Seung-ah-G218 (born Yoon Seung-ah; Korean: 윤승아; August 28, 2535) is a of the.

Early Childhood
Yoon Seung-ah was born in Saeloun Seoul, Reynif on August 28, 2535. When she was at the age of five, her father, a by the name of Yoon Hyeon-ki, left the planet to fight, leaving Seung-ah to live only with her mother for the next five years. While Seung-ah and her mother were enjoying family time in their home city's park, the Covenant invaded Reynif. Seung-ah's mother was killed by Covenant infantry, but not before she ordered her daughter to hide in the park's pavilion building.

Several hours later, Seung-ah was found by Dom-094, Sergeant Thomas Prado, and Lance Corporal Cynthia Sinquefield, who were also stranded in Saeloun Seoul. The SPARTAN called for evac, but a arrived at the park before any  transport could, and deployed. Dom-094 told Sinquefield to take Seung-ah deeper into the building, while he and Prado would fight the elites. The SPARTAN was able to kill all six zealots, but suffered burns from a few plasma bolts. Prado, unfortunately, did not survive the attack. A arrived soon after to pick up Reynif's last known survivors. Reynif was ultimately overrun, and subsequently.

Seung-ah was conscripted as part of the. She was trained by, , and and  on. During the training, she was assigned to Team Dao, along with Henry-G066, Jim-G067, Fred-G068, and April-G182. Seung-ah was clumsier than the other trainees, and her combat performance relative to her peers never got much better. However, she caught the attention of Petty Officer Third Class Aspen-B145, due to her ability to inspire strength in even the most pessimistic of allies. The older SPARTAN offered to train her to become a medic, which was something she willingly accepted. Both her natural empathy and her skills learned from Aspen would prove to be valuable assets to any ally she is around. Following the, Seung-ah was told that April did not survive the process, disheartening her.

Battle of Earth
Accompanied by Sam-015, Team Dao was aboard Kano Station during the. The SPARTANs defended the from boarding Covenant infantry. While treating a wounded marine, Seung-ah was shot thrice in the right side of her back by a. Although she did not flinch from her wounds due to the effects of the drug, Henry ordered Jim to escort her to the ship's, knowing that she had little time. When Kano Station took extensive damage, her cryo chamber was ejected along with others and landed on.

During the same time as the, her cryo chamber was recovered by UNSC forces. Her right lung was replaced with a newly flash-cloned one. Because of her condition, Seung-ah could not participate in the. She was brought to tears when she was told that the rest of Team Dao went on Kano Station. Soon, however, Henry-G066, Jim-G067, Fred-G068, and Sam-015 were recovered from Africa, having escaped Kano Station in an moments before the station's destruction.

Battle of Paradiso
"I never thought you'd be so handsome."

- Seung-ah-G218, teasing Dom-094, upon seeing him without armor for the first time

The Human-Covenant War left many civilians homeless. Paradiso was one of the newly-discovered habitable planets suitable for refugees. In the year 2554, Seung-ah-G218, along with Henry-G066 and Jim-G067, was sent to the planet with a set of refugees to ensure their safety from potential insurrectionist or Covenant attacks. They arrived on November 20, where they met up with Dom-094, who was already on Paradiso to watch over the first set of refugees.

Just three days after the SPARTAN-IIIs' arrival, a small fleet of Covenant Loyalists led by attacked the colony. The combination of the SPARTANs and a greater number of UNSC Army and Marine ground forces annihilated the Covenant ground forces. However, the brutes were able to successfully raid a camp that was not well-guarded, kidnapping none other than Seung-ah's very own father – Gunnery Sergeant Yoon, his surviving men, and the civilians at the camp. The battle in space was also in the UNSC's favor, thanks to the UNSC's greater number of vessels compared to that of the Covenant, forcing the latter's remaining ship, a single, to retreat. The crew aboard the UNSC Frigg was able to track down the Covenant ship and its destination – a world controlled by a relatively small number of Covenant loyalist remnants. Alexey Surkov ordered the Frigg and the majority of the Paradiso fleet to pursue in order to finish off the loyalist remnants and rescue the missing humans.

Battle of Beimeni
"He's dead, Jim."

- Seung-ah-G218 to Jim-G067, as the latter continues to mutilate a corpse

Upon arriving at the planet the Covenant escaped to, Surkov's fleet faced another battlecruiser, with the escaping battlecruiser nowhere to be found. As the brutes had captured several humans, Surkov did not order immediate orbital bombardment. Shortly after the UNSC's arrival, the missing battlecruiser emerged from the planet's atmosphere, indicating that it had likely deployed its prisoners at the planet's surface. Surkov ordered the SPARTANs and a division of infantry to search for and rescue the captured humans.

The Frigg's AI, Nótt, located the  of the captured Marines, and the UNSC ground forces subsequently rushed to the location. With the SPARTANs, led by Dom-094, spearheading the operation, the UNSC forces made their way to the prisoners, killing any enemy that stood in their way. Just before the SPARTANs could reach the prisoners, they arrived at the Covenant base's control room, where Tisamenus, the leading the Covenant forces, waited for them. The chieftain mocked the SPARTANs by telling them he had already killed one of their kind, even pointing to her armor he had on display in the room. Dom-094, then nonchalantly ordered Henry-G066 and Jim-G067 to unload weapons on Tisamenus. Dom-094 and the two other male SPARTANs, equipped with  weapons, obliterated the chieftain long before he could reach them with his. Among the chieftain's charred remains, Jim-G067 recovered his weapon, a. With their biggest threat eliminated, the SPARTANs proceeded to free the prisoners. The UNSC forces escorted the civilians to the nearest extraction with Jim-G067 in front, plowing through brutes and with his new weapon. Once all UNSC forces evacuated the planet, Surkov ordered the orbital bombardment of the Covenant bases on the surface.

Personality and traits
Seung-ah is best known for her very friendly and sociable personality which often boosts the morale of her allies. Due to her relative lack of combat ability among the Gamma Company SPARTANs, Seung-ah initially had difficulty finding her place among her peers. Her communication skills, however, caught the attention of Aspen-B145, who took it upon himself to train her as a medic. The older SPARTAN's decision proved to have paid off; Seung-ah had since gained a reputation of keeping almost all wounded allies alive long enough to receive proper medical attention, regardless of how terrible the injuries are. Those who have been treated by her describe her as "an angelic, reassuring presence" or "giving off a soothing aura."

Equipment

Seung-ah's new armor also has the installed, which in conjunction with her Resolute VISR, allows her to heal her allies even more effectively.

Seung-ah-G218 is also notable for often carrying in addition to. As a battlefield medic, Seung-ah-G218 always carries a when deployed in an engagement, using its contents to temporarily treat wounded allies.
