Don't forget that every battle barge is also a functioning muntions and machine producing facility. Must marine force have a small army of servants/servitors marines that washed out in training. They must likely do the majority of all the needed grunt work. For must its an honor to serve the chapter or they are just labotomized and only follow basic programing/instructions. They must likely get there resources from there varied planets that they recruit from as sacrafices to the "Angels of Death".
Must major Forge worlds are operated by the Adeptus mechanius since they are the only ones who know the "rights" to make just about everything. I imagine the contract fees generated by hiring the only trained professionals to make, designs and or fix your equipment would be pretty high. Not something you can really go and outsource. Since they will just call you a heretic then you get to deal with the Inquistion. |
