Zulfiqar (tank)
Zulfiqar (ذوالفقار) is an Iranian main battle tank, conceived by Brigadier General Mir-Younes Masoumzadeh, deputy ground force commander for research and self-sufficiency of the armed forces. It is named after Zulfiqar, the legendary sword of Ali the fourth Caliph and the first Shiite Imam. It's also known as Zolfaqar. The test prototypes of the tank were evaluated in 1993. Six semi-industrial prototypes of the tank were produced and tested in 1997. Design specifications Features The tank has a distinctive box-shaped, steel-welded turret of local design. The Zulfiqar is believed to be developed from major components of the Soviet T-72 and American M48 and M60 tanks. The suspension is modelled on the M48 /M60 Patton tanks supplied to Iran by the U.S. The SPAT 1200 transmission also seems to be a local development of that of the M-60. Zulfiqar-1's combat weight has been reported to be 36 tonnes with a 780 hp diesel engine; giving the tank a 21.7 hp per ton rat ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through 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 armored fighting vehicles. Main battle tanks are a key component of modern armies.#House1984, House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in inf ...

EE-T1 Osório
The Engesa EE-T1 ''Osório'' was a Brazilian main battle tank prototype developed by Engesa. The tank was intended to be sold first to Arab and other Third World countries, jump-starting production — and enabling the Brazilian Army to later place its own orders without having to fund development costs. Development of the tank was initially privately funded by Engesa, but cashflow issues eventually led to the Brazilian government extending a loan to assist the program. Two prototypes of the tank were built, but the EE-T1 was never adopted for service. Development The EE-T1 was envisioned by Engesa as a cost-effective tank made using domestically produced components. The tank was intended for the foreign market. Development started in 1982 and the first prototype was completed in 1985. The initial development of the tank was expensive and caused a cashflow crisis at Engesa, prompting the Brazilian National Development Bank to extend a $65 million loan to finance the program in 1 ...

Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less armament and are not designed to provide direct fire support in battle. Infantry units which travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units which use APCs and infantry units which use IFVs, with the latter being known as armoured infantry in such militaries.

Boragh
Boragh or Boraq ( fa, نفربر براق) is an Iranian-made armoured personnel carrier. Boragh is believed to be a reverse engineered and upgraded model of the Chinese Type 86 (BMP-1). The upgrades include a reduction in weight, a higher road speed, and stronger armor. The vehicle is fully amphibious and is fitted with an NBC protection system and infra-red night vision equipment. It was reported in May 2002 that three additional variants are produced by the Vehicle and Equipment Group (VEIG) of the Iranian Defence Industries Organisation (DIO). These are a 120 mm mortar carrier, an ammunition resupply vehicle, and an armoured personnel carrier (APC) fitted with improved armaments. Description Boragh is a tracked APC. Rubber elements on the track are added to prevent damage on paved surfaces. It has a crew of three (driver, commander and gunner). It can transport up to 8 infantry soldiers. Boragh's main armament consists of the DShK 1938/46 12.7 mm heavy machine g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hashemi Rafsanjani
Akbar Hashemi Rafsanjani ( fa, اکبر هاشمی رفسنجانی, Akbar Hāshemī Rafsanjānī, born Akbar Hashemi Bahramani, 25 August 1934 – 8 January 2017) was an Iranian peoples, Iranian politician, writer, and one of the founding fathers of the Government of the Islamic Republic of Iran, Islamic Republic who was the fourth president of Iran from 1989 to 1997. He was the head of the Assembly of Experts from 2007 until 2011 when he decided not to nominate himself for the post. He was also the chairman of the Expediency Discernment Council. During his 40-year tenure, Rafsanjani amassed a large amount of power serving as the speaker of parliament, Commander-in-Chief during the Iran–Iraq War, President, and chose Ali Khamenei as the supreme leader of Iran. His powerful role and control over Iranian politics earned him the name "Akbar Shah". Rafsanjani became president of Iran after winning the 1989 Iranian presidential election, 1989 election. He served another term by w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant General
Lieutenant general (Lt Gen, LTG and similar) is a three-star military rank (NATO code OF-8) used in many countries. The rank traces its origins to the Middle Ages, where the title of lieutenant general was held by the second-in-command on the battlefield, who was normally subordinate to a captain general. In modern armies, lieutenant general normally ranks immediately below general and above major general; it is equivalent to the navy rank of vice admiral, and in air forces with a separate rank structure, it is equivalent to air marshal. A lieutenant general commands an army corps, made up of typically three army divisions, and consisting of around 60 000 to 70 000 soldiers (U.S.). The seeming incongruity that a lieutenant general outranks a major general (whereas a major outranks a lieutenant) is due to the derivation of major general from sergeant major general, which was a rank subordinate to lieutenant general (as a lieutenant outranks a sergeant major). In contrast, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reactive Armor
Reactive armour is a type of vehicle armour that reacts in some way to the impact of a weapon to reduce the damage done to the vehicle being protected. It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators. The most common type is ''explosive reactive armour'' (ERA), but variants include ''self-limiting explosive reactive armour'' (SLERA), ''non-energetic reactive armour'' (NERA), ''non-explosive reactive armour'' (NxRA), and electric armour. NERA and NxRA modules can withstand multiple hits, unlike ERA and SLERA. A second hit in exactly the same location may potentially penetrate any of those, as the armour in that spot is compromised. Reactive armour is intended to counteract anti-tank munitions that work by piercing the armour and then either kill the crew inside, disable vital mechanical systems, or create spalling that disables the crew — or all three. Reactive armour can be defeated with multiple hits in the same pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-72Z
The Type 72Z tank (also known as the T-72Z and the Safir-74, and the Al-Zubair I in Sudan) is a highly modernized version of the Type 59 and T-54/T-55 tanks, with upgrades carried out by the Iranian Defense Industries Organization. The tank is not to be confused with an Iraqi modernization also known as ''T-72Z'', said to carry a 125 mm gun. History The Type 72Z was first announced by the Islamic Revolutionary Guard Corps in 1996. The upgrades to the Type 59 and T-54/T-55 tanks were carried out by the Vehicle Industries Group of the Defence Industries Organization, in order to extend the service life of tanks already in use with the Iranian army. Upgrades The 100mm gun of the T-55/Type 59 was replaced with an Iranian-produced derivative of the 105mm M68 gun, capable of firing 9M117 Bastion anti-tank guided missiles as well as NATO standard ammunition. The Slovenian Fotona Electronic Fire Control System (EFCS-3-55) was added, with automatic and manual gun stabilizers, a laser ...

High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, improvin ...
