Megarangers

When the Empire took control of the universe after years of civil war, there were many who had no interest in living under Imperial rule. Smugglers, war criminals, even civilians, many weren't happy. They took to worlds outside of primary jurisdiction and lived life as criminals, smugglers, anything.

One group composed of smugglers, civilians and more ended up coming across a system on one of their jobs. The system held the Space Ranger equipment, giving them the power to become Rangers and do something about the Empire they despised. If confronted, now they could fight instead of being forced to run.

However, this was an Imperial weapon, so the Empire developed another set to counter them, and has given authorization for deadly force on sight.

So basically Firefly with suits.
