Technology is fairly advanced on the story this model is based on. Most powered systems are contained on the "skinsuit" - it's made of several layers of active smart materials. For example, the inner layer sustains (and repairs when needed) the body of the person wearing it, the muscle layer enhances speed and strength, the armor layer protects and repairs the suit automatically, the camouflage layer can change it's color to blend to the environment or even turn completely reflective to repel laser weapons.
Heavier systems, such as the field manipulators, sensors, anti-gravity, navigation, etc. are contained on the "bulges" at the arms, legs and backpack (the backpack also carries five small "remotes"). Extra armor is placed over such places.
The standard main weapon, a field-generated laser, is detachable and can be replaced by several other specialty weapons, or a second weapon can be attached to the other arm if needed. The armor plates morph as needed to accomodate the weapons.
