Ammunition is the special type of item that powers firearms. It is shown in a yellow-bordered box in the inventory management menu. Both firearm cartridges and crossbow bolts are listed on the Ammunition category.

Ammunition comes in several different calibers, from the small and modest .22 LR to the large .50 BMG. Though it is not displayed in the game, certain types of ammunition are used only on certain types of firearms (e.g. shotgun shells are only used on shotguns) while others are used in at least two types of weapons (e.g. 7.62x51mm rounds are used on both Rifles and Assault rifles)  Every firearm in the game requires ammunition from a specific caliber in the inventory of the user, or else it won't be used.

Some ammunition (usually by highest caliber) is more effective in PvP battles than other types of ammunition. A more effective ammunition is more likely to injure an enemy squad than other types of ammunition

Ammo can be obtained by scavenging in the map. Some calibers are rarer than others. (Ordered by PvP effectiveness)
