but i can say

HIstory:
XOF was involved in the imprisonment of the former child soldier Chico at Camp Omega, prompting a rescue effort from Big Boss of the Militaires Sans Frontières. They had also detained ex-Cipher agent Paz Ortega Andrade, 10 days after a Belizean fishing boat recovered her from sea, having held her for interrogation on behalf of her former employers.

After XOF's commander, Skull Face, visited Chico at Camp Omega, and told him to, "Give my regards to your Boss, when you get home," anticipating the arrival of Big Boss at Camp Omega, the group commenced their "Trojan Horse" operation; an assault on the MSF's Mother Base, under the guise of a UN nuclear inspection, though Big Boss, Kazuhira Miller, Huey, and other MSF soldiers were able to escape.

While undergoing their activities, XOF claimed to be a CIA-based unit. However, one of the MSF's moles, a United States Marine Corps member named Brian, uncovered and likewise relayed to Big Boss that XOF was not actually aligned with the CIA at all.
