Codex
''The design of this weapon is conventional in nature, though it has been refined to perform at the limit of its ballistic capabilities. The UAC Fragmentation Grenade uses a Comp-D explosive package encased in a steel alloy shell, and has an effective fatality radius of about 5 meters. Improvements on the antiquated M67 grenade include a more reliable chemical fuse mechanism, interior machining of the casing to provide more efficient projectile dispersion and a trigger switch safety clip to prevent unwanted activation. The newer Comp-D explosive also ensures the radial pressure wave has no "drop spots" - ensuring full damage potential within the fatality zone.'' - Decoded Entry 001.
