Team Delta

Team Delta was a splinter team of the Spartan-II Red Team of the United Nations Space Command.

Introduction
Team Delta was the medium sized splinter team and consisted of six Spartans and four Marines. The Spartans were the ones wounded in the jump from Pelican Bravo-001, the members were Willaim-043, Isaac-039, Vinh-030 and three other Spartans and the four Marines of Charlie Company.

Reach
After the blotched landing on Reach which caused the death of four Spartans and securing the Orbital Defense Generators, Red Team split up and Team Delta was ordered to take several Warthogs and the survivors of Charlie Company to secure the Spartan fallback point that was CASTLE Base. William, Isaac and Vinh were separated from the other Spartans and the Marines and fell back to CASTLE Base. The team secured a way down to the base's front door, as the elevator had been destroyed. They were stuck outside the door until the remainder of Team Alpha used Oly Oly Oxen Free to open the door, which worked, and inside they found Doctor Catherine Halsey.

CASTLE Base
Inside CASTLE Base, Dr. Halsey treated their wounds and sent them on errands for things like extra armour and the prototype weapons that were there. Soon after, the Covenant started their offensive on the base and Dr. Halsey was forced to activate Operation: WHITE GLOVE and blow the base up, forcing the team down into the titanium mines below the base. Having wondered the mines, Fredric-104 found a Forerunner tunnel that led to a massive, twelve story, Forerunner cavern, with contained a strange Forerunner Crystal.

Rescue
In the massive cavern, the two teams came under attack by the Covenant, causing the them to retreat into a tunnel, which was sealed when two satchel charges go off and Isaac and Vinh disappear. Some time later, they group was rescued when the tunnel came unblocked by an explosion. On the other side they found John-117, Sergeant MajorAvery Johnson, Vice Admiral Danforth Whitcomb, Team Gamma and an ODST called CorporalLocklear. After a brief battle with the Covenant, they escaped in a Spirit dropship to the UNSC controlled ‘’Ascendant Justice’’.

Slipspace Battle
When the ship jumped into Slipspace, the Forerunner Crystal, found on Reach, distorted Slipspace and several other Covenant cruisers were engulfed in the bubble and a vicious space battle started. The shots from the cruisers disappeared and reappeared in random places and destroyed several of the Covenant ships. On board the Ascendant Justice, several rogue units of Elites sabotaged the ships' plasma conduit, forcing the Spartans to perform a dangerous space mission to repair it. When a rogue plasma torpedo hit the dropship, Spartans Anton-044, Li-008 and Petty Officer Second Class Polaski were killed. Their ship then dropped out of the bubble and back into normal space.

Operation: FIRST STRIKE
The remnants of Team Delta then preceded to help John-117 in the carrying out of his well planned Operation: First Strike. This involved the Spartans overloading the power core of the Covenant space station Unyielding Hierophant and destroying 500 Covenant capital ships. The operation was going well until the group came under attack by a pack of the ape-like Brutes and Grace-093 was killed. The Master Chief overloaded the core and destroyed the ship and almost all of the 500 ships.

First Battle of Earth
The remaining Spartans were assigned with the defense of Earth when the Covenant attacked. The Spartans were sent to numerous places throughout the course of the battle, including Antarctica, the sea floor and, most recently, to Cuba, to defend the last Space Elevator and the cargo of nukes there. The Spartans successfully took the Space Elevator and were soon reassigned by Lord Hood.

Onyx
Lord Hood reassigned the remaining Spartans to Onyx, to help with the defense of the planet. Soon after arrival, they came under attack by several groups of Sentinels and were forced underground by the attacking Covenant. Along with the help of Kurt-051 an the Spartan-IIIs   Ash, Olivia, Mark,Tom, Lucy,Holly and Dante, they repulsed the Covenant and destroyed three Sentinel production plants, before hunkering down at the top of a pyramid. The Spartans set up traps all over the base, but these were soon destroyed by the Grunts. A pair of Hunters made it to the top and would have killed Kelly, had it not been for Holly’s sacrifice. Will then engaged one of the Hunters and killed it in hand-to-hand combat while the others watched in amazement. Will was killed when the other Hunter shot him front on with its Fuel Rod Gun.
