Mosquito Stinger Force

The Mosquito Stinger Force, shortened to just the MSF, is a 270+ man band of mercenaries organized by Mosquito, a former Militaires Sans Frontières member.

Its name, organization, equipment, and overall purpose is obviously supposed to reference the Militaires Sans Frontières.

They are minor antagonists in Metal Gear Solid V: The Phantom Pain.

History
After Militaires Sans Frontières was destroyed by XOF in 1975, one of the few survivors of the attack, Mosquito, went mad from the anxiety that a clean-up crew was possibly after him. He was also brainwashed by rumors that the attack was orchestrated by Big Boss himself, leading to a fiery hatred against the man. In retaliation, Mosquito spent the late 1970's and early 1980's building his own private military almost identical to the MSF. When the new MSF heard that the old MSF had been replaced by Big Boss with the Diamond Dogs, they launched a 20-man attack (including Mosquito) on the Diamond Dogs' command platform and took several staff hostage. Big Boss eventually defused the situation personally in Mission 22: Retake the Platform, and either killed Mosquito or corrected his misinformation and convinced him to join the Diamond Dogs. The player could then choose to wipe out the rest of the MSF by invading their FOBs.
