Years after the country defeat and occupation period, Japan is still recovering. Although they are on the road back to mass industrialization and prosperity, strong handed economic and political policies have turned many areas into dilapidated slums. Anarchists and anti-government student protesters have taken up arms, stirring up violent social revolution riots. In order to combat this growing threat, the Japanese government has nationalized a division of the police, creating the Capital Police Organization (CAPO). The CAPO 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.

Note: Loosely adapted into the anime movie Jin-Roh: The Wolf Brigade in 1999 which is also written by Mamoru Oshii.
