Notable Attacks/Techniques:

  • CQC: Unique and highly efficient martial arts allowing a soldier a variety of options while not denying them the use of weapons. It generally has the user taking a stance with a knife and a handgun; thus, he/she could grab/throw opponents in melee, threaten/execute people with the sharp blade or shoot down opponents who are otherwise outside the user's range. CQC mostly focuses on grabs, throws, and other methods to disarm the target, allowing one to take down enemies without killing them or use them as a human shield. A skilled practitioner can even "chain" throws, allowing to rapidly neutralize an entire group of soldiers. The Boss was one of the creators of the technique and developed it while training with Naked Snake. She used these techniques to overcome several situations until Naked Snake surpassed her in their final confrontation.
