Dolphin

Dolphin was a presumably female member of the private military company Militaires Sans Frontières.

During a fight between deputy commander Kazuhira Miller and commander Big Boss in Mother Base's sauna due to the former's womanizing nature with two female members of MSF, resulting in the hospitalization of one of the female soldiers's boyfriend from witnessing it, and the latter reprimanding him for it due to his behavior setting a very bad example, Big Boss then accused Miller of sleeping with her and Elephant, although Miller denied it, resulting in the brawl being escalated as well as Paz Ortega Andrade witnessing it and recording the event in her diary tapes.

Behind the scenes
Gazelle was a character mentioned in the "Snake & Kaz (Sauna)" audio drama included in the CD Metal Gear Solid: Peace Walker - Heiwa to Wahei no Blues, which elaborated on an event alluded to by Paz in her eight diary entry.
