A.R.G.U.S. is a United States federal agency operating under the jurisdiction of Homeland Security. It is under the command of Col. Steve Trevor and Director Amanda Waller.
It is introduced in The New 52 (a reboot of DC Comics continuity) following Darkseid's invasion. A.R.G.U.S. acts as support and liaison to the Justice League, supplying them with resources and cleaning up afterwards. Trevor was asked to stand down as head liaison after their battle with Graves, having gotten too close to Wonder Woman.
