RPG-16
The RPG-16 is a handheld anti-tank grenade launcher for anti-tank warfare. It was developed in 1968 and adopted by the Soviet Army in 1970 for special operation teams and the Soviet airborne troops ( VDV). These were deployed during the Soviet–Afghan War (1979–1989) and saw service during several battles in that conflict. Combat history The RPG-16 was widely used during Soviet campaign in Afghanistan, mostly against hardened fire positions and buildings from stand-off ranges. When it was first introduced it was considered superior to the RPG-7, but the RPG-7's ability to accommodate oversized rockets gave it growth potential the RPG-16's undercaliber projectile couldn't compete with. Beginning in the 1980s, it was replaced by the older RPG-7D equipped with newer and more powerful rockets. Low-rate production was maintained by Russia until the 1990s, when it was removed from service after about 120,000 units being produced. The RPG-16 was not widely exported. In 2023, Russian ...

Rocket-propelled Grenade
A rocket-propelled grenade (RPG), also known colloquially as a rocket launcher, is a Shoulder-fired missile, shoulder-fired anti-tank weapon that launches rockets equipped with a Shaped charge, shaped-charge explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target, stabilized in flight with fins. Some types of RPG are reloadable with new anti-tank grenades, while others are single-use. RPGs are generally Muzzleloader, loaded from the front. RPGs with high-explosive anti-tank (HEAT) warheads are very effective against lightly armored vehicles such as armored personnel carriers (APCs) and armored car (military), armored cars. However, modern, heavily-armored vehicles, such as upgraded APCs and main battle tanks, are generally too well-protected (with thick composite armor, composite or reactive armor) to be penetrated by an RPG, unless ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Shaped-charge
A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped 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 depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym ''HEAT'' (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature—however the process creates significant heat and often has a significant secondary incendiary ef ...

RPG-7
The RPG-7 is a portable, reusable, unguided, shoulder-launched, anti-tank, rocket launcher. The RPG-7 and its predecessor, the RPG-2, were designed by the Soviet Union, and are now manufactured by the Russian company Bazalt. The weapon has the GRAU index (Russian armed forces index) 6G3. The ruggedness, simplicity, low cost, and effectiveness of the RPG-7 has made it the most widely used anti-armor weapon in the world. Currently around 40 countries use the weapon; it is manufactured in several variants by nine countries. It is popular with irregular and guerrilla forces. Widely produced, the most commonly seen major variations are the RPG-7D (десантник – ''desantnik'' – paratrooper) model, which can be broken into two parts for easier carrying; and the lighter Chinese Type 69 RPG. DIO of Iran manufactures RPG-7s with olive green handguards, H&K style pistol grips, and a commando variant. The RPG-7 was first delivered to the Soviet Army in 1961 and deployed ...

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 protective ...

Optical Sight
A sight or sighting device is any device used to assist in precise visual alignment (i.e. ''aiming'') of weapons, surveying instruments, aircraft equipment, optical illumination equipment or larger optical instruments with the intended target. Sights can be a simple set or system of physical markers that serve as visual references for directly aligning the user's line of sight with the target (such as iron sights on firearms), or optical instruments that provide an optically enhanced—often magnified—target image aligned in the same focus with an aiming point (e.g. telescopic, reflector and holographic sights). There are also sights that actively project an illuminated point of aim (a.k.a. "hot spot") onto the target itself so it can be observed by anyone with a direct view, such as laser sights and infrared illuminators on some night vision devices, as well as augmented or even virtual reality-enabled digital cameras ("smart scopes") with software algorithms that produ ...

Airdrop
An airdrop is a type of airlift in which items including weapons, equipment, humanitarian aid or leaflets are delivered by military or civilian aircraft without their landing. Developed during World War II to resupply otherwise inaccessible troops, themselves often airborne forces, airdrops can also refer to the airborne assault itself. History Early airdrops were conducted by dropping or pushing padded bundles from aircraft. Later, small crates fitted with parachutes were pushed out of aircraft side cargo doors. Later, cargo aircraft were designed with rear access ramps, lowerable in flight, that allowed large platforms to be rolled out the back. As aircraft grew larger, the U.S. Air Force and Army developed ''low-level extraction'', allowing vehicles like light tanks, armored personnel carriers and other large supplies to be delivered. Propaganda leaflets are another commonly airdropped item. Airdrops evolved to include massive bombs as payload. The 15,000-pound (6,800 ...

Rocket
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoilless Rifle
A Recoilless rifle (rifled), recoilless launcher (smoothbore), or simply recoilless gun, sometimes abbreviated to "rr" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifling, rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HEAT
In thermodynamics, heat is energy in transfer between a thermodynamic system and its surroundings by such mechanisms as thermal conduction, electromagnetic radiation, and friction, which are microscopic in nature, involving sub-atomic, atomic, or molecular particles, or small surface irregularities, as distinct from the macroscopic modes of energy transfer, which are thermodynamic work and transfer of matter. For a closed system (transfer of matter excluded), the heat involved in a process is the difference in internal energy between the final and initial states of a system, after subtracting the work done in the process. For a closed system, this is the formulation of the first law of thermodynamics. Calorimetry is measurement of quantity of energy transferred as heat by its effect on the states of interacting bodies, for example, by the amount of ice melted or by change in temperature of a body. In the International System of Units (SI), the unit of measurement for he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
