Orbital Drop Shock Troopers

-ODST motto

The Orbital Drop Shock Troopers (ODSTs), colloquially known as Helljumpers are an UNSC Marine Corps Special Forces unit.

Origins
The Orbital Drop Shock Troopers have their roots in the paratroopers of 20th and 21st Century fame, who dropped frequently behind enemy lines to capture buildings, bridges, and other important military and industrial targets in anticipation for a larger advance by more conventional military forces. However, the origin of dropping humans from orbit comes from the Martian Campaign of 2163, where Marines were dropped onto Mars in support of UN forces against the Neo-Communist Koslovics.

Human-Covenant War
ODSTs were operating as early as 2525. The first division of ODST's were the 105th Orbital Drop Shock Trooper Division, which quickly gained a reputation as a brutal but effective fighting force.

Barring the personnel of the SPARTAN programs, ODSTs are one of the most effective forms of troops available to the UNSC, and the expectations placed on ODST units made them all-volunteer outfits, with some outsiders regarding such volunteers as 'crazy'. By 2552 their strength had swelled to a larger number of divisions in an attempt to fill the demands of the Human-Covenant War. Some ODSTs actively participated in training the SPARTAN-IIs, but the efficiency of that program was demonstrated when a single SPARTAN-II killed three ODSTs during an exercise. These fatalities resulted in ODST's having a disdain of the SPARTANS, as they were "Freaks" and not even worthy of being Human.

Operations
ODSTs are known for thier unorthodox methods of insertion, including orbital drops onto terrestrial targets.

Similar to regular Marines, the ODSTs maintain units of varying strength aboard many UNSC vessels and installations. ODST units were present aboard the, the , the , the , and Cairo Station.

While they are human, they are, overall, very different from marines in the sense that they take the most dangerous, crazy, and suicidal missions. They have no physical differences between the Marines, but they are always ready to "Jump feet first into hell" as their motto goes (this motto comes from the intense heat inside the HEV drop pods. The heat inside these pods is what coined the nickname 'Hell Jumpers' .), and dive into fights they may not return from, which shows an outstanding level of courage, honor, valor and sometimes insanity.

They also drop into areas that are under heavy assault, or are heavily guarded by enemy troops. This is because these areas are too dangerous for Pelican drop ships to land or drop reinforcements. They are also assigned to tasks such as landing and clearing a landing zone for reinforcements. An example of this is on Delta Halo, during the events of Halo 2. The ODSTs, accompanied by the Master Chief, must clear a landing zone so that Pelicans could drop off a Warthog.

Equipment
The Orbital Drop Shock Troopers use advanced equipment, specifically made for their purpose and missions.

Body Suit

 * Main Article: Body Suit



The ODST's, in addition to using normal Marine equipment, use a specially made body suit. It is completely black and sealed off, allowing for extra-vehicular operations. It has heating and cooling systems to mask the infrared signiture of the wearer, and it also has a oxygen tank capable of allowing 15 minutes in space. The helmet contains state of the art communications gear, along with a HUD and thermal and motion detectors.

During the Battle of the Ark, the ODST's appear to have colors on their shoulder armor which may denote ranking. There were 3-4 "whites" along with one "red," possibly meaning a red patch stands for Squad Leader, while white would be more akin to a Squad Member, this is very likely due to the fact that he is far more aggressive than the other ODST's and that he also often leads his teammates into combat. A white patch with a red cross symbolizes a squad medic. (It also bears noticing that in cut scenes showing ODSTs, their shoulder armor does not show any color and just appear black. This is, however, due to how the cinematics were designed for the game.)

Human Entry Vehicles

 * Main Article: Human Entry Vehicle



The Human Entry Vehicle (HEV) is a tear-drop shaped pod made of Titanium-A, Lead Foil, and a ceramic skin. They are known for their risky use, as many die either from the intense heat on re-entry, the extreme G-forces, or the force of hitting a terrestrial target. This is the main reason why many consider the ODSTs to be "insane".

The HEV also carries weapons, ammunition, food, a radio, and a cubicle for shelter in case the ODST is ever dropped off target or they need to fight immedately when they hit the ground.

Notable Actions
ODSTs were on board the Pillar of Autumn upon the discovery of Alpha Halo. An ODST group led by Major Antonio Silva was later instrumental in frustrating Covenant attempts to purge the ring-world of the Pillar of Autumn's survivors

Members of the 7th Orbital Drop Shock Trooper Battalion would go into the Outskirts of New Mombasa in support of the capture of the Prophet of Regret. They were in a separate Pelican fired upon by a Scarab. They fought through the outskirts before linking up to the main UNSC advance. Thier battle is showcased in the bonus video: Another Day at the Beach.

Members of the 7th Orbital Drop Shock Trooper Battalion would later drop from In Amber Clad onto Delta Halo. They then cleared a landing zone so that a Warthog could be deployed for John-117. Later, they were dropped from the to assist John-117 again, during the Battle of Installation 00 near the Ark and the Citadel.

Two ODSTs fought in the Battle of Pawas in 2552. Bravo-21 and Bravo-22, were tasked with calculating the crash site of the Master Chief on Earth, while a Marine Battalion was tasked with defending a narrow corridor between Covenant and UNSC forces in Pakistan. Bravo-21 and numerous Marines were killed in the fighting, while Bravo-22 was injured along with the other marine survivors.

Trivia

 * On the right side of an ODST's body armor is a Chinese character which when translated, means roughly complete Bad Ass, a reference to the ODST's hardcore attitude. Next to the character is a picture of the moon, or maybe an egg. Put these symbols together spells the Chinese word "混蛋", also means "Bad ass" or "Bastard".
 * The colored shoulder pauldrons are somewhat similar to the pauldron's on Imperial Stormtroopers in the Star Wars universe such as red/orange indicating leader while white indicates a private.
 * You always fight with members from the 7th battalion in the games.
 * ODSTs can also be deployed in Long Range HEVs from long distances away from the planet.
 * Onboard the UNSC Carrier Atlas, Spartan-117 had a confrontational moment with four ODSTs in the ship's gym. John had removed a pin from the weights at the bench press, and forgot to put it back. The ODSTs walked into the gym and went straight to the bench press. The weights fell and almost crushed one of the soldier's foot. A fight ensued and John killed two of the ODSTs and severely injured the others. Ever since then, relations between the Spartans and the ODSTs have been uneasy.  This does not seem to stop them from working to their utmost efficiency during the Battle of the Ark.
 * On the level Delta Halo, several dead ODSTs can be found. How to find them is in the easter egg Lost ODSTs.
 * There is an ODST helment Armor permutation in multiplayer that is unlocked by gaining enough experience to be a Spartan Recruit.
 * Several ODSTs from Halo 2 are found in High Charity in Halo 3 during the level Cortana. One is found with a flame thrower.
