Subject: Fireteam No. 2547. Codename "Vertigo"

Fireteam Vertigo was a highly classified Special Operations Team consisting of 5 members, serving aboard the UNSC Marder. Vertigo was created in the aftermath of the Human-Covenant war in 2552 as a means to help prevent situations like the aforementioned war in the future, along with other teams such as Kilo-Five. Knowing that humanity would not survive another war like the Human-Covenant war, Vertigo was composed completely out of surviving Spartans. They used codenames named after various demons, as they said, "They called us demons, so we'll become demons."

Leading the team was Oliver A-019 (Codename: Eblis), a Spartan III designated as a
Hyper-Lethal Vector by the Office of Naval Intelligence and was personally recommended for the team by Admiral Hood, who had witnessed A-019's combat prowess and tactical ability. The appointed second-in-command was Jaclyn A-078 (Codename: Barbatos), an unrivaled sniper and deemed fit for the role by Oliver A-019 himself as well as by the Office of Naval Intelligence. She was originally considered for the role of squad leader, but it was quickly decided against because of her short temper and inability to make fast tactical decisions. The Close-Quarters Combat (CQC) Specialist was Ezra A-156 (Codename: Balrog), who preferred to use melee weapons such as the T-2 Gravity Hammer. He was the largest of the five Spartans, and was diagnosed with acromegaly, or "giantism", the disease that 20th-century popular culture idol Andre the Giant suffered from that causes an excessive amount of growth hormones to be secreted. He was fortunately cured of this condition during Spartan augmentations, as a special chemical was added to suppress the disease. The Combat Engineer and heavy weapons specialist was Katherine A-295 (Codename: Abraxas). She was the smartest of the Alpha Company Spartans and was naturally pulled aside for Category II training. She was one of the designers for both the ARC-920 Railgun and the latest iteration of the Grindell/Galileian Nonlinear Rifle (GUNGNIR) Weapon System, dubbed the Spartan Laser by operators. She was originally slated for deployment with Operation: PROMETHEUS but was pulled out of the greater battalion because of her amazing intellect. Lastly is Kyle A-088 (Codename: Jarjacha), who was the Recon Specialist of the group, and was specialized for difficult terrain. A-088's family was of Terran Peruvian descent, and their culture was a big part of Kyle's off-duty lifestyle, hence his codename, "Jarjacha", a demonic dog that would roam the Peruvian Highlands in search of prey. He is the fastest of the group, clocking in at speeds of over 65 kph at a dedicated full sprint for short periods of time.

Fireteam Vertigo participated in several high-value and major raids through the years of 2552 to 2555. They were often deployed to destroy Covenant splinter sects and Regional Insurrectionist Chapters, with notable missions being the Raid on New Harvest, the First and Second Enceladus Uprisings, and the ill-fated raid on REDACTED which led to the quiet disbandment of the team. Ezra A-156 retired to REDACTED on the Outer Colonies at the age of 18, and his status is currently unknown, assumed alive. Jaclyn A-078 was reassigned to the Spartan IV program along with Kyle A-088 and are both currently active. Katherine A-295 was transferred to the Office of Naval Intelligence Engineering Division on account of her intellect. She is currently off of active combat. Lastly, Oliver A-019 was transferred to Office of Naval Intelligence Research & Development Department to field test experimental technology against the enemies of humanity. He disappeared during the Project Peregrine tests and is currently listed as M.I.A. and presumed dead. None of the squad members have heard anything from each other since Vertigo's disbandment.

Subject: UNSC Marder.

The UNSC Marder was a heavily modified UNSC Destroyer, used for specialized deployments and strikes. The Marder was stripped of almost everything and put back together as a new ship, one of three in the top-secret Manhattan Class Destroyer. The Marder was outfitted with several times the normal weaponry than most ships, outfitted with two high powered MAC Cannons, as well as a stripped and heavily modified Covenant point-defense system, 40 Archer Missile Tubes, and 10 Shiva Class Nuclear Warheads, earning it the title of "Gunboat." It utilized a powerful Ion-Engine Array that allowed it to reach speeds faster than most destroyers. The Marder served alongside her sister ships, the Oppenheimer, and the Howitzer, and all of them were allocated their own troop forces. Each ship was outfitted with one ODST Battalion, and one Spartan team along with dedicated support crew. The Marder was assigned the ODST Harbingers, and Fireteam Vertigo. During the course of its time in service from 2552 to 2555, the Marder served as a base of operations for the Harbingers and Vertigo and was often used as a mobile assault platform, using its twin MAC Cannons to obliterate targets from orbit. After the raid on REDACTED, the Manhattan Class ships were pulled from the front lines and eventually were docked in storage in 2557 after two years of nothing. The Marder is currently docked on Sanghelios as per a deal with the Arbiter to keep it away from prying eyes along with the other Manhattan ships.

UNSC Marder Status: Retired.

Subject: 78th ODST Group. A.K.A. The Harbingers.

The 78th Harbingers were a group of ODSTs that served onboard the UNSC Marder. The name Harbinger came from a long line of Harbingers before them, dating back as far as the 2300s, with the troops of the 78th being the last to receive the title. They were often dropped into high-stakes missions with only minimal supplies. They utilized more advanced technology that normal UNSC Marines and ODSTs and were capable of spending long periods of time behind enemy lines, which was their primary mission most of the time. Each Harbinger was said to have had the same training as Spartans, only without augmentations, and while they were physically weaker and, in most cases, not as tactical as their Spartan counterparts, they were very well trained and very deadly. They worked alongside Spartans such as Fireteam Vertigo on many occasions. However, during the raid on REDACTED, the Harbingers encountered heavy resistance and suffered heavy damage and lost over 60% of their soldiers. In the end, the 78th ODSTs were disbanded due to heavy casualties and the incidents that occurred during the raid. No new Harbingers have been chosen since.

The other files regarding the UNSC Marder and her crew have all been classified or destroyed. No trace of the aforementioned soldiers remains.

(A/N) As much as I hate to break character, I have to respond to a guest comment.

First of all, get an official account! This will let me respond to you properly instead of having to type out a long response at the end of a chapter.

So, the comment said Oliver A-019 should've beaten up Yang in the last chapter, and if it were some other fic, I would've wholeheartedly agreed. Ollie could probably beat Yang in that state easily, but that's not the point. The guy is trying to help the girls, not give them a horrible smackdown each time they mess up. His job is to make sure the girls make it through the school year, not put dents where their faces were. Are we good on that now? Ok. I'll see y'all later. Thanks for reading.

P.S. Did I go too edgy with the codenames being demons? Let me know. I did try to keep it light-hearted by naming a couple of the codenames after a couple demon lord from Dungeons and Dragons. If you can name then, good work.
