Chapter 1: Assessment

The room was dark, not pitch dark… but dim. The lighting had been shut off by the rooms occupant, the only lighting illuminating the room was a single lance of light cast from the computer terminal built into his desk. His eyes burned from looking at the damned screen for hours, so he had hit the lights and leaned back in his black velvet chair and closed his eyes to sooth the pain… he needed rest, the rate at which he had been working was staggering for his age.

But he couldn't rest… not now…

Humanity needed a guiding hand, humanity needed him. One of the few level headed personnel high up in the command chain of the UNSC. He knew his duty; he knew what he had to do.

Lord Terrance Hood had been reviewing battle reports from nearly all his command staff, he had started, but there was still much that needed to be looked at. Personnel losses, ship losses, enemy losses, equipment losses… so many losses.

Beep

He looked down at the keyboard, careful to avoid laying eyes on the screen and saw a little red light blinking. He had received a message of course, but the light was red, not green or orange or yellow; that meant this transmission was important, this was something he had to read. He sighed, disappointed at being disturbed in his momentary break.

"Lights. Full." He stated simply.

The sudden brightness was nothing Lord Hood wasn't used too, and returned his eyes to the computer monitor and clicked on the new message sign. After putting in a series of access keys and passwords, he finally opened the transmission.

Due to recent events such as the attack on Earth, it is now clear the Covenant know the location of our primary military world. Even with the presence of 300 orbital MAC guns, Covenant forces still managed to penetrate the orbital defense grid and land ground forces on Earth, which resulted in the destruction of a major population center (light damage compared to nearly all previous engagements).

However, while property damage was great, life losses were low thanks to the quick and responsive deployment of Spartan 117. By punching a devastating hole into Covenant defensive line and grasping enemy attention, all civilian and non-combat personnel were evacuated, as well as putting a minimal loss on combat ground forces and equipment.

But the fact remains the same, the Covenant know we're here, and next time they'll come in force, maybe a force that was even bigger then the one that destroyed Reach. But due to the desperate attempt to break through the orbital defense grid, rather than there usual suicidal method of trying to kill everything they can. Combined with Intel from few previous engagements, it has been reported that sometimes the Covenant did not immediately start orbital bombardment, or still yet when remaining UNSC forces jumped out of system, these planets are presumed to have been glassed, but no proved Intel has been returned to the status of these planets. The main point of this is that the Covenant wants something with Earth, something planet side.

Due to this new threat, I have seen it fit to send my newest Spartan Project, codenamed Spartan Centurions, to protect ground side MAC guns and generators.

This new Spartan units main purpose is to provide heavy support to the remaining Spartans of Alpha Company, ranging from intense covering fire to mobile cover. Sadly though, the genetic augmentation to the Spartan Centurions was far more risky to that of the Spartan IIs. Out of the 40 initial subjects, only 3 survived the augmentation. I have attached files concerning their performance, equipment, and skills.

Use these assets to your discretion Admiral, and apply them to their prime elements, I'm sure you'll be more then satisfied with the results. As for the Spartan IIs themselves, they will not be joining in on defending Earth; I have them in need of 'another' matter.

Research Report A0712-UNSC WEACORP

Subject: Spartan Centurion Overview

Reporting Officer: CPO DuVal, UNSC WEACORP/ UNSCMID: 033278292

The Spartan Centurion augmentation procedure is rather different then Spartan II augmentation procedure. Though all the same altering chemicals are used, Spartan Centurions have different amounts of said chemicals.

The Carbide Ceramic Ossification material used to harden Spartan bones until they are like steel bands has been tripled, to the point where they can successfully absorb archer missile impacts directly without breaking. This allows them fall considerable distances without serious bodily damage.

The Catalytic thyroid implant has also been tripled, for this the Spartans are far larger then your average human, standing 9 feet tall at a minimum, this was required for the extra muscle mass that is needed for the main intent of Spartan Centurions.

The muscular enhancing protein complex injection however was the biggest difference, at a sturdy 10x the amount of regular Spartan IIs, it was required for the field of work that would be required of them and is the main reason so few survived the augmentation. Needed to operate the equipment they would need. This intense strength allows them demolish buildings with there bare hands, throw large objects such as civilian cars or chucks of debris to disorient enemies, overturn anything as heavy as a Scorpion MBT too perhaps use as cover, and gives them the ability to make heavy defensive positions in minutes.

However, the superconducting fibrification of neural dendrites and the Occipital Capillary Reversal procedures have been considerably lessened. They are not as fast or versatile as the Spartan IIs, their reflexes, though still considerably well, are not as good as Spartan IIs, and there eye site isn't up to par with Spartan II standards, just enough to not trouble them in night conditions and see an acceptable extra distance. Equipment has been built to counteract the deficiencies in armor systems; however, these particular skills will not measure up to Spartan IIs under any circumstance, even with the presence of armor systems.

Technology Report A1012-UNSC WEACORP

Subject: Spartan Centurion Equipment

Reporting Officer: CPO Beckett, UNSC WEACORP, UNSCMID: 022371238

The Spartan Centurions armor systems are suited just for their needs and are equipped with the best technology to date using human, Covenant, and in far fetch way, Forerunner technology.

There armor systems include a heavy duty rechargeable shield battery, meant to withstand waves of either bullet or plasma fire. Fiber optic wiring, two layers of ballistic cooling gel, Internal cooling systems, built in melee weapons in each forearm, motion sensor, a miniature built in 'dumb' AI to organize and provide tactical intelligence and combat conditions. A flexible, durable, and airtight advanced Kevlar jumpsuit underneath armor plating that contains 6 hours of extra air (Compressed into air tanks that are fed from inside the armor) in space conditions . Many over lapping armor plates made from a super dense heat absorbing metal short named Tri-titanium S that is created by melting titanium in a superheated melting chamber to form a Titanium gas, is then introduced and dissolved into a liquidized Carbon mixture with trace amounts of other required elements and exposed to extreme pressure. The resulting product is a very physical and heat resistant diamond like Titanium compound. All together there heavy defensive armor systems come in at total weight of 7.02tonnes

The Most fetching feature of the Spartan Centurions armor systems though is the ammunition supply system. Using data recovered from 'smart' AI Cortana during her stay with Spartan 117 on Halo, we were able to organize the complex calculations, physics, and technological requirements in order to transport objects like the so called '343 Guilty Spark'. However, our developed technology isn't nearly as good that on the Halo construct, we can still transport small objects within 3 x 3 foot radius a good distance with perfect precision, these objects include ammunition.

The Centurions can manipulate what type ammunition they wish to be transported by tapping there fingers against their palms, each finger opening a direct category, and then pick what kind of ammo they need from a subcategory from there. This system allows the Spartan Centurions to lay massive amounts of fire power down without much consequence. However, this feature requires a specialized ship or facility to constantly provide them with ammunition. Should said method become compromised, it puts the Centurions at a considerable disadvantage and they may have to resort to hand-to-hand combat for an extended period of time. In missions where the ship may not be able to say for a prolonged period of time, the Spartan Centurions carry large backpacks for there munitions.

The Spartan Centurions use specialized firearms due to there size, and there are not many in number, here is a list along with a basic description.

The ML18 Gatling Gun – Meant to be one of the standard weapons for all Centurion Spartans. A .30 Caliber 5 barreled rapid fire chain gun capable of firing approximately 83 of rounds per second and totaling at 5000 rounds per minute, clip size contains exactly 5000 rounds. After tweaking with Covenant weaponry, we have found a way for all rounds to be flash charged with plasma, giving them even more lethal power, this feature can be shut off for it can leave a slight blue trail from the glowing blue bullet. Their size, armor, and augmentation allows them to deal with the intense recoil of the gun.

The AR-87A Carbine – The equivalent of a marine assault rifle, this gun is good for prolonged enemy exposure at medium range, carrying 300 rounds of 0.75 Caliber rounds that can also be flash charged with plasma, this gun allows the Spartans too outlast any enemy in a prolonged medium range engagement. This weapon has a good deal of accuracy and comes with a medium range scope and has the 3 standard modes of fire. Comes with 1 slot for a shot gun, grenade launcher, or bayonet attachment.

The VS2 Anti-Tank Rifle (ATR) – An Anti-Tank Rifle that works in close, medium, and far ranges, this shocking 1.20 Caliber rifle can put a hole end through end in just about any vehicle short of a slip space capable starship. Using a miniature version of MAC technology, it launches the bullets using combustion and massive magnetic forces at velocities over 2.5km a second in atmosphere and faster yet in space. This gun can also be used as a sniper rifle, though the use for sniping individual targets is rare, the bullets fired are usually explosive rounds with the power of one standard fragmentation grenade, used for taking out clusters of enemies at a large distance. It has a 5 round clip, can be flash charged with plasma, grenade rounds cannot be flash charged, or else they'll explode.

The IR-1 Flame Thrower – This Flame thrower uses a special butane mix or plasma cells, and supplies any flame with plenty of extra oxygen to ensure complete combustion. The blue flames can lower standard grade Covenant shields and eliminate standard infantry quickly and effectively. The flames have a maximum range of 50 yards. Can spray hotter plasma flames, but at a radius of only 20 yards.

The KK-A2 Magnum – The standard sidearm of a Spartan Centurion. An .80 Caliber magnum pistol powerful enough to destroy light vehicles. It is used very rarely, but it is proven to be very reliable and accurate. Comes with a 2x scope, and is the only Spartan Centurion weapon to come with a silencer (the silencer is one foot long, its length is to ensure complete silence when fired). 8 bullet capacity. Can be flash charged with plasma.

The AS-SC12 Auto Shotgun – A large automatic shotgun that contains standard 8 gauge slugs, anything higher and the recoil from the constant firing will best even the Centurions. One wheel shaped clip contains 36 slugs of various ammunition types. Devastatingly effective in enclosed spaces.

The SSRM-SC1 Rocket Launcher – This rocket launcher is capable of firing both rockets and RPGs, it has 3 missile tubes, 2 for the heavy duty Spartan munitions, and 1 tube that fires 1 standard sized rocket for immediate emergency use. Can fire plasma explosives and can track moving targets at a considerable distance. The heavy duty munitions have enough power to lower seraph shields with one rocket, and finish it with the next.

Naval Technology Report A1418-UNSC WEACORP

Subject: Spartan Centurion Supply and Support Ship

Reporting Officer: CPO Clyde, UNSC WEACORP, UNSCMID: 037478738

The Spartan Centurions are basically in need of a mobile munitions plant, otherwise their uses diminish, that is why we have taken the liberty into turning an out-of-date Phoenix-class light frigate into a specialized mobile armory for the Spartan Centurions; this ship has been dubbed Dark Whisper by Dr. Halsey. Its planned construction began as soon as the Spartan Centurion project was about halfway done, so the ship would be able to fit with the best gear available. It has taken approximately 4 and half years to complete retrofitting and still gets updated technology installed on a regular basis.

First of all, the teleporting technology took a massive amount of space, so we had to take out nearly 3 quarters of the crew bunks on the ship as well as three of the five cafeterias and an equipment repair shop to maximize on cargo space. With the more then tripled space, we were able to install the teleporting technology and have plenty of space for the Centurion's ammunition.

The 3 Hangers each contain 2 modified pelicans each, while the 1 remaining vehicle bay contains 12 warthogs designed from the ground up to support the Spartan Centurion's combined weight. The car in itself is over 6 times heavier then the standard warthog due to all the metal need to make a sturdy chassis and frame, and an engine powerful enough to transport the Spartan Centurions in a manner that was faster then they could run if air support was not available. The warthogs still have the 3 standard positions of a gunner, driver, and passenger.

The remaining space is for the crew of the ship, which used to be a compliment of 450, has now been reduced to 120 personnel, consisting of 16 command staff, 67 standard crewmen such engineers, technicians, and repairmen, 7 medical crew, and 1 small platoon of 30 military personnel in case if the ship ever gets boarded, plus the 3 Spartan Centurions. The rest of the space is crew quarters, a machine shop, 2 cafeterias, a standard marine armory, a briefing room, wash facilities, advanced medical facility, bridge, engine room, recreational area, and other ship required facilities.

Extra space in the MAC cannon area was used to make a giant version of an elite stealth generator. Though the first many versions failed, a working version was finally achieved and installed upon the ship. It isn't perfect due to our limited understanding on how it exactly works. The hull armor plating has also been expanded to two meters in thickness instead of one and has been honeycombed on the inside like it was on the Pillar of Autumn, to allow it to take a good beating. However, due to the size of the ship, a volley of plasma torpedoes from a Covenant heavy cruiser will be more then sufficient in destroying it, depending if all shots hit, which is extremely unlikely due to the advanced engines of the Dark Whisper. The hull is also coated in the same radar bouncing material on ONI prowler ships, making the cloaked ship just seem like a subspace echo. All this allows the ship to be extremely well hidden and stealthy, allowing for more continued support of the Spartan Centurions under dangerous conditions. All hallways and access hatches have been enlarged to allow the Spartan Centurions easy access to all areas of the ship.

All primary defenses on the ship were removed to allow for more space in the ship for the cloaking generator. All that remains for ship defenses are 25 light craft defenses, however the standard 50mm cannons have been modified to be like most Spartan Centurion weapons. All 25 50mm rotary cannons can now fire rounds that are flash charged with plasma

Lord Hood looked at the monitor with a blank expression on his face, not surprised that something of this nature happened, for he had been expecting it for a while. However, being human, he was still curious.

"What are you planning Halsey…" He thought, "What are you trying to do…"

A.N.: I hope it wasn't too long and boring, but I think it was necessary. Now try and remember these new Spartans are not supposed to better then the Spartan IIs in every way and I try to make it so for every powerful advantage they have, it can also have severe drawbacks. So for every strength, they have a weakness as well.

A.N.: Be sure to point out any mistakes, as I want this to be perfect.
