HGUC: #116 Gundam MSN-06S SINANJU 1/144 scale model kit.
From the Universal Century series.
 
An HGUC Sinanju! Bandai has created magic by bringing you the Sinanju, previously available only in a 1/100 scale Master Grade kit, as a 1/144 scale High Grade kit! This special HGUC has many of the same features that made the MG Version so special, such as movable thrusters on the legs and backpack, a Grenade Launcher that attaches to the Beam Rifle or shield, and Beam Axes that can be attached to the shield. Bandai has also included an extra set of hands molded in fist-clenching form.
