The Adeptus Astartes
Hail, brother-captain. You are the first and last line of defence for the Imperium. Within your veins flows the blood of generations of warriors. You hold within you the genetic legacy of the Primarchs, as do we all.
We are peerless throughout the entire galaxy, but we are few. We are the example to which all of humanity must strive. We are the vanguard of the Emperors armies. The Imperium gives us much freedom. Almost complete autonomy in fact.
The tenets of our existence are clean:
Purge the Mutant.
Exterminate the Xenos.
Bring justice to the Traitor.
We are more than just men, we are the Space Marines!
Special Rules:
Your capital plant has the Marine Chapter Homeworld template applied to it. There are special rules for recruiting space marines which as found in your army list.
You do not need a transport vessel to transport Space Marine Scouts, Battle Brothers, Terminators, or Thunderhawks.
You must choose whether you follow the Codex Astartes or not. Those who follow the codex and limited 9 total companies of Terminators and Battle Brothers. Those who do not follow the codex do not have this restriction, but will also be under close scrutiny by the Administratum and may be subject to genetic taint.
State Creation limits:
You cannot play a first founding chapter, a major chapter with an army list or that features heavily in the game (Blood Ravens, Black Templars, etc.).
You may choose a chapter for which you are the successor for, or you may not know. Otherwise, you are free to do whatever you want. Remember, you are a loyal chapter. You may go renegade during the game (if you have very good story reasons) but you may not start out so.

Planetary Defense Air Group: Basic air support, mainly fighters but with some bombing capability.
Cost: $100

Cost: $90
Production Requirement: 2
Imperial Guard Armoured Regiment: The armoured wing of the Imperial Guard.

Space Marine Battle Brother Company: The supreme warriors of the Imperium. Gods among men, these powered armoured behemoths rarely take to the field in pitched battles. Fighting in hundred man units, the Adeptus Astartes rains from the heavens in drop pods or run guns blazing from a landing Thunderhawk gunship. As quickly as they came, they are gone. Whomever or whatever their target is only a memory. If you dont know who these guys are, you shouldnt be playing.
Cost: None. Automatically promoted when enough scouts earn their place as full battle brothers.
Upkeep: $60
Production Requirement: None
Terminator Honours Company: The greatest of all marines are honoured with the Crux Terminatus. This highest honour allows the Marines to don Tactical Dreadnaught Armour.

Upkeep: $100
Production Requirement: None
Thunderhawk Gunships: Thunderhawks are the best fighters available to the Imperium. Capable of both air and space combat, the Thunderhawk is the most versatile weapon in the Imperial Armoury.
