105th Shock Troops Division

The 105th Shock Troops Division (also known as the "Helljumpers") was a shock warfare formation of the UNSC Marine Corps. It's highly regarded by many to be one of the best divisions in the UNSC Defense Force.

Background
Members of the 105th possessed '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 Human Entry Vehicles, earned them the nickname of "Helljumpers".

The 105th was infamous for its brutality, even toward fellow human troops. On one occasion, ODSTs from the 105th were involved in a fight with SPARTAN John-117, resulting in three ODST deaths and one severe injury.

History
The 105th was around as early as 2525. Detachments of the Helljumpers have been stationed on a number of ships, including the UNSC Atlas. In 2552, subordinate units of the 105th were stationed on the and fought in the Battle of Installation 04. This unit was the 22nd Tactical, which was instrumental in frustrating Covenant attempts to purge the Halo of humans.

At some point in the war, a squad from the 105th Division was sent on an assassination mission to assassinate an unknown Prophet on Heian, aided by SPARTAN Cal-141.

Elements of the 7th Battalion were stationed on the and participated in the Battle of Earth and later the Battle of Installation 05. Another unit of the 105th which was stationed on the participated in the Battle of Installation 00.
