Desperado Enforcement LLC.

 Desperado Enforcement LLC.' was a group that was involved in the events of 2023. One member, a short corpulent cyborg, abducted the leader of an African country that was recovering from a costly civil war, and then killed him onboard a train. Much of the organization is currently unknown, other than Colorado Senator Steven Armstrong having some involvement in the organization to the extent that, had anything tying him to the organization was uncovered, he'd have to face a grand jury.

Behind the scenes
Desperado Enforcement LLC. was first mentioned in the "leaked" Senator audio on the Make It Right viral marketing website, where Senator Armstrong mentions to his speechwriter that the grand jury's "got nothing that connects me with Desperado." Desperado made its first actual appearance in the E3 trailer for Metal Gear Rising: Revengeance.
