Advanced Research Group United Support

They're also the organization behind the formation of the Task Force X - felons working off their life sentences by running missions for

A.R.G.U.S.

A.R.G.U.S was formed by the U.S. government to deal with major threats like the League of Assassins or the Church of Blood, they also deal with highly dangerous criminals and recruit some of them for their Suicide Squad.

A.R.G.U.S has been using the same flanking patterns for years, so much so that Oliver was able to ID A.R.G.U.S agents simply by it from his past experience with them.

Unfortunately the organization became corrupted over the years, due to it being led by the immoral Amanda Waller.
Oliver has occasionally interfered in A.R.G.U.S. business, due to his bad experience with the organization, as he does not trust their intentions.
