Shredder round

Shredder rounds are designed to splinter on impact, tearing through light armor and rending flesh. They were usually fired from Assault Rifles as a replacement for Armour Piercing Rounds. However, they do have a severe lack of penetration power and they are all but useless against Covenant personnel shields.

This type of ammunition was often used by the Spartan-II's when they ran out of AP ammunition, for example in the Lambda Serpentis System in 2535, the Spartans of Blue Team switched to using shredder rounds after exhausting all of their AP rounds when gunning down a horde of Grunts. Another example also in Fall of Reach is when Blue team was at Cote d'Azur. The Spartans were in a firefight with two hunters in a museum and when they found out that the AP rounds were not affective against the Hunter's armor, John ordered the team to switch to shredder rounds and shoot the floor beneath the Hunters.
