The Ammunition Package is a deployable package that resupplies ammunition to nearby allies, It's deployed from the Engineer's Class Ability. The Ammunition Package is a vital tool in any assault, allowing players to resupply their ammunition even when in hostile territory. It's not noted in game, but it appears that the last rank of certification allows an engineer to place one extra ammunition pack at the same time. Ammo packs can be destroyed by weapons fire and EMP grenades.
