Even so, Space Marines will work with other Imperial forces, as all are fighting for the best interests of Mankind. However, Space Marines also have a history of looking down their noses even at other military forces within the Imperium, regarding Imperial Guard and Ministorum forces as "only human". Space Marines: Space Marines hold the "typical" Imperial view of other races: They are untrustworthy Heretics who should only be regarded as subjects for conquest. Quoting from ' Using Allies in Warhammer 40,000' here is a view of space marine allies in previous editions: ( of the 3rd edition rule book) Space Marine Chapter allies backstory:


From what I can tell you could just add any unit you wanted to your force.Ĭome third edition, these rules had gone and been replaced with a system for using multiple force organization charts to field multiple armies. Previously in second edition there were rules in each codex for who could ally with who, specifically mentioning which armies you were allowed to team up with. “There’s just too much that can go wrong and you’re virtually guaranteed to lose all your money.” No vehicle that exists today would be an adequate transport for space marines, and it would be extremely expensive to develop a new one.TL DR Yes they can, however the rules for alliances vary by edition “We in aerospace engineering have rules against developing a launch vehicle” specifically for one program, Kirkpatrick explained on Thursday. The vehicles would also have to be modified to accommodate life support and an air lock, and the cost and time needed to develop such a vehicle makes the possibility a remote one.

However, no such vehicle has been flight-proven or human-rated at the required scale. There is also the Sierra Nevada Corporation’s “Dream Chaser,” which could carry seven astronauts. Aerospace manufacturer Boeing has proposed plans for an X-37C, a human-rated version of the X-37B test vehicle used by the Air Force, which could carry up to six astronauts, Kirkpatrick said. As of now, there is no small vehicle that could take a fire team of four or so Marines up to geosynchronous orbit, support them exiting the vehicle for a spacewalk and take them back to Earth.

But getting the space marines to and from the communications satellite is the real challenge.
