The multi-weapon latch in the center skirt armor of the RX-121-1 Gundam TR-1 [Hazel Custom] was designed to serve as a multipurpose joint for various option parts used by the Hazel. This sub-arm unit, one of the devices intended to connect to the multi weapon latch, contained secondary arms folded away inside what looked at first glance like extra skirt armor. These sub-arms allowed the Hazel to carry a beam rifle or other weapons even when both its main arms were obstructed by the attachment of shield boosters. The sub-arms could also be used to wield secondary weapons like beam sabers, or to replace energy packs when both main arms are holding weapons. However, the complexity they added to the mobile suit’s fire control meant they required a high degree of pilot skill, so this system was never widely adopted.
