Rocket artilleryRocket artillery is artillery that uses rocket explosives as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon). Fire arrows were also used in multiple launch systems and transported via carts. The first true rocket artillery was developed in India by the Kingdom of Mysore. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War.
RocketA rocket (from ) is a vehicle that uses jet propulsion to accelerate without using the 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.
Multiple rocket launcherA multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple launchers which are fixed to a single platform, and shoots its rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads.
Cluster munitionA cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines. Because cluster bombs release many small bomblets over a wide area, they pose risks to civilians both during attacks and afterwards.
Mareșal (tank destroyer)The Mareșal (meaning "marshal"), also known as the M-tank, was a Romanian-produced light tank destroyer from World War II. Romania was a member of the Axis powers and created the vehicle in response to the Soviet T-34 and KV-1 tanks. It is credited with having inspired the German Hetzer's design, according to multiple German military staff. A total of 1,000 vehicles were planned for production, which was to make the Mareșal the backbone of the Romanian armored forces, making it the country's most numerous armored fighting vehicle by far.
Internal TroopsInternal troops, sometimes alternatively translated as interior troops, interior ministry forces (etc.), are military or paramilitary, gendarmerie-like law enforcement services, which are found mostly in states of the former Soviet Union, primarily Russia. Internal troops are subordinated to the interior minister (and interior ministries) of their respective countries. Perhaps the most prominent example, since the Soviet era have been the Russian Внутренние войска Министерства внутренних дел (ВВ) Vnutrenniye Voiska (VV) Ministerstva Vnutrennikh Del, or "Internal Troops of the Ministry for Internal Affairs" (MVD) (until 2016).
