Editing Blood Jaguars (section)

== Chapter Organization ==
Though originally formed within the dictates of the ''Codex Astartes'', the Blood Jaguars were forced to revise their Chapter organisation and tactics during the events of The Long Night and the Coming of C'rtez in M35. Though the Chapter attempted to initially adhere to the ''Codex'', adjustments to the structure of the their companies were necessitated in order to fight against the upsurge of Chaos Cultists who utilized guerrilla and terror tactics in order to achieve their nefarious goals of mass destruction and death. Soon, the Blood Jaguars learned to adopt the use of such tactics and began to streamline their Chapter's organisational structure, with its echelons being biased in make-up towards line infantry formations. These formations became a hybrid of tactical/close assault troops for the main part, supported by dedicated scout squads and dedicated heavy assault units such as Terminators and specialized units of jump pack-equipped assault marines. This organisation lent itself well to a highly aggressive strategic posture and belligerent tactics, which while extremely costly in terms of casualties, are also highly effective. The rank structure of the Blood Jaguars remains simple and direct.

Each company is a self-sustaining entity, completely autonomous and quick to lend their aid to Imperial commanders across the galaxy, with or without the sanction of their Chapter Master. Despite some misgivings by their fellow Space Marine Chapters, this fluidity of command proves the presence of the Chapter's formidable discipline, not its absence. The Blood Jaguars maintain a high degree of flexibility in their deployments and structures, and in battle favor assault tactics over all else, however each battle-brother is fully expected to be proficient in Tactical, Assault and even Scout duties, as well as being skilled in the operation of all the Chapter's remaining vehicles. In theaters of war, individual squads are able to rapidly change their role to suit the mission and equipment on hand. In addition, the 1<sup>st</sup> Company has broken from the tradition of most Space Marine Chapters, as it is not a pure veteran force, as so few Blood Jaguars are able to withstand the pressure of the Black Rage long enough to gain such status. Instead, individual squads of Veteran Marines are formed within each company out of the most accomplished warriors they still possess.

=== ''Codex'' Divergence ===
Apothecaries are modified Sanguinary Priests, giving the blood of Sanguinius to Neophytes through a bloodletting ritual instead of by drinking. They favor obscuring masks and spend much time amongst themselves, their own little coven of priests.

Librarians also take on a religious role, leading many major services dedicated to the Sun Emperor (he who walks the darkest road shines brightest.) They decorate armor in midnight blue with solar designs, and are the most pious. Most of the Blood Jaguars respect them as some of the most important among their ranks.

The Centzon Tlaloc are the Blood Jaguar equivalent of the Sanguinary Guard found in the Blood Angel and their fellow Successor Chapters. They alone are allowed to wear the limited numbers of Terminator Armour the chapter has. They are known for their ardour and unwavering devotion, tasked with the ultimate safety of the Chapter Master. On rare occasions, they are also assigned as guards for other commanders as a sign of Xipet T'otec's favour.

The Tlīltik Ocelotl or 'Black Jaguars', are the Chapter's equivalent of the Blood Angels' infamous Death Company, which is not an actual part of the Blood Jaguars' standard organisation of ten companies. This company stands apart from the rest of the Chapter as a separate entity, and is made up of those battle-brothers who have completely succumbed to the psychosis of the Black Rage. These unstoppable and fanatical berserkers are led into battle by one of the Chapter's Tlamacazqui (Chaplains), who maintain a tenuous hold over this formation of psychotic killers. Every warrior in their ranks is a boon on the battlefield, possessed of righteous strength and holy fury. Armoured in black and gold, and marked by the symbolic wounds suffered by their fallen Primarch Sanguinius, the 'Black Jaguars' are a grim foreshadowing of the Blood Jaguars Chapter's final fate. Every warrior in their ranks is a boon on the battlefield, possessed of righteous strength and holy fury. Yet once the storm of war passes, madness and execution are all that await these tormented souls, driven past redemption by the curse in their tainted blood.

The Blood Jaguars maintain very few serfs, as the bulk of their failed aspirants either die during the Dark Road Under the Sun or are sacrificed (some even offering themselves in an attempt to make up for perceived sin.) Their Techmarines are also not terribly well-provisioned, and are very few in number, most of the chapter's weapons are heavily modified and very old. Many in the Mechanicus do not approve, and do not take many of their Battle-Brothers to Mars for training.

=== Special Weapons ===
The Blood Jaguars use modified versions of standard Astartes wargear, including:
*'''Macahuitl-Pattern Chainsword''' - The Blood Jaguars use modified versions of standard Astartes wargear. Instead of utilising the standard-issue Chainsword, the Astartes of this Chapter prefer to use Macahuitl-Pattern Chainswords, which have two sides (to avoid jamming) and use obsidian-tipped teeth. These weapons are brutally effective in melee, spraying gore in all directions, but lack some penetration power and may even shatter under extreme stress.

*'''Tenocit-Pattern Bolters''' - Tenocit-pattern bolters are also utilised by the Chapter in lieu of the standard Ryza and Tigrus patterns commonly used by most Space Marine Chapters, and are often decorated with the bones of local megafauna and religious pictographs.
