Ammunition is a generic term derived from the French language la munition which embraced all material used for war (from the Latin munire, to provide), but which in time came to refer specifically to gunpowder and artillery. The collective term for all types of ammunition is munitions. In the widest sense of the word it covers anything that can be used in combat that includes bombs, missiles, warheads, and mines (landmines, naval mines, and anti-personnel mines)—that munitions factories manufacture. The purpose of ammunition is predominantly to project force against a selected target. However, the nature of ammunition use also includes delivery or combat supporting munitions such as pyrotechnic or incendiary compounds. Since the design of the cartridge, the meaning has been transferred to the assembly of a projectile and its propellant in a single package.

The subject of ammunition is a complex one which covers application of fire to targets, general use of weapons by personnel, explosives and propellants, cartridge systems, high explosive projectiles (HE), warheads, shaped charge forms of attack on armour and aircraft, carrier projectiles, fuzes, mortar ammunition, small arms ammunition, grenades, mines, pyrotechnics, improved conventional munitions, and terminally guided munition.

The Black Hills (Pahá Sápa in Lakota, Moʼȯhta-voʼhonáaeva in Cheyenne) are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, USA.Harney Peak, which rises to 7,244 feet (2,208 m), is the range's highest summit. The Black Hills encompass the Black Hills National Forest and are home to the tallest peaks of continental North America east of the Rockies. The name "Black Hills" is a translation of the Lakota Pahá Sápa. The hills were so-called because of their dark appearance from a distance, as they were covered in trees.

Native Americans have a long history in the Black Hills. After conquering the Cheyenne in 1776, the Lakota took over the territory of the Black Hills, which became central to their culture. In 1868, the U.S. government signed the Fort Laramie Treaty of 1868, exempting the Black Hills from all white settlement forever. However, when European Americans discovered gold there in 1874, as a result of George Armstrong Custer's Black Hills Expedition, erstwhile miners swept into the area in a gold rush. The US government re-assigned the Lakota, against their wishes, to other reservations in western South Dakota. Unlike most of South Dakota, the Black Hills were settled by European Americans primarily from population centers to the west and south of the region, as miners flocked there from earlier gold boom locations in Colorado and Montana.
