File No. 121 Arm-Mounted Pulse Lasers 腕部パルスレーザー

Fourth-Generation Sentinel armament. Shoots laser beams from both arms intermittently. To make the intervals between each burst shorter, it sacrifices some precision, but since it can fire many lasers in a wide arrea it is often used to keep enemy forces in check. Fourth-Generation units are the only Sentinels capable of using laser weapons, the arm-mounted pulse lasers being one of them.
