HG 1/144 Brave [Commander Test Type]

The Brave is the successor to the AEU-09 AEU Enact and SVMS-01 Union Flag series. Developed by ESF engineers that were once part of the AEU and Union, it is built with the latest in ESF-developed GN-Tech, and has aesthetics similar to that of its predecessors. The Brave is a pre-mass production model, still in beta phase and its design and technology are based on the GNX-U02X Masurao. The Brave is developed for use in an emergency deployment mobile suit squadron. This squadron would need to be deployed and enter combat zones in a short amount of time. In addition to its high mobility and the flight mode's long distance travel capability, the Brave also has overwhelming firepower.
