Raad-2
Raad-2 (Persian:رعد-۲ 'Thunder-2') is an Iranian self-propelled howitzer. Development In early September 1997, it was reported that Iran had successfully tested a locally built rapid fire mobile field gun known as ''Raad''-2 (Thunder-2). It uses a turret that has a similar layout to the M109A1 155mm/39-cal self-propelled howitzer. The Iranian Defense Industries Organization claimed that the 155 mm HM44 howitzer manufactured by the Hadid facility of the Iranian Defense Industries Organization had a high firing rate and accuracy. The gun's range was reported as , and it also includes features such as a laser range-finder and a semi-automatic loading system. The gun looks exactly like 155mm/39-cal M185 gun from M109A1 and is fitted with a double baffle muzzle brake, fume extractor, screw breech mechanism, hydro-pneumatic recuperator and a hydraulic recoil brake. DIO says that the barrel life is around 5,000 rounds. The vehicle uses a chassis based on the T-72 The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M109 Howitzer
The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44 and M52. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. It has a crew of four: the section chief/commander, the driver, the gunner, and the ammunition handler/loader. The British Army replaced its M109s with the AS-90. Several European armed forces have or are currently replacing older M109s with the German PzH 2000. Upgrades to the M109 were introduced by the U.S. (see variants) and by Switzerland (KAWEST). With the cancellation of the U.S. Crusader, non-line-of-sight cannon and M1299 the M109A6 ("Paladin") will likely remain the principal self-propelled howitzer for the U.S. until a replacement enters service. Operational history The M109 was the medium variant of a U.S. program to adopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-72 Operators And Variants
The T-72 is a Soviet Union, Soviet-designed main battle tank that entered production in 1973. It replaced the T-54/55 series as the workhorse of Soviet tank forces (while the T-64 and T-80 served as the Soviet high-technology tanks). In front-line Russian service, T-72s are being upgraded or augmented by the T-90, itself a modernized version of the T-72B. The T-72 has been exported and produced in many countries.

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article o ...

Armoured Fighting Vehicles Of Iran
Armour (Commonwealth English) or armor (American English; see American and British English spelling differences#-our, -or, spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some combat aircraft, mostly ground attack aircraft. A second use of the term ''armour'' describes Division (military)#Armoured division, armoured forces, #Armoured fighting vehicles, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour".

Sacred describes something that is dedicated or set apart for the service or worship of a deity; is considered worthy of spiritual respect or devotion; or inspires awe or reverence among believers. The property is often ascribed to objects (a " sacred artifact" that is venerated and blessed), or places (" sacred ground"). French sociologist Émile Durkheim considered the dichotomy between the sacred and the profane to be the central characteristic of religion: "religion is a unified system of beliefs and practices relative to ''sacred things'', that is to say, things set apart and forbidden." Durkheim, Émile. 1915. ''The Elementary Forms of the Religious Life''. London: George Allen & Unwin. . In Durkheim's theory, the sacred represents the interests of the group, especially unity, which are embodied in sacred group symbols, or using team work to help get out of trouble. The profane, on the other hand, involve mundane individual concerns. Etymology The word ''sacred'' des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Recoil Mechanism
A hydraulic recoil mechanism is a way of limiting the effects of recoil and adding to the accuracy and firepower of an artillery piece. Description The idea of using a water brake to counteract the recoil of naval cannons was first suggested to the British Admiralty by Carl Wilhelm Siemens in the early 1870s, but it took about a decade for the idea to be commercialized, primarily by Josiah Vavasseur. The usual recoil system in modern quick-firing guns is the ''hydro-pneumatic recoil system''. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber. It is commonly mounted parallel to the barrel, but is shorter and smaller. The cylinder is charged with compressed air, as well as hydraulic oil; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic da ...

Laser Range-finder
A laser rangefinder, also known as a laser telemeter or laser distance meter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used instead. Laser rangefinders are sometimes classified as type of handheld scannerless lidar. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of an instrument is correlated with the rise time, divergence, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Howitzer
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-support for infantry and tank destroyers mounting an anti-t ...
