[This chapter was inspired by Bismark's Blood and Iron speech as well as the imagery of the late 19th century and very early 20th century.]
Iron Sons
Origins It is unknown, but it is assumed to be an early founding due to their equipment and several traditions based around Mk6 armor and their own chapter legends. Based on existing evidence, the Iron Sons are assumed to be successor chapter of the Iron Hands. Their recruits are drawn from the hive world, Aglaea Prime. And the Iron Sons were founded to deal with the chaos after the Horus Heresy.
[i always like "unknown" as its lets you get away with a Second Founding chapter without being called on it. However, since there are now more Second Founding chapters than previously known, I guess this isn't such a big deal anymore. I feel that the early foundings should be reserved for us RT oldbies. ;) Moving on...]

Homeworld According to their own chapter legends, their original chapter name was the Iron Sons of Terra and their initial recruitment was taken from Terra. However, that was not to last long. Due to political conflicts with other space marine chapters , the Iron Sons along with several hundred thousand colonists traveled to and settled the world of Aglaea Prime. Their chapter name was then shortened to the Iron Sons. Aglaea Prime is one of seven planets in the XX system in the Segmentum Tempestus. While it is the only human habitable planet in the system, it is classified as a temperate deathworld.
Almost every humans on Aglaea Prime resides in one of several large hive cities which are islands of iron in a sea of green, but very dangerous, forests. In addition to its lush vegetation and biological resources, the planet possesses a wealth of mineral resources and was the main reason for original human settlement. However, each mine and expedition must be paid for in blood and iron from the forests and the forests are always quick to take back what is not defended. (Other planets in the system are also mineral rich and are mined in turn. They have their own risks mainly due to harmful atmospheres or no atmospheres at all.)
The hive cities are not safe shelters though. In addition to the dangers of gang warfare, industrial accidents, political unrest, etc. that hive cities of Aglaea Prime share with hive cities on other imperial worlds, the flora and fauna of death world always seek to breach openings in the lower levels of the cities. Not surprisingly, it is the lower classes that face the most risks from these incursions and often find themselves fighting for their lives. It is from these individuals that the Iron Sons draw their recruits as well as from the other ranks of society that take up the mantle to defend their cities.
Theatre of Operations
While the Iron Sons have a homeworld, they can be found almost anywhere in Segmentum Tempestus fighting xenos in which they specialize.
Hall of Warriors
Deep within their chapter monastery, there is a artifact called the Hall of Warriors that is rumored to be from the Dark Age of Technology. It is an artifact that the Iron Sons bought with them from Terra when the world was first settled. It is hall of containing almost two dozen thick walled pods. These pods are capable of rapidly neuro-training a person that is placed within one. Currently, the artifact is programmed to train subjects in military combat. Techmarines and techpriests from the Adeptus Mechanicus are no longer capable of changing its programming or copying the artifact. In fact, they can barely maintain the artifact as it is. In its current state, it either kills or mentally cripples 50% to 90% of the initiates that use it. Fortunately, the hive cities of Aglaea Prime provide them a large pool of new recruits.
While some viewed the artifact as technology akin to the Iron Men and that it should be destroyed, others viewed the virtual trainers within the artifact as the souls of eternal warriors who will train those that prove themselves worthy to them. The artifact is the most treasured object of the Iron Sons and they will go to any lengths to prevent any damage to it or to keep it from falling into the hands of anyone else.
While undergoing the trial within the hall, being addressed by the eternal warrior, Ree E'mey, is one of the greatest honors that a new initiates can experience. Training trials where no recruits die are very rare and are taken as good omens. To date, this has happened only twice in the chapter's history.
The few Initiates that survive the chamber, but are mentally crippled, are absorbed into the chapter as servitors. They are respected as those whose souls were captured by the artifact to serve the eternal warriors and the chapter for all time.
The artifact was a gift from the Adeptus Mechanicus back when the chapter was still being founded. It may have been a ploy by the techpriests to gain subtle control over a marine chapter. However that plan, like the artifact itself, did not quite work as intended. As noted, the artifact is incredibly dangerous and it operates on a rather small scale which makes it suitable for the post-Heresy Adeptus Astartes. The Adeptus Mechanicus felt it would be best used by the cooperative chapter of the Adeptus Astartes and the Iron Sons just happened to be suitable subjects at the right time in the right place. As the centuries have passed, it is quite likely that the Adeptus Mechanicus have long since forgotten about their gift.
Organization
While the Hall of Warriors can greatly accelerate combat training and is good for teaching core military concepts, it has its limits as some of the fighting styles are very archaic, e.g. fighting without body armor, using autoguns, etc.
As a result, Iron Sons do not use scout squads as the Hall of Warriors can train their recruits past that point. They do not see the point of training new marines in fighting styles they will just discard in the long run. Plus, losses among scout squads would just be too great especially when combined with the losses from the Hall of Warriors. The tenth company is still the initiate company but they are used for non-frontline duties. The lack of scouts can hamper them somewhat, but they tend to focus on missions where subtlety is not required.
Beliefs
Due to the Hall of Warriors and the act of genetic and surgical treatment to create a space marine, the Iron Sons consider this a "second" birth. The first birth was of blood; the second, of iron.
Due to close relationship to the Adeptus Mechanicus at their founding and possibly their descent from the Iron Hands, they have a fascination with technology and cybernetics, but not to the extent of the Iron Hands. They also do not share the Iron Fist's obsession over the death of their primarch. In fact there was once open conflict between the Iron Sons and their parent chapter when a Iron Son commander made a remark that had the primarch been thinking logically, he wouldn't have gotten himself killed.
Chapter brothers also tend to use very archaic terminology and phrases that they have picked up from the chamber. This neuro-training also reinforces a common set of beliefs and values that all members of the chapter share.
When an initiate enters the Chamber of Warriors, they prepare themselves to face the eternal warriors that dwell within the artifact. If the initiate is accepted, i.e. they survive the neuro-training process; they become chapter brothers at that point and begin the rest of their training with current equipment, armor and weapons used by the chapter.
Fighting Style
They focus on blitzkrieg style warfare. Their small numbers are a disadvantage in prolonged combat. And this is the style of combat that the ancient instructors from the Hall of Warriors have taught them.
Battle History The Battle of Basham III which was one of their first battles that was almost a disaster. A rebellion had spread across four worlds in the Basham system and was threatening to spread to other systems. Four companies of the Iron Sons along with elements of an imperial army were sent to deal with the rebellion. Upon arrival in the system, one company of the Iron Sons was assigned to interdict all travel within the system as well to seize several orbital facilities. The remaining companies along with the imperial army were to land on the primary planet in the system to deal with the rebellion directly. Since it was almost impossible to tell loyalist from rebel, the Iron Sons force commander issued a planet wide order for all loyalist troops to defend themselves in place before crippling the planetary communication system. They then proceeded to land on the planet to track down the rebellion leadership. It was at this point that the operation turned into a disaster. Like other imperial army units, large numbers of the imperial army that landed with the Iron Sons joined the rebellion and turned on them which quickly put them on the defensive. Upon learning of the bad news, the sector government bickered at what to do next. However, before the sector government could reach a decision, the Iron Sons with assistance from their company that remained in orbit managed to regain the initiative, fight through their own forces that now stood with the rebels to face the leader of the rebellion that they brought to imperial justice. At this point the rest of the rebellion collapsed into disorder. The Iron Sons along with loyalist army forces routed and destroyed the remaining rebel units. The leader of the rebellion was later identified an an enigmatic figure called the Singing Witch was under enslaver control.
Codex Astartes The Iron Sons have their own interpretation of the Codex and mixed reverence for Guilliman and his teachings. As a result, they are viewed with distrust by some chapters.
They do not follow the Codex Astartes when it comes to company colors. They simply designate company affiliation with company number on the right knee or shoulder pad.
Geneseed It is unknown, but it is strongly assumed to be Iron Hands. Their geneseed currently has no mutations or defects.
Battle Cry "Blood and Iron!"
Chapter Tactics
One of the reasons I am leaving their origins vague for the time being is that I really have not decided from what chapter they descended. It's a toss up between the Iron Hands, Imperial Fists and Ultramarines.
