A number of soldiers who once belonged to the world-leading Special Forces joined 'Global Risk', the international mercenary forces corporation. The mercenaries carried out difficult missions for the organization, but they have distinctive differences from 'Black List' who commit terror only for profit. Despite an appreciable sum of money, the mercenaries have never participated in any battle without justifiable reasons and they live up to their conviction to fight against terrorists. Based on their practical battle experiences and skills, Global Risk seeks to expand its power. Main clients of Global Risk are third world countries without their own national militaries, countries on the black list of terrorists, and the UN X-File Bureau implementing secret missions.
