Continuous Track
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the t ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank or simply tank,Ogorkiewicz 2018 p222 is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armour allowed for the design of a tank that had the firepower of a super-heavy tank, the armour protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. The first ''designated'' MBT was the British Chieftain (tank), Chieftain tank, which during its development in the 1950s was re-designed as an MBT. Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles. Main battle tanks are a key component of modern armies.Main battle tank#House1984, House (1984), ''Toward Combined Arms Warfare: A Surve ...

Operation Defensive Shield
Operation Defensive Shield ( ) was a 2002 Israeli military operation in the Israeli-occupied West Bank during the Second Intifada. Lasting for just over a month, it was the largest combat operation in the territory since the 1967 Arab–Israeli War. The operation began with an Israeli incursion into Ramallah, where Yasser Arafat was placed under siege at his compound. This was followed by successive incursions into the six largest West Bank cities and their surrounding localities. Israel's military moved into Tulkarm and Qalqilya on April 1, into Bethlehem on April 2, and into Jenin and Nablus on April 3. From April 3 to 21, Israel enforced strict curfews on the Palestinian populace of the West Bank and restricted movements of international personnel, including prohibiting entry to humanitarian and medical personnel and human rights monitors and journalists.

Battle Of Jenin 2002
The Battle of Jenin, took place in the Jenin refugee camp in the Israeli-occupied West Bank on April 1–11, 2002. The Israeli military invaded the camp, and other areas under the administration of the Palestinian Authority, during the Second Intifada, as part of Operation Defensive Shield. Israeli forces employed infantry, commando forces, and assault helicopters. Palestinian militants had prepared for a fight, booby trapping locations throughout the camp, and after an Israeli column walked into an ambush, the army began to rely more heavily on the use of armored bulldozers. On April 11, Palestinian militants began to surrender. Israeli troops began withdrawing from the camp on April 18. Despite reports of a widespread massacre numbering hundreds of casualties by some Palestinian officials, subsequent investigations found no evidence to substantiate it, and official totals from Palestinian and Israeli sources confirmed between 52 and 54 Palestinians, including civilians, an ...

Improvised Explosive Device
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional warfare, conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs. The term "IED" was coined by the British Army during the Northern Ireland conflict to refer to booby traps made by the Provisional Irish Republican Army, IRA, and entered common use in the U.S. during the Iraq War. IEDs are generally utilized in terrorist operations or in asymmetric warfare, asymmetric unconventional warfare or urban warfare by insurgent guerrilla warfare, guerrillas or commando forces in a theater (warfare), theatre of operations. In the Iraq War (2003–2011), Iraqi insurgency (2003–2011), insurgents used IEDs extensively against U.S.-led forces, and by the end of 2007, IEDs were responsible for approximately 63% of Multi-National ...

Israeli Demolition Of Palestinian Property
Demolition of Palestinian property is a method Israel has used in the Israeli-occupied territories since they came under its control in the Six-Day War, as well as in Israel proper, to achieve various aims. Broadly speaking, demolitions can be classified as either administrative, punitive/dissuasive and as part of military operations. The Israeli Committee Against House Demolitions estimated that Israel had razed 55,048 Palestinian structures as of 2022. In the first several months of the ongoing Gaza war, Israel further demolished over 2,000 Palestinian homes in the West Bank. Furthermore, Israel has demolished homes within its borders, targeting Bedouin and Palestinian Druze communities. Israel justifies these demolitions by claiming that the houses are built without permits. Arab Israeli communities have argued that getting building permits in Israel is exceedingly difficult for Palestinian citizens. Administrative house demolitions are done to enforce building codes and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Second Intifada
The Second Intifada (; ), also known as the Al-Aqsa Intifada, was a major uprising by Palestinians against Israel and its Israeli-occupied territories, occupation from 2000. Starting as a civilian uprising in Jerusalem and October 2000 protests in Israel, Israel proper, Israeli security responded with extreme violence, killing over 100 Palestinian protesters within the first few weeks. This led to the uprising devolving into a period of heightened violence in Palestine and Israel. This violence, including shooting attacks, suicide bombings, and military operations continued until the Sharm El Sheikh Summit of 2005, Sharm el-Sheikh Summit of 2005, which ended hostilities. The general triggers for the unrest are speculated to have been centered on the failure of the 2000 Camp David Summit, which was expected to reach a final agreement on the Israeli–Palestinian peace process in July 2000. An uptick in violent incidents started in September 2000, after Israeli politician Arie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vehicle Armor
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid composit ...

Caterpillar D7
The Caterpillar D7 is a medium track-type tractor manufactured by Caterpillar Inc. and most commonly used as a bulldozer. The D7 was first manufactured in 1938. A series of improved models were later produced, including the D7C in 1955, the D7D in 1959, the D7E in 1961, the D7F in 1969 and the D7G in 1974. In 1986 the D7H was the first D7 equipped with Caterpillar’s elevated drive sprocket undercarriage. The D7R replaced the D7H in 1996, followed by the D7R Series 2. The electric drive D7E entered service in early 2009, returning to a traditional ‘flat-track’ configuration for this iteration only. The high-drive design returned in 2020 with the introduction of the D7 (forgoing a generational letter under Caterpillar’s new naming system). In March 2008, at Conexpo 2008 held every 3 years in Las Vegas, Caterpillar introduced the D7E. This D7E comes with a diesel-electric drive system powered by a 537cid C9.3 diesel engine.
