15 Cm SFH 18
The 15 cm schwere Feldhaubitze 18 or sFH 18 (German: "heavy field howitzer, model 18"), nicknamed ''Immergrün'' ("Evergreen"), was the basic German division-level heavy howitzer of 149mm during the Second World War, serving alongside the smaller but more numerous 10.5 cm leFH 18. Its mobility and firing range and the effectiveness of its 44 kilogram shell made it the most important weapon of all German infantry divisions. A total of 6,756 examples were produced. It replaced the earlier, First World War-era design of the 15 cm sFH 13, which was judged by the Krupp-Rheinmetall designer team of the sFH 18 as completely inadequate. The sFH 18 was twice as heavy as its predecessor, had a muzzle velocity increase of forty percent, a maximum firing range 4.5 kilometers greater, and a new split-trail gun carriage that increased the firing traverse twelvefold. The secret development from 1926–1930 allowed German industry to deliver a trouble-free design at the beginning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CFB Borden
Canadian Forces Base Borden (also CFB Borden, French: Base des Forces canadiennes Borden or BFC Borden), formerly RCAF Station Borden, is a large Canadian Forces base located in Ontario. The historic birthplace of the Royal Canadian Air Force, CFB Borden is home to the largest training wing in the Canadian Armed Forces. The base is run by Canadian Forces Support Training Group (CFSTG) and reports to the Canadian Defence Academy (CDA) in Kingston. History At the height of the First World War, the Borden Military Camp opened at a location on a glacial moraine west of Barrie in 1916 to train units for the Canadian Expeditionary Force. It was named for Sir Frederick William Borden, former Minister of Militia. In May 1916, the Barrie and Collingwood companies of the 157th Battalion (Simcoe Foresters), CEF (perpetuated today by The Grey and Simcoe Foresters), under the command of Lieutenant-Colonel D.H. MacLaren, began construction of the camp. Camp Borden was selected in 1917 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives * Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a ...

Corps
Corps (; plural ''corps'' ; from French , from the Latin "body") is a term used for several different kinds of organization. A military innovation by Napoleon I, the formation was first named as such in 1805. The size of a corps varies greatly, but from two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense. Within military terminology a corps may be: *an operational formation, sometimes known as a field corps, which consists of two or more divisions, such as the , later known as ("First Corps") of Napoleon I's ); *an administrative corps (or mustering) – that is a specialized branch of a military service (such as an artillery corps, a medical corps, or a force of military police) or; *in some cases, a distinct service within a national military (such as the United States Marine Corps). These usages often overlap. Corps may also be a generic term for a non-military organization, such as the US Peace Corps an ...

15 cm Kanone 18
The 15 cm Kanone 18 (15 cm K 18) was a German heavy gun used in the Second World War. Design and history In 1933 Rheinmetall began development of a new artillery piece to fulfill a German Army requirement for a replacement of the aged 15 cm Kanone 16, with the first production units received in 1938. There was not much of an improvement over the older gun as it weighed two tons more than the K 16, but only had more range. The army was happy with the range, but not with the carriage. There was a special transport carriage for just the gun when traveling long distances. Putting it on its turntable took even more time to assemble. The rate of fire was at best two rounds per minute.Bishop, Chris. The encyclopedia of weapons of world War II. Sterling Publishing Company, Inc., 2002, p.133 Around a hundred were built between 1939 and 1943. It was not popular in service as it was regarded as too much gun for too little shell. This caused its production to be term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hummel (artillery)
''Hummel'' (German: "bumblebee") was a self-propelled gun based on the ''Geschützwagen'' III/IV chassis and armed with a 15 cm howitzer. It was used by the German ''Wehrmacht'' during the Second World War from early 1943 until the end of the war. Its ordnance inventory designation was Sd.Kfz 165. The full name was ''Panzerfeldhaubitze 18M auf Geschützwagen III/IV (Sf) Hummel, Sd.Kfz. 165''. On February 27, 1944, Hitler ordered the name ''Hummel'' to be dropped as it was deemed inappropriate for a fighting vehicle. Development The ''Hummel'' was designed in 1942 after the need for mobile artillery support for tank forces had been demonstrated during the invasion of the USSR. The self-propelled artillery already in service with the Wehrmacht had proven of limited value. The first option considered was mounting a 10.5 cm leFH 18 howitzer on a Panzer III chassis, rejected in favour of the same gun on a Panzer IV chassis. One prototype was built. This design was rejected i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Assisted Projectile
A rocket-assisted projectile (RAP) is a cannon, howitzer, mortar, or recoilless rifle round incorporating a rocket motor for independent propulsion. This gives the projectile greater speed and range than a non-assisted ballistic shell, which is propelled only by the gun's exploding charge. Some forms of rocket-assisted projectiles can be outfitted with a laser-guide for greater accuracy. The German Sturmtiger (1944) used a 380 mm Rocket Propelled Round as its main projectile. These rounds were high explosive shells or shaped charges with a maximum range of 6,000 m. The gun first accelerated the projectile to 45 m/s (150 ft/s), the 40 kg (88 lb) rocket charge then boosted this to about 250 m/s (820 ft/s). Also the German Krupp K5 railway gun of World War 2 used rocket assisted projectiles in the later stages of the war, although it also used conventional artillery projectiles. The North Korean M-1978 / M1989 (KOKSAN) 170mm self-propelled gun can use rocket assisted proje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Re-armament
German rearmament (''Aufrüstung'', ) was a policy and practice of rearmament carried out in Germany during the interwar period (1918–1939), in violation of the Treaty of Versailles which required German disarmament after WWI to prevent Germany from starting another war. It began on a small, secret, and informal basis shortly after the treaty was signed, but it was openly and massively expanded after the Nazi Party came to power in 1933. Despite its scale, German re-armament remained a largely covert operation, carried out using front organizations such as glider clubs for training pilots and sporting clubs, and Nazi SA militia groups for teaching infantry combat techniques. Front companies like MEFO were set up to finance the rearmament by placing massive orders with Krupp, Siemens, Gutehofnungshütte, and Rheinmetall for weapons forbidden by the Treaty of Versailles. Carl von Ossietzky exposed the reality of the German rearmament in 1931 and his disclosures won him ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilometer
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre, n ...

Muzzle Velocity
Muzzle velocity is the speed of a projectile ( bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the sho ...

15 cm SFH 13
The 15 cm schwere Feldhaubitze 13 (15 cm sFH 13), was a heavy field howitzer used by Germany in World War I and the beginning of World War II. History The gun was a development of the previous standard howitzer, the 15 cm sFH 02. Improvements included a longer barrel resulting in better range and a gun shield to protect the crew. Variants were: the original "kurz" (L/14 – 14 calibre short barrel version), the ''lg. sFH13'' with a longer barrel; with minor modifications to simplify wartime manufacture of the lg. sFH weapons. Initially there were serious issues of weak recoil spring mechanisms that would break, and gun barrel explosions. The problems were solved with the upgrades. A sub variant of the sFH 13 was the ''lg. 15 cm sFH 13/02'' which combined the long barrel with the carriage of the earlier sFH 02 when those guns became obsolete. The sFH 13/02 gun shield wasn't hinged at the top and it only used a hydro-spring recoil system. Approximately 1,000 conv ...

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infantry
Infantry is a military specialization which engages in ground combat on foot. Infantry generally consists of light infantry, mountain infantry, motorized infantry & mechanized infantry, airborne infantry, air assault infantry, and marine infantry. Although disused in modern times, heavy infantry also commonly made up the bulk of many historic armies. Infantry, cavalry, and artillery have traditionally made up the core of the combat arms professions of various armies, with the infantry almost always comprising the largest portion of these forces. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French ''infanterie'', from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' īnfāns'' (without speech, newborn, foolish), from which English also gets '' infant''. The individual-soldier term ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
