There are two primary Law Enforcement organisations on the High Frontier.
ISPF
ISPF operatives tend to favour some kind of light blue overalls/flight suit. Can also utilise a light grey over-jacket depending on the environmental situation.
Insignia tends to include a flag of the native country on the left arm with an installation badge above the ISPF logo badge on the right arm. Baseball caps are also occasionally worn. Nametapes (with the last name) are over the left breast of all uniform items.
Typical belt equipment can include a sidearm, radio, flashlight and some kind of portable computer. Additional equipment might be some kind of CSI equipment such as evidence bags, gloves, barricade tape, etc.
Federal District Marshalls
The Federal Marshals are not too dissimilar from their opposite office, but the base uniform tends to be a much darker blue and usually consists of a shirt/pants combination.
Typical equipment consists of a sidearm and shotguns are the preferred weapon (with a potential variety of load outs).
Insignia tends to be the FSA logo along with the installation on the right arm, an official badge of office on the front left breast pocket.
