Editing Life Bringers (section)

==Legion Organization==

Before the were reunited with their primarch, the Brothers of Death were known almost solely for vicious clearing actions against entrenched hostile forces, specifically hive clearing. The legion was no stranger to biochemical warfare before being reunited with their primarch, utilizing it as the preferred first-line tactic, but their tendency to follow up these actions with massed close infantry seemed an unacceptable risk to Johannes. Where they had previously strode alongside death, the legion would now bring life, and with it a change in strategy. No longer were the men of the XIIth expected to march unprotected into the hazard-zones they had created, they went from the among the most reckless legions to the most judicious when it came to the safety of its marines. Close-quarters combat was utilized only rarely and as a final resort, with squadrons expected to engage in long-distance heavy bombardment. Heavily equipped squads were fairly common, with dedicated artillery units being deployed early in campaigns to repeatedly shell cities and force their occupants into buildings, which would then be gassed. The same topic was often employed in reverse, forcing entrenched enemies out into the firing line. 

Under Johannes, each officer of the newly christened Life Bringers were taught in the ways of the medicine and biology. Sergeants were charged first with responsibility over the well-being of their men, this held paramount importance in the consideration of command roles. Dedicated apothecaries within the legion still existed, they are deployed to the areas of fiercest fighting in order to best perform their unique role on the battlefield. Gene-seed of the fallen was largely collected by the officers of a given squad, so dedicated apothecaries were free to unleash their myriad of terrible biochemical weapons on their enemies or tend to marines whose grave wounds would have ordinarily left them as casualties for the remainder of the battle. The most feared of their number are the Plague Masters, dedicated apothecaries with a talent for turning their craft to war.

The legion's favor for chemical weaponry increased drastically with their primarch's discovery, quickly going from a reliable tactic to outright dogma. Where the legion was once known for close assault, bombardment and ranged combat soon became the norm. At the first sign of a planet's resistance, marines are recalled and numerous low-air assaults and bombardments begin in an effort to remove any defenses. Once anti-air weapons have been crippled, the Life Bringers' fleet drops its terrible payload. Genetically engineered plagues and vitriolic chemicals are blasted into major population centers, whole forests are cleared, and what remains living is reduced to a sickly rendition of its former being. The robust marines then drop onto the poisoned soil below and meticulously eradicate all that lives, their superhuman immunity and equipment keeping them protected from the death which surrounds them. 

There were no better cultivators than the XIIth legion, they were as thorough in scouring worlds as they were at terraforming them. The new planets left behind by the Life Bringers were lush and fertile, and the engineered flora and fauna introduced by the legion were always hardier and more bountiful than those they replaced. A High Genetor assigned to the rebuilding of a world treated it as he pinnacle of his art, ensuring its ecosystem could thrive no matter the imbalances wrought upon it. The legion was beloved by those few populations who survived an encounter with it, diseases afflicting the population were cured and they were welcomed as brothers to the Imperium. Planets would be uplifted with generative technology similar to that used on the worlds the legion eradicated, ensuring a cornucopia for the loyal.   

The XIIth were often deployed alongside their brother legions during protracted or difficult campaigns where their talent for aiding the injured was of the most utility. Some of these legions saw the Life Bringers as a mere utility force, unable to do much alone, but those who fought alongside them knew they delivered death better than most. Most of the XIIth were well-liked by their fellows for their kindness and dedication to their fellows, and there are many tales of Life Bringers giving up their lives in an attempt to save those of their allies, while others saw their distaste for combat as suspect and their focus on healing was a needless detriment to the Imperium's advance. 

Following the Hektor Heresy, the Life Bringers tactics changed very little, they still rely on bombardments and ranged attacks to erase cohesive resistance. Life Bringers marines now have little to fear from being caught in the blast of a virus-bomb, so drop pods are launched alongside the biochemical strike. The bloated plague marines joyfully stride out amidst the toxic explosions, led by skeletal Plague Doctors carrying needleguns. Plague Masters joyously give the gifts of their latest experiments and genetic alterations to their foes, eagerly charting the effects of some new contagion as their enemies fall. The war with disease has been made into an unholy peace, and the formerly sober marines are now a twisted and joyous foil to what they once were.
