Vinh-030

One of the Spartan-II supersoldiers, Vinh is not well known among the Spartans, likely because she did not seem to have a close relationship with either John-117 or Fredric-104.

Childhood
Vinh was conscripted into the SPARTAN-II program in 2517 at age 6, when Dr. Catherine  Elizabeth Halsey singled her out as a physically and intellectually superior child. She was abducted from her home and replaced with a flash clone. She was then taken to Reach where she was trained with the rest of the Spartan soldiers by Deja and Chief Petty Officer Franklin Mendez.

Reach
Vinh was never mentioned by name until the concurrent Battle of Reach in 2552. She was assigned to Red Team, under charge and leadership of Fred. They were assigned as shock infantry to the surface of Reach, to defend the generators for the orbital MAC guns. As they descended, their Pelican, Bravo 001, was hit and the Spartans were forced to jump from the crashing vessel. Vinh was wounded during this jump, suffering a torn deltoid muscle, three broken fingers, and a herniated disk.

She was then assigned to Delta Team by Fred, under charge of Will-043. Their mission was to secure the fallback position for the Spartans: CASTLE Base. Vinh, Will, and Isaac-039 were separated from three other Spartans and the remaining members of Charlie Company but arrived at CASTLE Base. They were unable to enter the facility until Fred and Kelly-087 met up with them and Kelly whispered Oly Oly Oxen Free into the speaker of the facility. Dr. Catherine Halsey was present, and opened the door for them. She was then checked out by Dr. Halsey and sent to survey perimeter defenses for the facility. This proved unnecessary however, as the Covenant attacked immediately.

Disappearance
Vinh, Isaac, Fred, Kelly, Will, and Dr. Catherine Elizabeth Halsey were then trapped under CASTLE Base for several days after Halsey activated Operation: WHITE GLOVE to destroy the base, and to keep it from falling into enemy hands. Vinh was able to upgrade her MJOLNIR armor with parts salvaged from the base. These upgrades were being conducted in field-testing and had yet to be certified. Vinh received a new linear accelerator added to her shield system, essentially doubling its shielding output.

After Fred discovered the massive room containing the Forerunner Crystal, it sent a massive radiation spike that allowed the Covenant to triangulate on the group's position. A Covenant Gravity Lift quickly appeared. The group retreated to a nearby tunnel, as Vinh and Isaac dropped Satchel Charges to cover the Spartan's tracks. The Charges detonated, but Vinh and Isaac disappeared. They could not be raised on the COM and it is highly likely that they are dead. Vinh is listed as MIA, but is assumed to be KIA. There is a chance that Vinh was captured by the Covenant along with Isaac-039 and may reappear later on.

Trivia

 * After Joshua's assumed death, Vinh took his serial number, SPARTAN-29, although this could be a typo.
