The military police is the only protection for Paradigm City. They provide both a defense against foreign aggression (be it a Megadeus or the Union) and provide civil defense against criminals. There are no law enforcement officials in Paradigm City outside of the military police. The military police is owned by, receives full funding from, and is under the full supervision of, the Paradigm Corporation. They are supposed to follow the orders of the Paradigm Corporation, even if those orders conflict with the general safety and welfare of the populace.
At times, as seen in the Land Buyout Riots in “Bring Back My Ghost”, they have forcibly removed people from their homes in order to make room for expansion of the domes and other Paradigm Corporation projects, resulting in mass riots amongst the residents outside the domes.
The officer seen most is Major Dan Dastun, later promoted to Colonel. Roger Smith was once a member of the military police, ranked Lieutenant and partner to Dastun, until he decided to leave the force. Though it is never stated specifically why Roger left, it is indicated that he grew increasingly disdained with Paradigm’s control over the public’s safety, and thought he could do more good in the private sector. The Military Police is torn apart by a crisis of loyalty near the end of the series, with Dastun and a large portion of the force going rogue in an attempt to support Roger and his Megadeus against an insane Alex Rosewater.
Their ranking system is similar to the police, army, and marines. The mentioned ranks are Lieutenant, Major, Colonel, General, and inspector. It is unclear if women are allowed in the Military Police. The only reference to a woman being in the military police is in Roger's Vision in "Roger the Wanderer" when Angel is in uniform.
The ranks of Colonel and below are field officers who organize defenses and investigate crimes. The only general seen is an office worker who is rarely seen.
In Season 2, Dan Dastun is promoted from Major to Colonel.
In ”Winter Night Phantom” we see the forensic science section.
Their uniform most resembles that of the US Highway Patrol and their badge resembles that of the US Army's Military Police.
They use handguns and rifles. Artillery, rockets, and missiles are used for the tanks and boats.
In Season 2, the Military Police change from rocket/missile firing tanks to shell firing tanks. Their main transportation is similar to Ford's Crown Victoria in the early 1990's. In “Bring Back My Ghost” they are shown to have a harbor patrol.
