The Field Operations Guide FM 90-10-140 is a document printed for the use of the Office of Naval Intelligence that contains information on various ODST ordnance such as weapons, armor, as well as other field information.[1]

Sections of the manual[edit]

ONI Transmission[edit]

This section is a snippet of conversation between Captain Veronica Dare and an unidentified party requesting the co-opt of Alpha-Nine from their original mission.

 >> SENT: [DARE.V.500341(S1)]
 << Make it quick, Captain. You’re not the only bee buzzing in my hive today.
 >> Of course, sir. There’s a priority asset inside the city. We need to pull it out.
 << Can you be more specific?
 >> Sending you my report with relevant imagery now…
 << I’ll be damned… Either the Covenant’s getting sloppy or we’re getting lucky.
 >> Let’s hope a little of both.
 << This intel didn’t come from your shop?
 >> No, sir. From the city’s public security cameras.
 << Verification?
 >> HUMINT. Single source.
 << And?
 >> He checks out. Endesha, zero-zero-six-one-eight-two.
 << Municipal engineer… New Mombasa public works department… What’s he
doing in the basement of an S2 alpha-site?
 >> Damage control, apparently. He manages the Superintendent.
 << The same machine that registered this… seismic anomaly?
 >> Yes, sir
 << So what do you need, Captain?
 >> An extraction team. If you look at—
 << ODSTs? Negative. Admiral would have my ass if he knew I was pulling boots off
the line.
 >> Sir, with respect. The clock is ticking. We have an at-risk, Superintendent-class
A.I. packed with high-value data. And those troopers are racked and ready.
 << But Helljumpers? Really? Don’t you think this particular extraction requires a
little more… restraint?
 >> I can personally vouch for the capabilities of the gunnery sergeant and his
 << Personally? Buzz-buzz, Captain Dare.
 >> One squad. That’s all I need. And I’ll have the asset secured by sundown.
 << Very well, Captain. Get it done. Just one more thing…
 >> Sir?
 << The less your team knows about what they’re after the better.
 >> Like you said, sir—restraint.

Orbital Drop Shock Troopers[edit]

This page gives info about the ODSTs and their basic tools.

Orbital Drop Shock Troopers
Congratulations, trooper. As an ODST recruit, you are part of an elite, voluntary branch of the United Nations Space Command (UNSC) Marine Corps. Classified as special forces, ODSTs have earned the nickname “Helljumpers” because of our preferred deployment system: single-occupant, exoatmospheric insertion vehicles (SOEIVs)—drop pods fired from Navy ships unable to maintain safe orbit above Covenant-occupied worlds. SOEIVs are fully automated, but most ODSTs prefer to fly them manually, performing evasive maneuvers to evade hostile fire. Be advised: A typical drop terminates in a rapid deceleration 50 meters or less from the ground. And while SOEIVs are rugged systems, their thrusters and air-brakes have been known to fail, killing the occupant on impact. We call this “digging your own grave.” Because of the SOEIV’s cramped quarters, you will almost always deploy with lean gear. But there are two weapons no ODST would ever jump without:
M7S Submachine Gun
A sound-suppressed variant of the M7 rifle. Compact size, 48-round magazine, and 2x zoom reflex sight, make the M7S invaluable in stealthy urban operations.
M6S Magnum
A sound-suppressed variant of the M6 sidearm. With 4x zoom, 12-round magazine, and minimal recoil, the M6S excels at quick, precision kills.

Your ODST uniform and body armor are similar to those of a standard UNSC Marine except you are also equipped with a full-head helmet that, in addition to offering improved protection from ballistic and energy projectiles, carries a sophisticated, tactical heads-up display (HUD). The HUD not only shows your current loadout of grenades, weapons, and ammunition, it also provides real-time monitoring of your two most important biometrics: stamina and base body health. While the method of calculating these metrics is classified, your HUD makes them easy to understand: reddening around the edges of the HUD means your stamina is low; reduction of a narrow bar near the top of the HUD means your base health is depleted. Stamina recovers automatically as long as you are not taking hostile fire; but base health only improves with medical intervention via combat aid kits, or “medkits” for short. Fortunately, you have been trained in the use of civilian medkits—essential knowledge in urban terrain far from expeditionary medical facilities and Navy corpsmen.

While your HUD is designed for efficient, peripheral observation, new ODST recruits are encouraged to actively monitor their biometrics and adjust their fighting style accordingly.

ODST HUD and VISR[edit]

This section gives an in-depth look at the game HUD and VISR.

In addition to the HUD, an ODST’s helmet is equipped with the sophisticated Visual Intelligence System Reconnaissance Class—or VISR. The VISR is two useful technologies in one: a low-light, target-acquisition vision mode and a HUD-space database (see pages 8–9).

Please study the following key elements of your HUD and VISR before your first battlefield deployment.
Displays your current heading, navigation makers, and beacons (see callout 1 on page 8 for additional details).
VISR highlights friendly contacts green. Check your fire!
VISR outlines all hostile units and vehicles red.
Grenade Inventory
Press LB to cycle through grenades. Pull LT to throw the selected grenade.
Medkits, Weapons, Vehicles
OPTICAN medkits and abandoned weapons and vehicles are highlighted blue. To use a medkit, simply walk over or touch it. Hold RB to pick up a weapon or to drive a vehicle when you are standing near the driver seat.
Weapons and Ammunition
Displays available weapons (active weapon on top) and ammunition. Press Y to swap weapons.
Data Terminals
Data terminals appear yellow in VISR. Press RB to access a terminal and download all audio and visual data to your VISR database.
