All the icons of the Support Upgrades.

Support upgrades are gameplay enhancements featured in Halo 4.^[1]

Overview

Support upgrades are armor mods for the MJOLNIR [GEN2] armor that enhance a Spartan's combat performance in the field. They can be accessed through each loadout before a match is started or during a player's respawn time. While some support upgrades are available since the beginning of the game, others are unlocked via Specializations.

List of upgrades

Ammo: overrides the armour's capacity and safety protocols of the GEN2 armor, allowing a Spartan to exceed normal ammunition-carrying parameters. The upgrade is recommended for CQB roles and encounters which require excessive ammo usage.^[1]
Awareness: facilitates minor adjustments in the MJOLNIR's HUD-distributed display mechanics, allowing the integration of a motion sensor into scoped weapon, native of exotic, smart-links. Thus, it provides a Spartan with basic motion sensor data while sighting an enemy. This upgrade is often relied upon by Spartans who engage in sniper operations or long-range combat.^[1]
Dexterity: circumvents overlock and mobility systems, temporarily allowing the bypass of fine-control movement governors to obtain quicker reloading times and weapon swapping. Upgrades which enhance movement have increased in popularity for operations with intense close quarters firefights which demand swift weapon versatility. ^[1]
Drop Recon: feeds the user information on the time and place of ordnance prior their drops occurring, thanks to suborbital, drone-linked monitoring systems which are embedded in the user's MJOLNIR support suit.^[1]
Explosives: manipulates energy placement differential systems which allows armour software to automatically transfer conclusive force from explosions sustained during combat. When used with MJOLNIR GEN2, it passively disperse receiving energy, allowing them to take less damage while increasing damage for targets.^[1]
Gunner: improves a variety of elements which favor heavy weapon specialists. This is allowed by software improvements in the suit's automated weapon communication nodes. The results include an increase in speed and mobility of a user carrying a detached turret and increasing the amount of time a Spartan can sustain fire before the weapon overheats.^[1]
Nemesis: marks the location of the hostile who last killed the user on the HUD. It is obviously impractical in real operations and is exclusive to War Games simulations. It does, however, increase tension for targeted participants. It is a balance-mitigation module.^[1]
Ordnance Priority: allows access to a Class-D4803 priority channel with UNSC infinity, due to a software patch which allows dialing couplers and satellite linkage. This allows users to call in ordnance more often. The upgrade is often utilized by Spartans during requisition-dense, support heavy combat in situations where the deployment of ordnance can be intermittent and scarce.^[1]
Recharge: decreases the time it takes for your shields to recharge.^[2]
Sensor: increases the range and sensitivity of the motion sensor. The upgrade violates general UNSC transmission regulations. It is utilized by stealth operatives and infiltration specialists to provide heightened locational intelligence of all nearby enemies.^[1]
Stability: increases aiming stability when being fired upon by alternating the suit's default kinetic dampeners. Overall it makes the user flinch less when under fire thus allowing a steady aim on target. Spartans, who participate in lateral combat maneuvers through environments which are notably dense with weapon, favor this upgrade.^[1]
Stealth: decreases user movement noise and visibility on certain enemy VISR enhancement systems such as Promethean vision and also increases lethality in assassinations. The software changes are largely nominal with this upgrade.^[1]
Survivor: if the vehicle is about to explode, anyone using the armor mod will be kicked out of the vehicle.^[2]

Trivia

The Recharge and Survivor upgrades were both added via title update in August 2013. As such they are not available in Spartan Ops. If a player has one of them equipped in their loadout, it will automatically revert back to "None".
