Peace exists for a reason. So do those on the other side.
Its mission is war deterrence, conflict intervention, and ceasefire maintenance, functioning as an international military organization to prevent all-out war between major powers.
While global warfare decreased due to UN activities, the massive military-industrial complex and related corporations in the United States were forced into a major turning point.
Amidst this, suspicions surface that US government agencies, the military, intelligence services, and corporations may be involved in some form in the small-scale conflicts, terrorism, and coups occurring worldwide.
To uncover the truth, the UN orders an investigation by the United Nations Force Bureau 4, a secret special operations group and the only unit authorized to assassinate or arrest high-value targets.

Galileo Galilei
War has vanished.
Following repeated international conflicts, nations across the globe entrusted a portion of their military power to the UN.
The world's first permanent UN Force.
Its role is not to fight. It is to ensure war never begins.
Detecting signs of aggression, containing conflicts, and if necessary, enforcing ceasefires through military force.
Since the creation of the UN Force, no all-out war between major powers has occurred.
The world has become peaceful.
───At least, on paper.
The change appeared in small conflicts around the globe.
Massive amounts of weapons flow in just before a ceasefire. Armed groups suddenly expand their influence right after a peace treaty is signed. Weapons that shouldn't exist are confirmed on the battlefield.
And each time, the presence of US defense contractors and government officials surfaces.
However, there is no evidence of illegal activity.
