Ammunition is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads).

The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds.

Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapons and by different users. There are also specific types of ammunition that are designed to have a specialized effect on a target, such as armor-piercing shells and tracer ammunition, used only in certain circumstances. Ammunition is commonly labeled or colored in a specific manner to assist in its identification and to prevent the wrong ammunition types from being used accidentally or inappropriately.

Grendel is a character in the Anglo-Saxon epic poem Beowulf (700–1000 CE). He is one of the poem's three antagonists (along with his mother and the dragon), all aligned in opposition against the protagonist Beowulf. He is referred to as both an eoten and a þyrs, types of beings from wider Germanic mythology. He is also described as a descendant of the Biblical Cain and "a creature of darkness, exiled from happiness and accursed of God, the destroyer and devourer of our human kind." He is usually depicted as a monster or a giant, although his status as a monster, giant, or other form of supernatural being is not clearly described in the poem and thus remains the subject of scholarly debate. The character of Grendel and his role in the story of Beowulf have been subject to numerous reinterpretations and re-imaginings. Grendel is feared by all in Heorot but Beowulf, who kills both him and his mother.

A rifle is a long-barreled firearm designed for accurate shooting and higher stopping power, with a barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles have been used in warfare, law enforcement, hunting and target shooting sports.

The term was originally rifled gun, with the verb rifle referring to the early modern machining process of creating grooves with cutting tools. By the 20th century, the weapon had become so common that the modern noun rifle is now often used for any log-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger.

Like all typical firearms, a rifle's projectile (bullet) is propelled by the contained deflagration of a combustible propellant compound (originally black powder and now nitrocellulose and other smokeless powders), although other propulsive means are used, such as compressed air in air rifles, which are popular for vermin control, small game hunting, competitive target shooting and casual sport shooting (plinking).

The distinct feature that separates a rifle from the earlier smoothbore long guns (e.g., arquebuses, muskets) is the rifling within its barrel. The raised areas of a barrel's rifling are called lands; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservation of angular momentum, increasing accuracy and hence effective range.
