Another theory:

XOF commander is Kojima's representation of an Oni, a mythological Japanese demon/ogre. If anyone watched the GZ trailer editied for day time, you'll notice that the XOF leader has blue skin, making him a "Blue Oni".

Volgin is being featured as a thematic link to the burned man as the dichotomous "Red Oni", and BB exhibits physical traits of both at the end of the MGSV trailer when he's on the motorcycle.
