{{Quote|Jump Feet First into Hell!|Official motto}}
The '''105th Shock Troops Division''', also known by the sobriquet "'''''Helljumpers'''''", is a formation of [[Orbital Drop Shock Troopers]] of the [[UNSC Marine Corps]]. It is highly regarded by many to be one of the best divisions in the [[UNSC Armed Forces]]. The division's insignia is a "Gold Comet".<ref>'''[[Halo Encyclopedia (2009 edition)]]''', ''page 59'' (2011)</ref>

==Background==
Members of the 105th possess 'exceptional' ''esprit de corps'' and immense pride and distinction in their unit, reflected by the customary comet-and-skull tattoo each received. Their motto, ''"Jump Feet First into Hell!"'', coupled with their employment of [[Single Occupant Exoatmospheric Insertion Vehicle]]s, has earned them the nickname "Helljumpers".

The 105th is infamous for its brutality, even toward fellow human troops. On one occasion, ODSTs from the 105th were involved in a fight with the fourteen-year-old [[SPARTAN-II program|Spartan]] [[John-117]], resulting in three ODST deaths and one severe injury.<ref>'''Halo: The Fall of Reach''', ''pages 65-67''</ref><ref name="HtF">'''Halo: The Flood'''</ref>

The 105th has a [[Helljumpers' anthem|distinct anthem]]. Helljumpers sometimes play this song during orbital drops to focus their attention and to calm their nerves.<ref>'''Halo: The Flood''', ''page 36''</ref>

==History==
The 105th was instated as early as [[2525]], with detachments of the Helljumpers being stationed on a number of ships, including the ''[[UNSC Atlas]]''.<ref name="TFoR">'''Halo: The Fall of Reach'''</ref>

The 105th were first deployed against the [[Covenant]] during the [[Battle of Hat Yai]] in late [[2528]] or early [[2529]]. Though the ODSTs sustained fairly light losses, [[Hat Yai|the planet]] was [[Glassing|glassed]].<ref name="Dirt">'''Halo: Evolutions - Essential Tales of the Halo Universe''', ''Dirt''</ref> Elements of the 105th later participated in the [[Battle of Arcadia]], and the [[Battle of the Etran Harborage]].<ref>'''Halo Wars'''</ref>{{Verify source}} In [[2535]], a small detachment of the 105th, assigned to the {{UNSCShip|Midsummer Night}} foiled a Covenant attempt to deceive the citizens of [[the Rubble]] during the [[Battle of Metisette]].<ref>'''Halo: The Cole Protocol'''</ref> In [[2547]], an element of the 105th Division took part in the [[Battle of Skopje]], defending a major ship construction firm from Covenant attack.{{Ref/Reuse|Dirt}}

At some point in the war, a squad from the 105th Division was sent on an assassination mission to assassinate a [[Unidentified Prophet (Heian)|logistics Prophet]] on [[Heian]], aided by Spartan [[Cal-141]].<ref>'''Halo Legends:''' ''The Babysitter''</ref>

In [[2552#January|January 2552]], a unit of the 105th was deployed to [[Ariel]] to enact [[Battle of Ariel|Operation: FIRESIDE]]. Ultimately, the Covenant were prevented from accessing [[the Knowing]], a [[Forerunner]] [[artificial intelligence]] beneath the colony.<ref>'''Halo: Helljumper'''</ref>

During the [[Fall of Reach]] in summer 2552, several elements of the 105th were deployed across the planet, though they were unable to stop the Covenant onslaught. In [[2552#September|September]], subordinate units of the 105th stationed on the {{UNSCShip|Pillar of Autumn}}, having survived the disaster at [[Reach]], fought in the [[Battle of Installation 04]]. These ODSTs were instrumental in frustrating Covenant attempts to purge the [[Installation 04|Halo]] of humans.{{Ref/Reuse|HtF}}<ref>'''Halo: Combat Evolved'''</ref> Later that month, 105th Division ODSTs attached to the [[26th Marine Expeditionary Force]] were almost completely annihilated during the [[Battle of New Jerusalem]].{{Ref/Reuse|Dirt}}<ref>'''Halo 3: ODST'''</ref>

Elements of the 105th Division's 7th Battalion were stationed on the {{UNSCShip|In Amber Clad}} and participated in the [[Battle of Earth]] and later the [[Battle of Installation 05]].<ref>'''Halo 2'''</ref> Another unit of the 105th, which was stationed on the {{UNSCShip|Forward Unto Dawn}}, participated in the [[Battle of Installation 00]], the last battle of the Human-Covenant War.<ref>'''Halo 3'''</ref>

==Subordinate units==
*[[2nd Shock Troops Battalion]]
*[[7th Shock Troops Battalion]]
**[[First Platoon (ODST)|First Platoon]]
*[[9th Shock Troops Battalion]]
**[[Boomerang Company]]
***[[First Platoon (Spirit of Fire)|First Platoon]]
*[[10th Shock Troops Battalion]]
*[[11th Shock Troops Battalion]]
*[[19th Shock Troops Battalion]]
*22nd Shock Troops Battalion

==Trivia==
*The 105th Division should not be confused with the [[105th Drop Jet Platoon]], which may have been similar to the ODSTs, albeit operating on a smaller scale.
*The number 105 is divisible by 7, possibly making it one of Bungie's many [[Seven|7]] references.
