Ammunition

Ammo is shorthand for “ammunition,” which means bullets, gunpowder, and other combat supplies. A war movie might include a scene of soldiers running out of ammunition. Ammunition generally refers to collecting the actual munitions or exploding substances and projectiles put in guns, cannons, and other weapons.

The purpose of ammo is to project a force against a selected target to have an effect (usually, but not always, lethal). The most iconic example of a shot is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package.
