Call of Duty 3Edit
The ammo box is issued to the Support and Anti-Armor classes in multiplayer. The ability is referred to as "Ammo Delivery" when selecting the kit, and simply as "Ammo" when dropping the box during gameplay.
Call of Duty: Black Ops IIIEdit
The Ammo Box is available as a power-up in the Zombies map Dead Ops Arcade 2: Cyber's Avengening. It takes the form of a box of ammo. When picked up, it will hover above the player's head until it expires. Its effect changes every time the player collects it, but it generally either extends the effect of an equipped pick up weapon (such as the Death Machine) or acts like a Skull power-up.
