The Major

The Major is the assumed identity of a Private Force stationed in the Angola-Zaire border region of Angola. He wore aviator sunglasses.

Biography
The Major was paid to spread a rumor claiming he had the sale of nuclear arms materials by an unknown client. As all of his instructions came from a cut-out, even he didn't know the identity of his employer. At some point, a subordinate of his, who was actually an undercover agent of the Contracted Forces of Africa, intended to meet with him so he could investigate a group known as the ZRS, due to having suspicions about the nuclear arms trade's connection to yellowcake being distributed. Venom Snake, the leader of Diamond Dogs, proceeded to tail him to find the Major, as he was contracted to assassinate him. The Diamond Dogs later learned that he was paid to spread the rumor, with Miller suspecting that Cipher was the Major's client and that there was a connection between Zero Risk Security, Inc. and the yellowcake the Diamond Dogs uncovered in an earlier mission to steal a truck. Miller also learned that the ZRS was also tasked with killing an old man, causing Miller to wonder how the old man got that important.

Behind the scenes
The Major is a key character in the mission "On the Trail" in Metal Gear Solid V: The Phantom Pain. The player can either kill him or otherwise extract him. If the player chose to do the latter, the debriefing will have Miller relay that the major revealed all he knew from interrogation, as well as learning that the ZRS was planning to kill an old man.
