Among the Space Marines, the highest ranking officer in a Company is a Brother-Captain, who is commander of the company.
Among the Legiones Astartes, Brother-Captain was not confined to Company commanders, but also to special squad commanders. For example, the Luna Wolves/Sons of Horus First Company maintained two special Terminator squads, the Justaerin and the Catulan Reavers (who are actually a jump pack using ASSAULT SQUAD!), under the command of Falkus Kibre and Kalus Ekaddon, who were lauded and celebrated heroes of the XVI Legion, but still had to answer to Garviel Loken, who was a full Company Captain.
Masters of the ChapterEdit
After the publication of the Codex Astartes and the breaking of the Legions into Chapters, Brother-Captains were confined to Company commanders. Each Captain was given an aspect of command over the Chapter. Alongside the leaders of the Librarium, Chaplaincy, Armory and Apothecarion, the Brother-Captains hold the positions of Masters of the Chapters. Here they both serve as a board of advisors to the Chapter Master and hold a variety of positions within the Chapter with associated duties. The ten positions for a Codex-compliant Chapter are as follows:
- The senior most of the Captains is the First Captain, who is Captain of the First Company and holds the title of Regent. In the time of the Legions, the First Captain was generally considered the very best warrior of the Legion after his Primarch. In "modern" Chapters, the First Captain commands the veterans of the Chapter, and serves as the immediate second-in-command to the Chapter Master and Regent of that Chapter's home world or fleet. In a few Chapters, such as the Salamanders and the Crimson Fists, the Chapter Master is also the First Captain. While theoretically any captain could wear terminator armour, because the First Captain is the one directly responsible for leading terminator squads, he is almost exclusively the one captain to bear terminator armour to battle.
- The Captain of the Second Company is the Master of the Watch. Charged with maintaining discipline, they serve as the prosecution during trials within the Chapter and handle other cases involving a lack in discipline but that are not quite heretical. Their main responsibility though lies in the logistics of defense for the chapter's Fortress-Monastery/main base of operations. In fleet bound chapters these responsibilities are often rolled into the title of Master of the Fleet.
- The Captain of the Third Company is the Master of the Arsenal. They oversee the Chapter's stockpile of weapons, munitions, vehicles of war and their quality. Likely works closely alongside the Master of the Forge.
- The Captain of the Fourth Company is the Master of the Fleet. They are charged with taking care of the Chapter's Fleet. It would seem logical that this position is more important in fleet-based Chapters, as the ships are even more important to the Chapter.
- The Captain of the Fifth Company is the Master of the Marches. They have the duty of overseeing the Chapter's deployment and fighting strength: when a Chapter is rebuilding for some reason they have the final say when the Chapter is ready. Their duties require an immense amount of time and effort; it is not uncommon for a Master of the Marches to spend all of his time on the incoming data, which does not seem like the thing a seven foot superhuman should spend his time on. (Except that a chapter-master wouldn't take the news that he needs to construct additional pylons before launching an assault from anyone other than a senior staff marine.)
- The Captain of the Sixth Company is the Master of the Rites. They perform and oversee the rites, rituals and other formal occasions inherent to the Chapter; as such their duty (and the size of it) differs between the various Chapters. In many cases, they work closely with the Chapter's Chaplains. The precise differences between Master of Rites and the Reclusiarch vary greatly between chapters, generally with both holding special significance under different spheres.
- The Captain of the Seventh Company is the Chief Victualler. They are tasked with maintaining the logistics within the Chapter and with outside forces: that the supplies that the Chapter cannot make for itself are procured and that there are enough rough materials for the things the Chapter can do. They also make sure that the various ships and bases of the Chapter have ample supplies. Synonymous with Quartermaster.
- The Captain of the Eight Company is the Lord Executioner. Unlike his brethren, the Lord Executioner serves as a weapon for the Chapter: to be bloody in battle and destroy the Chapter's enemies in close range.
- The Captain of the Ninth Company is the Master of Relics. Their duties are twofold: to tend to the various relics that the Chapter has and to engage in long-ranged warfare, both in sieges and firefights. Rumor that this duty also includes warding any and all Blood Ravens from the armory is unconfirmed.
- The Captain of the Tenth Company is the Master of the Recruits. They oversee the recruiting, indoctrination, training and deployment of the Chapter's Neophytes and Scouts.
I Can't Believe It's Not A Captain™Edit
Some Chapters use different names for their Captains. Unlike Chapter Masters these almost never have significant functional differences from the Codex standards, since their job of "commanding 100 marines" is fairly straightforward. For instance:
- Dark Angels - "Company Master"
- Space Wolves - "Lord" ("Jarl" in Fenrisian)
- Red Scorpions - "Commander"
- Black Templars - "Marshal"
- Raven Guard - "Shadow Captain"
- Excoriators - "Corpus-Captain"
- Iron Hands - "Clan-Commander"
- Grey Knights - "Grand Master"
- White Scars - "Khan"
Also, the Crimson Fists 1st company is not led by a captain, but rather by the Chapter Master.
In Warhammer 40,000, Captains are sold to be customizable for the player to have the Captain serve whoever they want. However, it's overly expensive for something so fairly useless in its primary purposes: fighting and dueling. If you're going to use a Captain, use a Special Character. Alternate take: Captains are more survivable than most other marine HQ's and fulfill the requirements for the demi-company formation. As such, there is cause enough to use them.
In 8th Edition Captains have become much more viable with a useful aura ability which allows for re-roll hit rolls of 1s for your chapter units. This works for both ranged or CC oriented play styles and can work with different HQs, like the Ancient (for that retaliation) or the new Lieutenants (for making those 1 re-rolls hurt). Works even better with the new plasma mechanics, allowing those 1s to become a fail or hits instead of instant death.
