The UNSC uses a wide plethora of ammunition, some of which ranges for the crude to high tech. Though some were previously banned by the Geneva Convention and Hague Conventions, such rules of war have been laxed in the light of recent 'extiction events'. With the introduction of high power smokeless powder, negative spin and heavier metals for armour penetration, UNSC ammunition has higher velocities, higher accuracy, higher penetrating power and higher stopping power than before.
