I have to agree with Anticitizen on this point.'Marines' = combat roles. I'm tired of 'Battle Trek'. DS9 did the interstellar war thing so well that I feel it never needs to be revisited. I want to go back to Trek being about intrepid explorers that occasionally get into scuffles, not MACO/Section 31 tripe.
DS9 did Trek war (and did it damn good, IMHO), so there is really no need to revisit that. The next Trek should be about the aftermath and hardship of war leading into the return to peaceful exploration.
Whilst I have no problem with the concept of Starfleet Marines, personally I'd prefer not to have a series that featured them heavily (and the less down about S31 the better, I think). They would have their place and duty to serve, but as we've seen time and time again, general security guards are more than capable of handling just about any situation.
It always amazes me just where what tangents some topics end up going--often having nothing to do with the OP
