{{Quote|You are Spartans now. You stand side by side with your Spartan brothers and sisters. You march into battle together--you do not charge ahead. You do not grab glory for yourself. Spartans don't have rank because Spartan is your rank. You are naturally superior. We have made you better. You are Spartans now. Start acting like it.|[[Musa-096]]<ref name="HI2">'''Halo: Initiation''', ''[[Halo: Initiation Issue 2|Issue 2]]''</ref>}}

The '''SPARTAN-IV program''' is the fourth iteration of the [[SPARTAN programs|SPARTAN supersoldier projects]]. Like the original [[ORION Project]], the SPARTAN-IV program utilizes consenting adult volunteers selected from the other branches of the [[United Nations Space Command]], in contrast to the previous two programs which used children as candidates.<ref name="glass434">'''Halo: Glasslands''', ''page 434''</ref> Recruits are drawn from both career military veterans and young soldiers who show considerable promise.<ref name="EH">'''[[Eleventh Hour reports]]''', ''part 3''</ref>

The [[SPARTAN-IV Augmentation Program|physical augmentations]] of the Spartan-IV supersoldiers are more modest than those of the two preceding programs, although their standard-issue [[MJOLNIR Powered Assault Armor (GEN2)|GEN2 Mjolnir armor]] is designed to compensate for this drawback.<ref name="frankie">[http://members.shaw.ca/laird2/temp/derp/interview.mp3 '''Frank O'Connor interview during San Diego Comic-Con 2012'''] 1:15 - 2:10</ref><ref name="frankie"/><ref>[http://www.gameinformer.com/b/features/archive/2015/06/11/halo-5-guardians-unmasking-the-fireteam-hunting-master-chief.aspx '''Halo 5: Guardians – Unmasking The Fireteam Hunting Master Chief''']</ref> The Spartan-IVs serve in [[Spartan Operations]], an independent branch of the [[UNSC Armed Forces]] created for the oversight of their operations.<ref name="story">[http://halo.xbox.com/halo4#!an-epic-universe/story/6eeabce4-dc80-4aa3-b2aa-2f5d123b7514 '''Halo 4 Official Site:''' ''Story'']</ref>

==History==
[[File:HI_Spartans.png|thumb|left|300px|Some of the first Spartan-IVs aboard ''Infinity''.{{clear}} (l-r) [[Edward Davis|Davis]], [[Joel Thomas|Thomas]], [[Sarah Palmer|Palmer]], [[Vladimir Scruggs|Scruggs]], and [[Yeong-hao Holst|Holst]].]]
The SPARTAN-IV program has its roots in [[2550]], when ONI began to experiment with adding limited [[Biological augmentation|enhancements]] to select groups of special operators.<ref name="HOSFM87">'''[[Halo: Official Spartan Field Manual]]''', ''page 87''</ref> At some point prior to the instatement of the current SPARTAN-IV program in [[2552]], elements within the [[Office of Naval Intelligence#Section Three|Office of Naval Intelligence's Section III]] authorized a prototypical phase without approval from [[UNSC High Command|High Command]]. This incarnation was intended to produce supersoldiers whose physical prowess rendered [[MJOLNIR Powered Assault Armor|MJOLNIR armor]] redundant. However, only one of the ten volunteer test subjects survived the augmentation process. The survivor, [[Ilsa Zane]], was driven mad by the experience and was folded into ONI. Despite the project's failure, Zane was considered the original Spartan-IV.<ref name="HI3"/>

The program as it now exists was commissioned as a result of the success of the preceding [[SPARTAN-II program|SPARTAN-II]] and [[SPARTAN-III program|SPARTAN-III]] projects. The SPARTAN-IV project was conceived by [[Lieutenant Commander]] [[Musa-096]], a former Spartan-II candidate who was crippled by the [[SPARTAN-II augmentation procedures|augmentation process]]. Despite his grudge toward [[Catherine Halsey|Dr. Catherine Halsey]], Musa recognized the crucial role of the Spartans in defending humanity and the continued importance of the supersoldiers in the aftermath of the [[Human-Covenant War]].<ref name="HI1">'''[[Halo: Initiation]]''', ''[[Halo: Initiation Issue 1|Issue 1]]''</ref> The proposal was approved by [[Margaret Parangosky|Admiral Margaret Parangosky]], then-Commander-in-Chief of the Office of Naval Intelligence, and the new program was initiated under her orders. Parangosky initially planned to have SPARTAN-III lead [[Colonel]] [[James Ackerson]] heading the program, with SPARTAN-II project lead [[Catherine Halsey|Dr. Catherine Halsey]] to be reassigned as Ackerson's subordinate.<ref>'''Halo: Glasslands''', ''page 147''</ref> Ackerson was killed following the [[Battle of Mare Erythraeum]] and Halsey was arrested after returning from [[Onyx]], though ONI continued the program without the two,<ref name="infinity">'''Halo: Glasslands''', ''page 422''</ref> headed by Musa-096 and [[Jun-A266]], a former [[SPARTAN-III Alpha Company]] member.<ref name="HI1"/>

The first class of Spartan-IVs, consisting of 145 members, went active on [[2553#January|January 7, 2553]].<ref name="wp spartans">[https://www.halowaypoint.com/en-us/universe/factions/spartans '''Halo Waypoint''' - ''Spartans'']</ref> Due to the success of the initial group, Commander Musa-096 was able to secure funding for a second class. Initiated in [[2554]], the second class was considerably larger than the first one due to the increased funding and was able to draw from a wider pool of candidates.<ref>'''Halo: New Blood''', ''page 106'' (Google Play edition)</ref>

==Facilities and organization==
The SPARTAN-IV program is headquartered at a dedicated facility on [[Mars]]. Their [[SPARTAN-IV Augmentation Program|augmentation procedures]] are conducted at the same facility.<ref>'''Halo: New Blood''', ''pages 113, 126, 174'' (Google Play edition)</ref> The compound is able to augment around a dozen or two Spartans at any given time.<ref>'''Halo: New Blood''', ''page 115'' (Google Play edition)</ref> Their training is primarily conducted in a [[Spartan-IV Training Station|top-secret space station]] orbiting an unidentified dwarf planet.<ref>'''Halo: New Blood''', ''page 122'' (Google Play edition)</ref>

Hundreds of Spartan-IVs are assigned to {{UNSCShip|Infinity}}, the most powerful warship ever constructed by mankind.<ref name="infinity"/> The frigate {{UNSCShip|Meriwether Lewis}} also has its own Spartan contingent.<ref name="H5GLtd"/> Spartan-IVs train with one another in simulations known as "[[War Games]]" on ''Infinity''<nowiki/>'s state-of-the art combat deck (a training chamber that is capable of replicating environments), in order to constantly stay battle-ready.<ref name="gameinformer">'''Gameinformer''' (''May 2012''), ''pages 46-47''</ref> Spartan-IVs also train in multiple different forms of [[martial arts]] outside of the War Games simulator.<ref>[[:File:Spartan IV's sparring.png|Image showing Thorne, Madsen, and other Spartan-IVs sparring in different forms of MMA.]]</ref> As per [[STO 11.6]], Spartan daily training must include at least two hours of military occupational specialty training, and two hours of physical conditioning and augmentation monitoring. <ref name"LC">'''[[Halo Legendary Crate]]''', ''[[Halo Legendary Crate/Data Drops|Data Drop #1]]''</ref> Select Spartan-IIs have participated in the training of the Spartan-IVs.<ref name="wp spartan">[https://www.halowaypoint.com/en-us/universe/factions/spartans '''Halo Waypoint''': ''Spartans'']</ref>

The Spartan-IVs serve in a dedicated branch of the UNSC known as [[Spartan Operations]] or "Spartans", whereas their forebears operated within other chains of command,<ref name="story"/> although some Spartan-IVs serve in more covert roles within ONI.<ref name="wp spartans"/> In addition to the significant numbers of adult volunteers which make up the majority of the Spartan-IVs, the Spartan-IIIs who survived the [[Human-Covenant War]] were offered to be integrated with the Spartan-IVs in the new Spartan branch.<ref>'''Halo: Glasslands''', ''page 435''</ref> Many of the remaining Spartan-IIIs were folded in with the Spartan-IVs in the new branch, while others resigned to noncombat roles.<ref>[https://www.halowaypoint.com/en-us/forums/db05ce78845f4120b062c50816008e5d/topics/catalog-interaction/4c3e1c6f-6519-4ee0-83a4-4bac13bf07a3/posts?page=14 '''Halo Waypoint''': ''Catalog Interaction - Page 14'']</ref>

==Personnel==
Unlike their predecessors, the Spartan-IVs are identified by their surnames rather than numeric tags (due to their volunteered enlistment rather than conscription). The Spartan-IVs have shown a great deal of solidarity, especially impressive given the short time they have served together. Many of them have adopted colloquialisms first used by the Spartan-IIs, such as "Alpha Bravo" for "Alien Bastard". Psychologists assert that this camaraderie and cohesiveness will help distinguish the Spartan-IVs, and the Spartan branch as a whole, from the other UNSC branches.<ref name="EH"/>

==Equipment==
[[File:Majestic - 4.jpg|250px|thumb|[[Fireteam Majestic]] sporting variations of MJOLNIR [GEN2] armor.]]
===MJOLNIR armor===
{{Main|MJOLNIR Powered Assault Armor (GEN2)}}
Spartan-IVs are equipped with the MJOLNIR [GEN2], the second-generation version of the [[MJOLNIR Powered Assault Armor]].<ref name="gameinformer"/> Because of the Spartan-IVs' less extensive biological augmentations, the GEN2 armor boosts its wearer's reactions, speed, and strength to a greater degree than the first-generation Mjolnir.<ref name="frankie"/>

An assortment of armor configurations are available for all new Spartans per [[UNSC Regulation 3A-950]], and Spartans are capable of customizing their individual armor set with modular components from a wide range of special-purpose variants, based on their personal preferences, specialization and mission requirements. Selecting variants for purely cosmetic reasons is discouraged. It is strictly forbidden for Spartans to attempt to repair or modify their armor; all armor maintenance is only to be performed by qualified Class-61 technicians in dedicated facilities.<ref name="packet">'''[[Halo 4 Limited Edition]]''' - ''[[Infinity Briefing Packet]]''</ref> Unlike the generally green coloration of the Spartan-IIs' Mjolnir armor, Spartan-IV armor comes in a profusion of distinct color patterns, with the members of specific teams often sporting a consistent coloration.<ref name="spops"/> However, any customization of the armor color must be in accordance to [[UNSC Equipment Code 20.00.62]].<ref name="packet"/>

The standard-issue armor set for Spartan-IV (at least those assigned to {{UNSCShip|Infinity}}) is the [[MJOLNIR Powered Assault Armor/Recruit|Recruit]] variant,<ref>'''Halo 4''', ''Recruit armor description''</ref> colored gray and gold.<ref>'''Halo 4''' campaign level ''[[Infinity (level)|Infinity]]''</ref><ref name="spops">'''Spartan Ops'''</ref> Spartan-IVs also have access to more specialized equipment depending on their missions, example being the [[Infinity Actual Kit]], and [[Forerunner Hybrid Kit]].
{{Clear}}

===Augmentation procedures===
{{Main|SPARTAN-IV Augmentation Program}}
Like [[SPARTAN-II augmentation procedures|the augmentations]] performed for the [[SPARTAN-II program|Spartan-IIs]] and the [[Project CHRYSANTHEMUM|improved procedures]] utilized in the subsequent [[SPARTAN-III program]], the Spartan-IVs undergo a series of procedures to enhance their physical capabilities and to wear Mjolnir powered armor.<ref name="story"/> The technology used in the two preceding SPARTAN programs necessitated that the candidates meet exceedingly strict genetic qualifications as well as the application of the enhancements on preteens, to avoid the catastrophic failure rates produced by the augmentation of adult subjects in the [[ORION Project]].<ref>'''[[Dr. Halsey's personal journal]]'''</ref> By the time of the initiation of the SPARTAN-IV program, the technology had advanced to the point that adults could be augmented without major risk,<ref>'''Halo: New Blood''', ''page 52'' (Google Play edition)</ref> although the improvements to the subject's strength and speed are not as extensive as in the previous two programs.<ref name="frankie"/><ref>'''Halo: New Blood''', ''page 113'' (Google Play edition)</ref>
