A.R.G.U.S.

Advanced Research Group United Support, initialized as A.R.G.U.S., is a research group running in the United States and special opts division of the government, taking down terrorist threats in secrecy and without public knowledge. Despite this they are willing to let vigilantes such as Green Arrow and The Flash operate without interference, as their work does benefit their respective cities they operate in.

History
A.R.G.U.S was formed by a group of corrupt officials in the U.S. government to deal with major threats like the League of Assassins, H.I.V.E. 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 identify A.R.G.U.S agents simply by it from his past experience with them.

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.

Overview
Under the leadership of the amoral Amanda Waller, the organization became very questionable if not excessive in its methods, at times becoming no better than the very threats they are supposed to protect the U.S. from, committing unspeakable acts with no regard for human life. This includes the extortion of whomever is convenient to their benefits, usually threatening their family members if they don't comply. They also used felons for Task Force X to carry out life-threatening operations in exchange for working off their sentencing.

Following the death of Amanda, Lyla Michaels becomes the new director of A.R.G.U.S., reforming the organization, as everything they do is now based on morals, principles and the value of human life and no longer using criminals or unwilling individuals for their benefit. It also seeks to cure criminals of their powers rather than weaponize them.
