Each of the Z'Gok's hands featured built-in mega particle cannons for easier and more precise aiming. Each hand also had three-claws which could be used to thrust into the Earth Federation's mobile suits (as Char Aznable demonstrated), or they could be used to smash things as well. The Z'Gok also had six 240mm missile launchers built into the head with five rounds.
240mm Missile Launcher
The MSM-07S mounts six 240mm missile launchers in the top of its head, each with five rounds for a total of thirty missiles.
Mega Particle Cannon
As with Zeon's previous amphibious mobile suits, the MSM-07S Z-Gok Commander Type is equipped with a pair of mega particle cannons powered directly from the mobile suit's Minovsky type ultracompact nuclear fusion reactor. The Z-Gok's mega particle cannons are mounted in the palm of its hands.
The MSM-07S Z'Gok Commander Type, similar to most other amphibious mobile suits, was not designed with the standard manipulators such as the ones found on a Zaku. In the Z'Gok's case, three metal claws are built into each arm surrounding the Mega Particle cannon found in the palm. The claws are designed to pierce through the armor of mobile suits, which they do quite well.
Following the production of the MSM-07 Z'Gok, a few of these units were outfitted with more powerful reactors and slightly better armor/construction materials. This made the S-Types lighter and increased their overall performance. The Zeon war ace Char Aznable, better known as the "Red Comet" to his foes, piloted a Commander Type Z'Gok in his traditional red color scheme during the assault on the Earth Federation's Jaburo General HQ on November 30, U.C. 0079.
