Killer Crocs have a reputation of being both honorable and very efficent and have a deep hatred towards slavery and always keep there contacts but been know for turning on there contacts after the job is done if they find out something they don't like. they were founded by formor Turian Military Rayn Katrina and Human mercenary Alex Nelson

Killer Crocs always work in teams which are may be led by more experialenced commandos. They often use Varren and Mechs to help support in battle. Killer Crocs in general seems to have very good Military training and ten to favor both Brutle strength and Intelligents and discrimination whitch makes them very dangerous in combat.

Prospective Killer Crocs operatives, at least on Tuckanka, are rumored to have to survive in the wild wastleland of Tuckanka for 5 days before they are given their uniform. This rumor turn out to be quite true in at least one case.

Killer Croc mercenaries can be identifled by Green or Gray armor featuring the Killer Croc logo, a head of a Croc baring his teeth on the chest in the center by a captital C.

Killer Croc mercenaries are bilty rivals with the Blue Suns and have been know for there battles with them arcoss the galaxy and always seem to

have a edge against them with Equipment and weaponry as well they have more numbers then they have and the military training

Wraith

Wraith is by far the most dangerous and best mercenary band there is in the galaxy. The Wraith have a reputation for being ruthlessly and honorable and feared across the galaxy and have been for hunting down slavers across the galaxy and are bilty enemies with Cerberus. They were founded by Ex Alliance N7 commando Brayan Miller.

Wraith Provide effective defenders for colonys across galaxy and do have scruples about the nature of those who hire them and will turn on them if they find some thing they don't like almost the the Killer Crocs do. Wraith mercenaries work in teams of vanguards and troopers and always have at least one experienced Soldier with them to make sure not thing gose wrong in the job. They often use Gunships to support in battle.

Wraith in general are very cunning and dangerous in battle and seem to favor stealth and intelligent brutle strength and gurweill(sorry i accented forgot the word) warfare. They are made up of Quarians Turians Krogans Human Asari Salarian and Drell and even Yagh how they keep them in control is unknown. They have a large number of Vanguards in their employ, and have good resources and have the best tech of all the merc bands. Wraith control nearly 50% of all Omega and the leader appears to have a good friendship with Aria and specialize in transporting goods to the Alliance and Citadel and hunting down Cerberus operatives across the galaxy.

Shadow Raiders

Oringinally a task force that of Aria's but left and was transformed into a mercenary legion by a Batarian pirate name Belek Artcis. leading the Shadow Raiders as a pirate group, Belek cultivated recuits and infamy for a year. Rumor has it you must go through the brutle training before you can call yourself a Shadow Raider and 50 out of a 100 make it through it. Thanks to his notoriety ensured his initial pupblic offering for his investors made Belek very much rich. Belek then stared rallying other Batarian pirate groups and Vorcha packs, and their firepower and support towards a professional violence in the Terminus Systerms.

Since they are banned from Citadel Space do there raids against there cargo ships. Shadow Raiders both bribes and kill it's throgh spaceports into armed confilicts across the galaxy. Priding themselves for accepting untouchable contracts, they have little thought on what the job is at longest the paid is good. Shadow Raiders appears to be, for the most part made of entirely of Vorcha Batarian and Turians members, though they also use Varren as war beasts much like the Blood Pack.

Seeing the potential of the vorcha's individual adaptability and the Turians Skills in combat, Shadow Raiders mercenaries and pirates often sweep through pockets of vorcha and always look out for turians looking for work and literally beating them into soldiers and born killers. Gaining even a few of them gives the mercenary and pirate band a formidable advantage; each additional vorcha make magnifies the band's combat ferocity exponentially much like the Blood Packs dose.

They can be identified by there Black and White armor with there logo on there shoulders a Skull and cross bones in flames

Shadow Raiders seem to have a rival with the Blood Pack, you will often find them fighting one other every time and do to there intelligent they often always win there battles with the Blood Pack

Inferno

The Inferno are a mercenary organization based on Citadel. They are both highly trained and organized, setting them apart from other gangs like the Blood Pack and Shadow Raiders, and they are more honorable then them and always keep there contracts. Founded by a Quarian Bounty Hunter name Zorcgh`Yurr the Inferno are the best option for formor Soldiers looking for work and gain footholds on the staion. They often help C Sec with crinimals and terrorist they earned respect in the Citadel and if you need protection there best ones to look for and often do it for free. The Inferno are strong enough to keep the streets safe from Crinimals and Terrorist they control stable and prevent riots.

The Inferno in general are most a infiltrator group and work in team of 5 and have never lost a men in a mission and often never leave one behind. They seem to have elitle military training and rumor has it that Zaeed had a play of training them to be elitle killers and they are made up of Quarian Drell Salarian Human Turian and Asari. even though there is only 200 members in the group this made no different to them and they often like to get up and personally to kill there targets.
