The canonicity of this subject in the Metal Gear series is ambiguous.

An undercover agent was secretly planted by the United States military's Joint Chiefs of Staff (JCS) at Camp Omega sometime prior to December 21, 1974. 


In 1974, the agent was tasked by the JCS to uncover incriminating evidence that the Cuban base was being used as a black site. He eventually came into possession of a cassette tape that provided irrefutable proof that the base was being converted into an interrogation and internment compound under the guise of a refugee camp expansion.

On December 21, the agent was ordered to meet with the private military company Militaires Sans Frontières, who had been hired by the JCS via a cut-out, to supply them with the tape. MSF commander Big Boss infiltrated Camp Omega to meet him, although the risk of compromising them both to the enemy was too great for him to meet under normal circumstances. Big Boss instead utilized force to make contact with him, ensuring both their covers remained intact. The agent was thus ambushed and questioned at knife point by Big Boss, but he revealed that he didn't have the tape on him because he was being monitored, and had instead placed it in a "safe spot" in the central control tower. He also inferred that those monitoring him were not actually affiliated with the CIA, before wishing Big Boss good luck and asking that he quickly knock him unconscious to maintain his cover.[1]

Big Boss's lieutenant Kazuhira Miller radioed his suspicions of the tape's location and told Big Boss to watch himself.[2] True to Miller's suspicions, Big Boss later overheard the agent and a bald Marine talk about the central control tower being a trap.[3] The cassette tape was placed near a surveillance camera.[4] In addition, an armored vehicle arrived at the helipad while Big Boss was en route to the tower. Because of this, the agent was forcibly interrogated by Big Boss again, due to the possibility of a set up. He then revealed his cover had been blown and that the bald Marine was in possession of the tape they were looking for (implying the tape in the control tower was a decoy), containing the full details of XOF's activities. He also begged Big Boss not to kill him, as his family had been kidnapped and was used as leverage against him. Miller speculated that Cipher was responsible for the blackmail.[5] Both tapes were eventually recovered by Big Boss, who escaped the base with them, one of which contained a recording of an interrogation session conducted by Skull Face, the commander of the military group XOF.

Behind the scenes

The Undercover Agent first appeared in the TGS Daytime demo of Metal Gear Solid V: Ground Zeroes as a key element. Hideo Kojima identified him as Brian, due to his likeness being provided by a Kojima Productions Los Angeles animator named Brian Robison via facial motion capture. It was implied that while the overall premise would be in the game, Brian himself might not have appeared in the final version, due to him being planted for the demo. Ultimately, he does appear in the Side Op, Classified Intel Acquisition, though he is not named in the mission and is instead referred to as "Undercover Agent" in the mission's ending credits. What agency he worked for and happened to his family after the Side Op is not revealed. He is voiced by Roger Rose. If the player chooses to extract the JCS agent and/or the bald Marine, they can later be transferred over to The Phantom Pain as staff members despite the Side Op being a "pseudo-historical recreation."
