This is a model of the standard RPA(Robot Power Armor) used by the Serian Military. Before you guys start complaining about the arms, those are proportioned intentionally big. The RPA's design is inspired largely by RIFTS RPAs developed by Triax in West Germany.

I'll have more details later, but time is short for me at the moment. Hope you all like it!

This is a standard model for a combat oriented Robot Power Armor, standing about ten feet tall. The pilot's legs fit in the cavity of the robot's thighs, over the exhaust ports--the RPA's kneecaps. There are pedals where the feet rest that control acceleration and the motion of the RPA. The remainder of the body fits in the chest cavity, with the arms fitting in special control tubes that control the movement of the arms and torso. Neural networks over the marine helmet control the motion of the RPA's main camera, fixated in the head. The arms of the RPA are long and bulky to keep attention away from the exposed arm tubes on the cockpit and to protect the chest cavity if necessary.

Despite it's heavy, unbalanced appearance, the legs are strong and will carry the pilot quickly. Their top speed measures at about 40 miles per hour and their reactor gives them enough power to keep going for over a week without needing to refuel. It is not recommended for a marine to stay tucked into the RPA's for longer than necessary, lest they begin to suffer from muscle atrophy.

A camera feed projects a wide screened view of the environment through the perspective of a ten-foot tall giant. The sensation that the pilot has become a much larger creature is not uncommon. The Graphical User Interface is a 256-bit Jadevine-coded interface which relies on voice and optical sensory interaction with an emergency touchpad for secondary control. It is a streamlined, easy-to-use operating system even for human recruits.

The armor itself is made of high-grade ceramic plating with the pilot cockpit reinforced with titanium. It is vacuum sealed, can operate in space, ground, and underwater, can withstand sustained fire from a tank. It is also modular to the desires of the user, capable of wielding a multitude of weapons, including shoulder mounted mini-missile launcher, head mounted anti-personnel machine guns, grenade launchers, auto cannons, mortars, rocket launchers, and the standard 1.12 Terawatt Plasma Rifle.

These are the bread and butter units of the Serian Empire. A single squad of marines in these RPAs could take out a 21st century fully armed battalion of Earth's best trained soldiers...they are, however, not invincible. They are prone to wear and tear and even the strong armor can be penetrated with armor piercing weapon such as a fifty caliber rifle or SABOT rounds. High Explosives can wear out the armor in the gears and joints, where the armor is slightly weaker. Menders and grunts, therefore, are still necessary to provide the RPAs with support as needed.
