Kerberos Panzer Cop

Years after the country's defeat and occupation period, Japan is still recovering.
Although they may be on the road back to industrialization and prosperity,
strong handed economic and political decisions have turned many areas into dilapidated slums.
Anarchists and anti-government student protesters have taken up arms, stirring up violent social riots.
In order to combat this growing threat to their fraudulent power the Japanese government nationalizes
a Tokyo police division, creating the Capital Police Organization (CAPO).
It consists of hard-trained panzer troopers carrying heavy firearms and wearing special armor suits
called Protect Gear: this specialized unit is feared by anti-government groups, criminals and civilians alike.

First adapted into a live action by Mamoru Oshii in 1991.
Loosely adapted into the anime movie Jin-Roh: The Wolf Brigade in 1999, also written by Mamoru Oshii.
