It seems like you would prefer a Federation that has a purely military subdivision. Starfleet, as depicted, does not seem to be good enough in that it is almost always on the fence between military and civil service and so is not very good at either.
The thing is, StarFleet has leaned too heavily into the Explorer / Scientific side. When it needed to be ready to be a military at the drop of a dime, it was slow to react and that resulted in countless deaths on their own side.
My belief is that a 50/50 balance is in order. Yin & Yang. For Military Readiness / Scientific Explorer.
It is organized somewhat like a military organization, but it is way too busy not looking or acting like one, even when at war.
I would not be at all surprised if even a 21st Century SWAT team (for sure a Stargate SG-1 team) could take over an entire starship if only they could somehow land near the bridge and the officers on it.
That's a fundamental weakness with it's readiness, how many times has a StarFleet outpost or Vessel been taken over by a boarding party? Far too many for my tastes.
So, questions…
Do you imagine a Starfleet with an entirely hardcore military subdivision within it that is always on the ready while the rest of the Fleet does its half-hearted thing, or do you imagine a Starfleet that maintains a certain half-hearted level of readiness that ramps up in stages given the circumstances until it finally reaches a hardcore level (one that we have never seen as of yet) when required?
StarFleet doesn't have to be a 100% entire HardCore military, but it has to be competent enough that when push comes to shove, that it's ready to do what it needs to do.
Even the US Military has their scientific research & general R&D departments.
They also have plenty of civilian aid and other missions that aren't just pure warefare.
Like I said, Yin & Yang. That 50/50 balance is critical.
This might affect your scheduling.
Also, what Star Trek era do you prefer?
I prefer the Berman-Braga era of TNG -> VOY.
That part of the 24th Century I do enjoy.
I’m good with the motion picture up to Star Trek III. That’s where I like to stop the clock.
I have my own 26th Century Head Canon that I'm working with that takes every existing Canon and works it into it.
Yes that includes Star Trek: Discovery and the 32nd Century, there are certain events and actions that I'd have Michael Burnham fix / retcon to provide a superior & brighter existence into the future of UFP & StarFleet along with ensuring that the future timeline of the UFP is protected long into the future.
