Technology & Combat Characteristics
The Zaku II Gunner was a specialized version of the MS-06F Zaku II designed for long-range bombardment missions, as such, was extensively modified to carry the YMS-16M Xamel's large 680mm artillery cannon (nicknamed "Specter's Bullet" when attached to the Zaku II Gunner). The Gunner type uses the base frame of the F Type, rather than a J Type, because it was meant to be used on the lunar surface. To offset the powerful recoil produced by the Specter's Bullet when firing, large treads were fitted to the knee of the Gunner type which would be in a kneeling position when readying to fire the cannon. The Specter's Bullet was fitted with its own support base, and the Gunner type steadied the front end of the cannon to ensure accurate firing. The Gunner type was also equipped with a large head-mounted camera unit that supports ultra long-range targeting.
History
Designed to work in tandem with the MS-06F-2 Zaku II (Rangefinder), these two specialized Zaku II units were escorted in a operation by a MS-14JG Gelgoog Jäger where the Gunner type was used to bombard lunar cities.
