RX-121-1 Gundam TR-1 ［Hazel Custom］ Sub Arm Unit

The RX-121-1 Gundam TR-1 [Hazel Custom] w/ Sub Arm Unit is a mobile suit featured in Advance of Zeta: The Flag of Titans.

Technology & Combat Characteristics
The multi weapon latch in the center skirt armor of the RX-121-1 Gundam TR-1 [Hazel Custom] is 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, contains secondary arms folded away inside what looks at first glance like extra skirt armor. These sub arms allow the Hazel to carry a beam rifle or other weapons even when both its main arms are obstructed by the attachment of shield boosters. The sub arms can 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 add to the mobile suit's fire control means they require a high degree of pilot skill, so this system is never widely adopted.
