Goliath Powered Armor is the main armor worn by the Martian Marine Corps Force Recon Marines for combat scenarios. These suits are resistant to most small arms.
Goliath Mark ⅢEdit
An older generation powered, vacuum-rated armor used by the Martian Marine Corps Force Recon Marines. This armor has largely been replaced with the Mark Ⅳ.
Goliath Mark ⅣEdit
At the time of the Ganymede incident the Mark Ⅳ powered armor suit was the main suit in use by the Martian Marine Corps. Although lacking any visible differences to the previous model, the Mark Ⅳ has a completely reworked firmware incompatible with Mark Ⅲ suits.
Goliath armor utilizes an inbuilt multi-barrel gatling gun as its main armament with both armor-piercing and high-explosive rounds. Inbuilt mini-missiles have also been shown to be worn within the back of the armor and can be remotely targeted. Grenades are also used by Marines in this armor.
- In the books the Marines onboard the Donnager wore powered armor similar if not the same as the Goliath Mk Ⅲ. This was changed on the show version with the Marines wearing standard non-powered armor that appears to be standard in the Martian Congressional Republic Navy. This difference was largely due to the evolution of armor design by the art production team between season 1 and season 2 where the Donnager Marines appeared in the first year's episodes and the Scirocco Marines appeared in the second year's episodes.
- Most small arms used on ships are incapable of penetrating the armor of these suits as they are designed not to penetrate the hull of ships exposing the interiors to vacuum by gunfire. In spite of this, a skilled sharpshooter can obtain an accurate kill against this armor by targeting points in the faceplate.
- In the show, the armor is painted silver with red trim detail; however, the book armor units are painted in camouflage with Marines on Mars having red/orange paint and on Ganymede having a grey paint scheme.
