Editing Behemoth Guard (section)

==Legion Organization==
The Legion is separated into Houses based upon the Houses they are recruited from, each with their own unique culture. Naturally, this causes brotherly rivalry between the houses that can cause trouble and politicking based upon the houses history. Each House is lead by a First, usually the best, or smartest individual of that House.

Grand Companies (Houses?)

IXth Grand Company 'The Brothers in Red'
These are the warpsmiths, the binders of daemons, the ones who experiment with daemon-flesh grafts and field the mind-scaring abomination engines.

They operate under Forge-Tyrant Kalvas Toevah and in his portfolio militant are forces such as rune-bound daemonic hosts, the name of each daemon scribed in human blood in his grimoires, allowing the IXth to summon daemons at a moment's notice.

The IXth is also responsible for the abomination engines, physically impossible machines built from warpstuff, their steel quenched in human blood and daemon ichor. Their workings make use of impossible geometries and often feature the stylized metal-worked forms of beasts melding seamlessly into the gears and pistons of some incomprehensible mechanism. A common motif are wheels within wheels.
When the IXth attacks, their daemonic slaves are unleashed. Survivors are fed to daemons, either bodily or in soul.
The abomination engines crash across the battlefield, amid hordes of daemons and cultists, followed by their marine masters.

XXIIth Grand Company 'The Dreamers in the Deep'
Lead by Mengthes Kraal, these guys are the Silica Animus and Daemon Engine boys. Where dudes like the IXth craft the aether into their baleful engines, the Dreamers in the Deep bind daemons to enhance their already potent mechnical creations.
They make heavy use of forge-slaves who have disappointed in their human wave attacks, which are really only there to draw attention away from the prized creations of the company.
These include legions of battle automatons, possessed by daemons, their weapons wreathed in warpflame, as well as armored vehicles augmented by daemonic influence. Amongst their most treasured creations are the massive land-crawlers, titan sized battle tanks, festooned with gargoyles belching warp-fire, with ectoplasmic cannons and are fueled by human souls.

IIIrd Grand Company 'The Pale Forge'
These guys are out to prove that even without the warp, they can be just as fucked up as their brethren. And, to the horror of everyone, they succeed.
They field bio-engineered plagues, or mount powerful sonic weaponry on tanks to liquefy enemy foot soldiers.
They also field crazed prisoners and slaves, partially lobotomized with electrowhips in place of hands and fueled by stimulants, but left aware of just what has happened to them.
At other times, they herd degenerates from cannibalistic sub-hive-sumps and unleash them in civilian populated areas.
They also make extensive use of the sort of strange technologies from Old Night or xenotech sources.
They're more like the Black Judges or the other more or less human opponents that the crusade toppled, as opposed to much of the rest of the legion, who sits around figuring out ways to weaponize children's screams.

===Recruitment and Initiation===
I'm not quite sure what they do with neophytes. Probably deal with them the way the Templars do--throw them in the squad. Recon is likely done through daemon oracles and scrying as opposed to traditional humint.
They do, however have fast out rider squads, in what amount to Salamanders and Bikes. I think they probably throw neophytes in here as a good way to learn on the go with some more experienced guys.
I think the legion ethos is decently friendly, if that makes any sense. Gengrat is a cold sociopath, but he loves his sons, takes pride in their accomplishments, they're as much his creations as are the abomination engines. The legion follows in suit.
Competition to be The First of a house or a Forge Tyrant is fierce, but in general, it's like Ferengi competition--cut throat, but not personal.
I think there is also an extent to which mentor and apprentice do not directly compete and if the apprentice does something great, it is to the glory of the mentor.
They're the Tzneetch legion, after all, and I think they deal with the plans and progress by enjoying the great game, the same way they genuinely enjoy weaponizing screams and tears.

Anyways, scouts and neophytes. Probably start off on a fast out rider rig. To be First of one of these is a big deal, too, since you get to train the neophytes.
Typically these are things like Salamander Squadrons, stripped down rhinos, or bikes. Anything fast. Particularly renowned ones may even have some Cybernetica hounds like vorax.
After a stint in one of the vehicle squadrons, the neophyte is sent someplace else based on what they prove adept at. Some work making bikes and become bikers, others join a heavier vehicle squadron, etc.
From there they're further specialized based on skills, with the big division being between the forge and the riders. Everyone does some sort of forge work, but after a stint in one of the main assault brigades, talented technoccultists are taken for further training, while the rest pursue different modes of Armored warfare, be it breaching and close assault or heavy weapons use.
