A drill instructor was a member of the mercenary group Militaires Sans Frontières in the 1970s. He conducted various exercises as part of MSF's training regimen, including the teaching of CQC techniques. As expected of his position, he was loud, quick, and sharp with the trainees, sometimes sarcastically suggesting that they kill themselves immediately if they couldn't use basic enemy evasion tactics. Like the other members of MSF, the instructor held great respect for the abilities of their commander, Big Boss.
