Combat Enhancement System

The Combat Enhancement System is a UNSC military program that provides infantry weapons with increased combat efficiency. Most standard-issue weapons are equipped with CES rails, allowing them to use many attachments, such as sights, aiming lasers, or flashlights. All UNSC attachment series are part of the Combat Enhancement System.
