Bandolier

Bandolier
The Bandolier perk is offered in the perk 1 slot. It doubles ur starting ammunition, which just happens to be the max amount of ammo the wepons can hold. This perk works well with weapons were ammo goes fast, such as the M16, or most SMG's for example. It's also useful for spots in levels where it is hard to collect ammunition from fallen friends or enemies.

Although weapons like the M14, Shotguns and LMG's dont really need this, since u probably won't be running out of ammo if u use it wisely.
