Classified Intel Acquisition

Classified Intel Acquisition was an operation that was undertaken by the Militaires Sans Frontieres private military group, regarding classified intel that had been retrieved by one of their moles at a prison facility in Cuba, Brian.

Prelude
The mysterious Cipher-backed XOF ended up working at the prison facility in Cuba, allegedly as CIA agents. Their leader, a scarred man known only as Skull Face, proceeded to torture heavily one of the prisoners, also relaying to the suffering prisoner his past and his motives before telling him in vain not to die. Brian, a mole for MSF, ended up witnessing this and recorded the data on a cassette tape and encrypting it for analysis for his superiors.

Intel Acquisition
On December 21, 1974, at 18:08, Big Boss, the leader of MSF, personally infiltrated the base by stowing away on the back of a truck, noting the presence of several armed guards before locating Brian. However, because of the security being heightened to the extent that casual conversation would have risked blowing Brian's cover, Big Boss instead placed Brian in a chokehold and "interrogated" him so the latter could relay the tape or at least its location without drawing suspicion. Brian admitted that he doesn't have the tape on him, but assures him its close by and safe. He also attempted to warn Big Boss about XOF and Skull Face, but decided against it before telling Big Boss to put him in a sleeper-hold to ensure his cover remained intact. Big Boss deduced the specific location of the tape and proceeded to escape.

Aftermath
Afterwards, MSF decrypted the tape and became aware of Skull Face's existence.

Behind the scenes
The mission first appeared in the TGS 2013 daytime demo for Ground Zeroes, although the date was given as the day the demo was issued. The player could either escape via chopper or, if that fails, escape via a stolen jeep.
