The Pinnacle, Battle Of Okinawa
The Pinnacle was the name given to a spire, atop a ridge of coral approximately southwest of Arakachi, Okinawa. Heavily fortified by the 62nd Division (Imperial Japanese Army), 62nd Division, this outpost to Japan's main defenses at Shuri, Okinawa#Under Imperial Japan, Shuri held up the U.S. 7th Infantry Division (United States), 7th Infantry Division on 5–6 April 1945 with accurate and well-concealed machine gun, mortar and artillery fire. The Pinnacle as a defensive position Lieutenant Tanigawa had built his defenses around eight light and two heavy machine guns sited at the base of the hill. In trenches and pits riflemen well-supplied with grenades covered the Field of fire (weaponry), dead spaces in front of the machine guns. The defenses were connected by the usual tunnels and trenches, affording underground mobility. On the top of the ridge were four Knee mortar, 50 mm mortars, and on the reverse slope to the south were three more. Artillery check points had been estab ...

Barbed Wire
Roll of modern agricultural barbed wire Barbed wire, also known as barb wire or bob wire (in the Southern and Southwestern United States), is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences, and it is also used as a security measure atop walls surrounding property. As a wire obstacle, it is a major feature of the fortifications in trench warfare. A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person. The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor. Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention in 1874 after he made his o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Mortar Battalion
Chemical mortar battalions were United States Army non-divisional units that were attached to infantry divisions during World War II. They were armed with 4.2-inch (107 mm) chemical mortars. For this reason they were also called the "Four-deucers". In 1943, General Mark Clark's Fifth Army established a policy that no infantry division would be committed to combat without a chemical mortar battalion attached. As a result, when infantry units were rotated out of combat, the mortar battalions often stayed in the line and were attached to fresh units. Chemical mortars were in such high demand that often the companies of a battalion would be split up and assigned to different divisions. On the first day that General George S. Patton's Third Army became operational, in the summer of 1944, he issued a standing order to his staff that no infantry division would be committed to combat without a chemical mortar battalion attached, and no infantry regiment would be committed without a morta ...

M2 4
M, or m, is the thirteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of several western European languages and others worldwide. Its name in English is ''em'' (pronounced ), plural ''ems''. History The letter M is derived from the Phoenician Mem via the Greek Mu (Μ, μ). Semitic Mem is most likely derived from a " Proto-Sinaitic" (Bronze Age) adoption of the "water" ideogram in Egyptian writing. The Egyptian sign had the acrophonic value , from the Egyptian word for "water", ''nt''; the adoption as the Semitic letter for was presumably also on acrophonic grounds, from the Semitic word for "water", '' *mā(y)-''. Use in writing systems English In English, represents the voiced bilabial nasal . The Oxford English Dictionary (first edition) says that is sometimes a vowel, such as in words like ''spasm'' and in the suffix ''-ism''. In modern terminology, this is described as a syllabic consonant (IPA: ). M is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bazooka
The Bazooka () is a Man-portable anti-tank systems, man-portable recoilless Anti-tank warfare, anti-tank rocket launcher weapon, widely deployed by the United States Army, especially during World War II. Also referred to as the "stovepipe", the innovative Bazooka was among the first generation of rocket-propelled grenade, rocket-propelled anti-tank weapons used in infantry combat. Featuring a solid-propellant rocket for propulsion, it allowed for high-explosive anti-tank (HEAT) shaped charge warheads to be delivered against Vehicle armour, armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or land mine, mine. The universally applied nickname arose from the weapon's M1 variant's vague resemblance to the musical instrument called a ''Bazooka (instrument), bazooka'' invented and popularized by 1930s American comedian Bob Burns (humorist), Bob Burns. During World War II, the Nazi Germany, German armed forces captured severa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two classes of weapons generally defined as HMGs: * The historical definition refers to machine guns, typically chambered in standard full-power cartridges, that are identified as being "heavy" due to their weight and cumbersomeness, which prevents infantrymen from transporting them on foot. Examples include the Maxim machine gun and M1917 Browning machine gun. * The modern definition refers to "heavy caliber" machine guns, pioneered by the German Empire's MG 18 TuF which was a Maxim derivative chambered in 13.2×92mmSR fielded near the end of World War I. They are designed to provide increased effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti Tank Gun
Anti-tank warfare refers to the military strategies, tactics, and weapon systems designed to counter and destroy enemy armored vehicles, particularly tanks. It originated during World War I following the first deployment of tanks in 1916, and has since become a fundamental component of land warfare doctrine. Over time, anti-tank warfare has evolved to include a wide range of systems, from handheld infantry weapons and anti-tank guns to guided missiles and air-delivered munitions. Anti-tank warfare evolved rapidly during World War II, leading to infantry-portable weapons. Through the Cold War of 1947–1991, the United States, anti-tank weapons have also been upgraded in number and performance. Since the end of the Cold War in 1992, new threats to tanks and other armored vehicles have included remotely detonated improvised explosive devices (IEDs). During the Russian invasion of Ukraine, drones and loitering munitions have attacked and destroyed tanks. Tank threat Ant ...

Stuart Light Tank
The M3 Stuart/light tank M3, was a US light tank of World War II, first entered service in the British Army in early 1941 and saw action in the North African campaign in July 1941. Later an improved version of the tank entered service as the M5 in 1942 to be supplied to British and other allied Commonwealth of Nations, Commonwealth forces under lend-lease prior to the entry of the United States into the war. The British service name "Stuart" came from the U.S. Civil War Confederate States of America, Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 light tank. Unofficially, they were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "light tank M3" and "light tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M101 Howitzer
The M101A1 (previously designated Howitzer M2A2 on Carriage M2A2) howitzer is an artillery piece developed and used by the United States. It was the standard U.S. light field howitzer in World War II and saw action in both the European and Pacific theaters and during the Korean War. Entering production in 1941, it quickly gained a reputation for accuracy and a powerful punch. The M101A1 fires 105 mm high explosive (HE) semi-fixed ammunition and has a range of or 7 miles, making it suitable for supporting infantry. History Development and designation After World War I, the U.S. Army Ordnance Department studied various captured German 105 mm-caliber howitzers and developed the 105 mm Howitzer M1920 by using the Carriage M1920. A box trail carriage design (the M1925E carriage) and two other split trail designs (the T1 and T2) were also developed, but the original split trail design was found superior after testing. After being selected, the piece was standardized i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar Fire
A mortar today is usually a simple, lightweight, man-portable, muzzle-loaded cannon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy siege artillery. Mortars launch explosive shells (technically called bombs) in high arching ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satchel Charges
A satchel charge is a demolition device, primarily intended for combat, whose primary components are a charge of dynamite or a more potent explosive such as C-4 plastic explosive, a carrying device functionally similar to a satchel or messenger bag, and a triggering mechanism; the term covers both improvised and formally designed devices. In World War II, combat engineers used satchel charges to demolish heavy stationary targets such as rails, obstacles, blockhouses, bunkers, caves, and bridges. The World War II–era United States Army M37 Demolition Kit contained eight blocks of high explosive, with two priming assemblies, in a canvas bag with a shoulder strap. Part or all of this charge could be placed against a structure or slung into an opening. It was usually detonated with a pull igniter. When used as an anti-tank weapon, charges were sufficient to severely damage the tracks. charges were enough to destroy medium tanks. Later in the Vietnam War, Vietcong and North Vie ...

Platoon
A platoon is a Military organization, military unit typically composed of two to four squads, Section (military unit), sections, or patrols. Platoon organization varies depending on the country and the Military branch, branch, but a platoon can be composed of 20–50 troops, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a Officer (armed forces), commissioned officer. The platoon leader is usually a junior officer—a Second lieutenant, second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Rifle platoons normally consist of a small platoon headquarters and three or four sections (Commonwealth) or squads (United States). In some armies, platoon is used throughout the branches of the army. In a few armies, such as the French Army, a platoon is specifically a cavalry unit, and the infantry use "section" as the equivalent unit. A unit consisting of several platoon ...
