far as the smaller mortar, but was less than twice as heavy. It broke down into the standard three loads for transport. Some weapons were provided with a lanyard-operated loading/firing mechanism for remote-controlled use. It was generally known as the "Stummelwerfer" or "Stump-Thrower".
