Here is the Warlord-M1. It's the first suit that Vigil will be using.

There are braces built into the knee and elbows. Basically, when Connor runs, jumps, kicks, climbs, or punches the braces have a circular rotor on them that 'augment' the process. So if he punches, extending his arm, the motion will cause those rotors to spin, and it's sort of like being spring-loaded (except it's not spring loaded) and they propel his arm forward at a much quicker, much stronger way, effectively giving him 'enhanced strength'. This is the same with his legs and whatnot: enhancing the movement of his knees to make him run faster and jump higher. It is NOT superstrength; it may allow him to run slightly faster than Usain Bolt, or punch through a brick wall, or flip a car over; he can't punch through a steel war, he can't lift a car, and he would NOT be able to keep up with people like the Flash. You'll see it in action soon enough.

Overtime Miranda will recreate the suit into the M2, the M3, and so on.
