BirthOfASpartan - Augmentation

A screen monitoring Carter-A259's augmentations.

Project: CHRYSANTHEMUM is a set of SPARTAN-III bio-augmentation procedures, similar to those of the SPARTAN-IIs.[1] With advances in technology, however, the casualty rate for SPARTAN-III candidates was 0%, as opposed to the 56% casualty rate of the SPARTAN-IIs.[1]


Drug Description Effect
8942-LQ99 "carbide ceramic ossification catalyst" drug.[1] Skeletons become virtually unbreakable, allowing survival in harder impacts.
88005-MX77 "fibroid muscular protein complex" drug.[1] Increased density of individual's muscles, allowing heavier lifting.
88947-OP24 "retina-inversion stabilizer" drug.[1] Color sharpness is significantly improved upon, and night vision is adapted.
87556-UD61 improve the colloidal neural disunification solution[1] Greatly improves the individual's reaction time, decreasing the time taken to react by 300%. "Spartan time".

Gamma company also received the following in addition to the above.

Drug Description Effect
009127-PX (cyclodexione-4) bipolar integration drug Counters the effects of 009762-OO.[1][2][note 1]
009762-OO Neural-altering non-carcinogenic mutagen. Alters key regions in the individual's frontal lobe.[1][2][note 1] Enhances aggressive response to dangerous levels. Requires regular doses of 009127-PX and 009927-DG to be taken to avoid uncontrollable aggression.[2]
009927-DG miso-olanzapine Counters the psychological effects of 009762-OO.[1][2][note 1]

In Comparison To Spartan-IIsEdit

“This was always the moment when Mendez fully appreciated just how different a SPARTAN-II was from a regular soldier and even from the SPARTAN-IIIs.”

SPARTAN-III candidates came from a much wider gene pool than SPARTAN-II Program candidates did. Unlike the SPARTAN-III's, all the SPARTAN-II candidates possessed "perfect" genes that allowed their augmentations to have the greatest effects. This means that, even though the SPARTAN-IIIs received most of the SPARTAN-IIs augmentations (Other than the Catalytic Thyroid Implant, which produced significant gain in muscle mass and strengthened bone structure), the "perfect" genes of the SPARTAN-II candidates produced superior results.

For example, as stated in Halo: Ghosts of Onyx the augmentation that supposedly gave SPARTAN-IIs a 300% boost in reflexes (Superconducting Fibrification of Neural Dendrites) in reality caused a 1400% boost in reflexes, due to the genes of the SPARTAN-II candidates.

S-IIIs were chosen from a wider gene pool than the S-IIs, and they were were augmented chemically which produced a high variety in body sizes. There were S-IIIs who were as small as baseline marines, then there were S-IIIs as tall as S-IIs. All of the S-IIs were given a Thyroid implant which increased their height and muscle size, with that said some S-IIIs achieved the same body sizes as the S-IIs because of their genes and also physical excersise. Just like there are varying body sizes among normal people there is no reason to believe that all S-IIIs were physically inferior to the S-IIs, it depends on the individual.


During the battle of Pegasi Delta, Tom-B292, 12 years old at the time and equipped only with SPI Armor, engaged a Covenant Elite armed with a Plasma Pistol and an Energy sword in hand to hand combat. The Spartan's enhanced reflexes allowed him to dodge a Plasma Pistol bolt and sword swing at point blank range. He then proceeded to throw the Elite to the ground and finish it off with his Assault Rifle. It is also stated that during the battle, Elites and Jackals moved out of cover because they realized that it was suicide to face Spartans in close quarters.

Spartan-IIIs were also described to have been moving with "speed and reflexes that no Covenant could follow". "They dodged, snapped necks and limbs, and with captured energy swords, they cut through the enemy until the field ran with rivers of gore and blue blood". The 300 or so Spartan-IIIs faced thousands upon thousands of Covenant, including Covenant air support, and were described to have been winning the battle until 7 Covenant Cruisers emerged as reinforcements.

It was stated by Mendez that as Spartans grew older, they only grew stronger and faster as their bodies grew accustomed to their augmentations. During the battle on Pegasi Delta, Beta Company ranged from age 7 through 12. If the Spartan-IIIs lived long enough to mature, their physical abilities and body sizes would have improved significantly.
