105th Shock Troops Division

The 105th Orbital Drop Shock Trooper Division was regarded as the best ODST divisions in the UNSC Marine Corps.

Background
Members of the 105th possessed exceptional esprit de corps and immense pride in their unit, reflected by the customary tattoo each received. Their motto, "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-117, resulting in two ODST deaths.

History
The 105th was around as early as 2525. Detachments of the Marines have been on a number of ships, including the UNSC Atlas.
