shotgun (also known as a scattergun,[1] or historically as a fowling piece) is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which usually discharges numerous small pellet-like spherical sub-projectiles called shot, or sometimes a single solid projectile called a slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available. Shotguns: Break action Lever action Pump action Semi automatic Fully automatic Shotguns come in a wide variety of calibers and gauges ranging from 5.5 mm (.22 inch) to up to 5 cm (2.0 in), though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double-barreled, or in the form of a combination gun. Like rifles, shotguns also come in a range of different action types, both single-shot and repeating. For non-repeating designs, over-and-under and side-by-side break action shotguns are by far the most common variants. Although revolving shotguns do exist, most modern repeating shotguns are either pump-action or semi-automatic, and also fully automatic, lever-action or bolt-action to a lesser extent. Preceding smoothbore firearms (such as the musket) were widely used by armies in the 18th century. The muzzleloading blunderbuss, the direct ancestor of the shotgun, was also used in similar roles from self-defense to riot control. Shotguns were often favored by cavalry troops in the early to mid-19th century because of its ease of use and generally good effectiveness on the move, as well as by coachmen for its substantial power. But by the late 19th century, these weapons became largely replaced on the battlefield by breechloading rifled firearms shooting spin-stabilized cylindro-conoidal bullets, which were far more accurate with longer effective ranges. The military value of shotguns was rediscovered in the First World War, when American forces used the pump-action Winchester Model 1897s in trench fighting to great effect. Since then, shotguns have been used in a variety of close-quarter roles in civilian, law enforcement and military applications. The smoothbore shotgun barrel generates less resistance and thus allows greater propellant loads for heavier projectiles without as much risk of overpressure or a squib load, and are also easier to clean. The shot pellets from a shotshell are propelled indirectly through a wadding inside the shell and scatter upon leaving the barrel, which is usually choked at the muzzle end to control the projectile scatter. This means each shotgun discharge will produce a cluster of impact points instead of a single point of impact like other firearms. Having multiple projectiles also means the muzzle energy is divided among the pellets, leaving each individual projectile with less penetrative kinetic energy. The lack of spin stabilization and the generally suboptimal aerodynamic shape of the shot pellets also make them less accurate and decelerate quite quickly in flight due to drag, giving shotguns short effective ranges. In a hunting context, this makes shotguns useful primarily for hunting fast-flying birds and other agile small/medium-sized game without risking overpenetration and stray shots to distant bystander and objects. However, in a military or law enforcement context, the high short-range blunt knockback force and large number of projectiles makes the shotgun useful as a door breaching tool, a crowd control or close-quarters defensive weapon. Militants or insurgents may use shotguns in asymmetric engagements, as shotguns are commonly owned civilian weapons in many countries. Shotguns are also used for target-shooting sports such as skeet, trap and sporting clays, which involve flying clay disks, known as "clay pigeons", thrown in various ways by a dedicated launching device called a "trap".
A rocket propelled grenade (RPG) is a shoulder-fired rocket weapon that launches rockets equipped with an explosive warhead. Most RPG'S 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 and they are stabilized with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPG'S are generally loaded from the front. RPG's with high-explosive anti-tank (HEAT) warheads are very effective against lightly armoured vehicles such as armoured personnel carriers (APC's) and armoured cars. However, modern, heavily-armoured vehicles, such as upgraded APC's and main battle tanks (MBT's), are generally too well-protected (with thick composite or reactive armour) to be penetrated by an RPG, unless less armoured sections of the vehicles are exploited. Various warheads are also capable of causing secondary damage to vulnerable systems (especially sights, tracks, rear and roof of turrets)and other unarmoured targets. The term "rocket propelled grenade" is from the Russian term "Ручной противотанковый гранатомет", meaning "Handheld anti-tank grenade launcher", the name given to early Russian designs
Grass is a type of plant with narrow leaves growing from the base. A common kind of grass is used to cover the ground in places such as lawns and parks. Grass is usually the color/colour ‘green’. Grasses are monocotyledon herbaceous plants. The grasses include the "grass" of the family Poaceae. This family is also called Gramineae. The family also include some of the sedges (Cyperaceae) and the rushes (Juncaceae).[1] These three families are not closely related but all of them belong to clades in the order Poales. They are similar adaptations to a common life-style. The true grasses include cereals, bamboo and the grasses of lawns (turf) and grassland. Uses for graminoids include food (as grain, sprouted grain, shoots or rhizomes), drink (beer, whisky), pasture for livestock, thatching thatch, paper, fuel, clothing, insulation, construction, sports turf, basket weaving and many others. Many grasses are short, but some grasses can grow very tall, such as Bamboo. Plants from the grass family can grow in many places and make grasslands, including areas which are very arid or cold. There are several other plants that look similar to grass and are referred to as such, but are not members of the grass family. These plants include rushes, reeds, papyrus and water chestnut. Seagrass is a monocot in the order Alismatales. Grasses are an important food for many animals, such as deer, buffalo, cattle, mice, grasshoppers, caterpillars and many other grazers. Unlike other plants, grasses grow from the bottom, so when animals eat grass they usually do not destroy the part that grows.[2] This is a part of why the plants are successful. Without grass, soil may wash away into rivers (erosion).
rifle (also known as assault rifle) is a medium sized gun with a medium barrel designed to shoot rapidly at enemy (in this case WOMEN) the bullet is a 2cm round that can be shot up to 30m while dealing critical strike when hit
