Three categories of Small Caliber Ammunition are currently in use. War Reserve Ammunition is ammunition with overmatch capability that supports individual and crew-served weapons during combat operations. Training Standard Ammunition is dual-purpose, and can be used to support both training and operational requirements. Training Unique Ammunition is designed specifically for use in training and is not for combat use, i.e., blank, dummy-inert, Close Combat Man-Marking Kit and short-range training ammunition.


Standard ammunition provides the warfighter with the necessary lethality needed to defeat the enemy.
