The immortals are a large faction, so certainly there are many sub groups refered to as branches within the faction, these branches all have their own name, and are normally recognized by their aproach towards combat situation and are oftenly only deployed on specific missions or only recieve very specific tasks.

The Bacteria
The Bacteria are known for their heavy armor and close range efficiency, they have earned their name for their tactics of boarding enemy ships, and much like real life diseases, disable the defenses of the enemy ships and ultimately killed them, due to their tactic their classes have been named after symptoms to reflect their aproach to enemy defenders.

-Asphyxiations, asphyxiations thank their name to the fact they use smoker rifles, they are the only bacteria using long range weaponry, mostly to deal with threats preemptively.

-Paralyzations, As the name suggests, paralyzations immobilize the enemy with the use of arc razors, bringing even the heaviest armored and thoughest enemies to a halt.

-Hearth attacks, Heart attacks wield close to medium range to end lives as fast as possible, just like the symptom they are named after they are fast in ending a life.

-External bleedings, external bleedings, as the name would suggest make use of explosive weapons to both deal with personnal and structural problems.

Pathfinders
Pathfinders are versatile troops that can be deployed in many situations, usually relying on stealth, agility, mobility or acuracy. The pathfinders oftenly wear light armor if not mere clothing. classes often rely on bows, sniper rifles or silenced close range weapons.

-Rangers, rangers are masters of the bow and crossbow. Their primary draw is their ability to retrieve their ammo if they are not using grizzly light series, wich is compact as well. They very much rely on stealth and complex gadgets to get the job done.

-Syiin rangers, Syiin rangers are and old tradition continued on today, the sun elves who were enslaves and then freed again in operation sunrise were quickly found ruthlessly effective with the use of grapple hooks to immobilize enemies and speed around the battlefield, the wood elves quickly adopted this style and added alchemy healing grenades to the equipment. Today the upgraded version forms the most lethal and complex addition to the pathfinders.

-Bladeslingers, Bladeslinging was an old light elven tradition, attaching heavy hatchets to chain to form a weapon that can be savagely swung and slashes around forming both a medium and short range meelee weapon, the bladeslingers heavily rely on stealth and agility to correctly make use of their weapons.

-Adventurers, adventurers are the heaviest addition to the pathfinders, wearing medium armor and wielding assault rifles or sniper rifles. Adventurers despite their armor and unsilenced weapons are best used as recon to bring an area into a map to help heavier attackers invade later, while still maintaining the ability to survive on the battlefield.

-Volunteers, Volunteers are well loved among any group as they posses the ability to heal, kill, support, escape and much more, they are often dispatched in hazardous areas or sent to patrol the fron line to give whatever support needed.

-Guides, guides are often tasked with leading troops through teritory, using the maps and intel the adventurers gathered. Guides often carry light equipment, generally the same as new generation scouts do.

-Jumpers, jumpers are equiped with exo suits to enhance their endurance, movement speed, jump height and overall agility, while some rangers utilize the same exo suit, jumpers are trained to make best use of them, oftenly they are deployed with no weapons, leaving them to rely on their speed and hand to hand power.

The New generation
The new generation was founded during operation eclipse tasked with freeing the sun elven slaves out of the renegade empire, they became a branch in the immortals when the faction officially went bankrupt and was bought over by the immortals, now they are once more allowed to do missions for their people under the flag of the immortals.

-Shadow walkers, another tradition of the elven race, shadow walkers are the pinnacle of stealth, there is no other race or army out there that could match the stealth abilities of shadow walkers, it is said that their marks never know they are going to die before they do pass out. Shadow walkers use modernized gadgets to remain invisible and hidden to scans while instead of regular weapons using a long silk scarf and an extremely long needle.

-Rogues, The new generation rogues are generally known for being extremely versatile, while their focus lays heavily on stealth, they are equiped with small shields and medium armor, allowing them to fight alongside more combat focused classes as well, generally rogues are deployed to infiltrate enemy fortress as they posses a camo ability and an EMP for alarms. In addition they ten to carry one weapon for stealth and one for combat.

-Snipers, the name itself says enough, snipers are tasked with assassinating high profile and then escaping, usually with the use of a lifeline, they are much like the syiin rangers equiped with grappling hooks though these are not ment for combat use, instead they should be kept for reaching vantage points and escaping.

-Scouts, new generation scouts are the attack hounds of the new generation, boasting highly powerfull close range weapons and medium armor to match. They are the line between spies and rogues often staying hidden inside or just outside enemy bases, collecting intel by eavesdropping or theft.

-Spies, as the name suggests, spies are the class in the new generation that oftenly apears to be allied to an enemy team, very oftenly spies are simply bribed by the immortals but sometimes they are delibiratly made to join the enemy to help gather intel.

The Royal Knights
Since the medievals, heroes with shields have always existed, and since it would be a crime to let this combat style die off, so new shields, swords and guns for them to wield, there are many classes in the knights but all of them wield shields.

-Defenders, as the name would suggest, defenders make very prominenet use of their shield barriers to defend their allies from incoming gunfire, while for now this shield is breakable it is still potent in defending other combatantsfrom gunfire, with their shields being so big it is hard to aim, instead they are equiped with meelee weapons like axes to slash at nearby enemies that got past the shields.

-Knights, Knights are heavily armored juggernauts, being able to ressist heavy damage. Much like the bacteria they are oftenly used in positions that require tanking damage, though much like the defenders they use meelee weapons more than guns, though knights are more offensive than defenders and slightly less resilient than the defenders.

-Enforcers, enforcers rely on their shield much more than other Royal knights, as they are not as their armor being only slightly thicker than normal heavy, while this will soak up damage, they are vulnerable to succumbing to armor piercing attacks if they get flanks, however, their shields are almost undestructable and allow for using pistols and smgs and for the skilled even assault rifles and shotguns.

-Royal rangers, the lightest addition to the royal branch of the immortals, royal rangers use medium armor, built in jet thrusters, teleporters and grappling hooks to reach high speeds, while their shield is alot smaller than those of the knight of the defender, it still has to ability to block an entire clip of most weapons, the royal rangers often wield either shotguns, smg's or daggers.

The Lovers
the deceptively named lovers are the primary healers of the immortals, they oftenly offer little to no assistance in combat and tend to focus on helping their allies escape or back in the fight, their deceptive name masks the fact that alot of their effective healing techniques are quite painfull, though effective.

-Healing rangers, as the name suggests, the healing rangers are fact paced healers that fly around the battlefield providing support to their allies with their alchemy grenades, usually equiped with weapons as well.

-Nymph's, the Nymph healing unit are usualy fairies, light elves or at least magically adept to become a nymph class healer their methods dont hurt either unlike that of the healing rangers or the other lovers in general. though it is alot slower as they require to give a constant stream of magic.

The Guardians (also known as the quarterbacks)
the guardians are the anti flanking branch of the immortals, in the guardians people are trained with short range and sometimes even meelee weapons like axes and hammers. Similar to the knights, though instead of protecting the team from frontal attacks, they defend the team from flanking attacks.

-Coastal guards, former coastal guards of dracholm now adapted to serve the immortals. formerly using normal hammers now adapted to use more modern adaptations of their former heavy weapons (i.e their normal hammer evolved into a rocket hammer, spears became miniguns etc.). Coastal guards are generally known for extreme endurance without using armor too.

The Security
as the name suggests the security branch is tasked with ensuring the safety of bases, they posses a wide variety of classes. the security is the decoy for police forces on apex 122 and imm'enne as the dracholmian government does not control these but the immortals do, in addition, the security also takes the task of military police, bouncing, law enforcement and the arrestation of criminals.

-Droids, the only class in the security as the law enforcement is fully mechanized.

Land raiders
The armored vehicle division within the immortals, this branch does not work with classes but with vehicle types instead.

-Artillery, Long range explosive vehicles designed to rain death down from afar.

-Armored assault, drivers typically found operating tanks, apc's and other heavily armored vehicles. They are usually found on the frontline laying down suppressing fire and using their heavily armored vehicles to provide cover to infantry.

The Airforce
Those flying vehicles in both space and above a planet are with the immortal airforce, tasked with raining death from above and defending our ships from other ships.

-Fighter pilots, The most praised class in the immortals are the fighter pilots for their performances in the sky and in space, using their daring and speed to keep the skies clear of hostiles.

-Captains, The drivers of large spaceships are aptly titled captains, their ships are treated more like boats then planes even if they are technically aircraft.
