Lunge Mine
The Shitotsubakurai ( ja, 刺突爆雷) lunge mine was a suicidal anti-tank weapon developed and used by the Empire of Japan during the Second World War. It used a HEAT type charge. This weapon was used by the CQC units of the Imperial Japanese Army. The weapon itself was a conical hollow charge anti-tank mine, placed inside a metallic container and attached to the end of a wooden stick. The weapon was officially adopted by the Japanese Army in 1945; in that year it caused its first victims in the Pacific Theater, where it commonly saw action against American armour. Later that year, some Japanese Imperial Army manuals of the weapon were discovered by US troops. Design The weapon itself was a conical hollow charge attached to one end of the weapon, which was a wooden stick used to hold the weapon during its transport and use. The mine had three equally spaced legs facing forward around the conical explosive base of the weapon. The detonator of the weapon was situated at the en ...

Suicide Attack
A suicide attack is any violent Strike (attack), attack, usually entailing the attacker detonating an explosive, where the attacker has suicide, accepted their own death as a direct result of the attacking method used. Suicide attacks have occurred throughout history, often as part of a military campaign (as with the Japanese ''kamikaze'' pilots of 1944–1945 during World War II), and more recently as part of terrorism, terrorist campaigns (such as the September 11 attacks in 2001). While few, if any, successful suicide attacks took place anywhere in the world from 1945 until 1980, between 1981 and September 2015 a total of 4,814 suicide attacks occurred in over 40 countries, killing over 45,000 people. During this time the global rate of such attacks grew from an average of three a year in the 1980s to about one a month in the 1990s to almost one a week from 2001 to 2003 to approximately one a day from 2003 to 2015. Suicide attacks tend to be more deadly and destructive t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close Quarters Combat
Close-quarters combat (CQC) or close-quarters battle (CQB) is a tactical situation that involves a physical fight with firearms involved between multiple combatants at short range. It can occur between military units, police/corrections officers and criminal elements, and in other similar situations. In warfare, it usually consists of units or teams of varying size engaging the target or attacking personnel with personal weapons within a distance of up to 100 meters (110 yards), from proximity hand-to-hand combat to close-quarter target negotiation with usually automatic weapons. In the typical close combat scenario, the attackers try a very fast, violent takeover of a vehicle or structure controlled by the defenders, who usually have no easy method to withdraw. Because attacking and defending personnel, hostages/civilians, and friendly personnel can be closely intermingled, close-quarters combat demands a rapid assault and a precise implementation of lethal force.

Japanese Inventions
This is a list of Japanese inventions and discoveries. The Japanese have made contributions across a number of scientific and technological domains. In particular, the country has played a crucial role in the digital revolution since the 20th century, with many modern revolutionary and widespread technologies in fields such as electronics and robotics introduced by Japanese inventors and entrepreneurs. Arts ;Comic book :Adam L. Kern has suggested that '' kibyoshi'', picture books from the late 18th century, may have been the world's first comic books. These graphical narratives share with modern manga humorous, satirical, and romantic themes. Some works were mass-produced as serials using woodblock printing. ; Folding hand fan :In ancient Japan, the first hand fans were oval and rigid fans, influenced greatly by Chinese fans. The earliest visual depiction of fans in Japan dates back to the 6th century AD, with burial tomb paintings showed drawings of fans. The folding fan was in ...

Anti-tank Mines
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II Infantry Weapons Of Japan
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Hanoi (1946)
On December 19, 1946, Viet Minh soldiers detonated explosives in Hanoi, and the ensuing battle, known as the Battle of Hanoi marked the opening salvo of the First Indochina War. History On September 14, 1946, France and the DRV had signed a '' modus vivendi'', promising reciprocal rights and negotiations to end armed hostilities. The French did not follow through with any political concessions. In November 1946, local disputes led to colonialist massacres at Haiphong, "Langson" (Lạng Sơn) and "Tourane" ( Da Nang). Then, France landed reinforcements at Da Nang in violation of an accord signed on March 6, 1946. Viet Minh set off explosives, at 20:03 in the evening of December 19, 1946, after smuggling them past French Army guards into the city's power plant. The explosion plunged Hanoi into darkness, and throughout the city the Viet-Minh began attacking French military positions and French homes. About 600 French civilians were abducted during this time.

Battle Of Leyte
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish. The word "battle" can also be used infrequently to refer to an entire operational campaign, although this usage greatly diverges from its conventional or customary meaning. Generally, the word "battle" is used for such campaigns if referring to a protracted combat encounter in which either one or both of the combatants had the same methods, resources, and strategic objectives throughout the encounter. Some prominent examples of this would be the Battle of the Atlantic, Battle of Britain, and Battle of Stalingrad, all in World War II. Wars and military campaigns are guided by military strategy, wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyte
Leyte ( ) is an island in the Visayas group of islands in the Philippines. It is eighth-largest and sixth-most populous island in the Philippines, with a total population of 2,626,970 as of 2020 census. Since the accessibility of land has been depleted, Leyte has provided countless number of migrants to Mindanao. Most inhabitants are farmers. Fishing is a supplementary activity. Rice and corn (maize) are the main food crops; cash crops include coconuts, abaca, tobacco, bananas, and sugarcane. There are some manganese deposits, and sandstone and limestone are quarried in the northwest. Politically, the island is divided into two provinces: (Northern) Leyte and Southern Leyte. Territorially, Southern Leyte includes the island of Panaon to its south. To the north of Leyte is the island province of Biliran, a former sub-province of Leyte. The major cities of Leyte are Tacloban, on the eastern shore at the northwest corner of Leyte Gulf, and Ormoc, on the west coast. Leyte to ...

Rolled Homogeneous Armour
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protectiv ...

Asiatic-Pacific Theater
The Asiatic-Pacific Theater was the theater of operations of U.S. forces during World War II in the Pacific War during 1941–1945. From mid-1942 until the end of the war in 1945, two U.S. operational commands were in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area, were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz. Because of the complementary roles of the United States Army and the United States Navy in conducting war, the Pacific Theater had no single Allied or U.S. commander (comparable to General of the Army Dwight D. Eisenhower in the European Theater of Operations). No actual comma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollow Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significa ...
