Civil War has ravaged the nation; the federal government is gone, states exists as sovereign state nations.  In the wake of chaos, a new power, “New Colonia” emerges, keen on uniting the former U.S. under their banner and the protection of their "Garrison" military and the privately held SWARM security forces!  Those who resist band together and form the “RSS or Resistant Sovereign States” to fight against New Colonia. The RSS creates a special military unit, an "Action Force" to help fight!
