If you like a touch of libertarianism, I'd reach for L Neal Smith. Politics aside, he is on the softer end of the scale. Even still, he took a go at some hardboiled/noir detective fiction in space with one titled The Wardove. If you can track down a copy you might find this one to your liking. I think he did a good job with it.
Ian M Banks strikes me as a nineteen seventies storyteller who was kicked into the present day and forced to swim through all our modern realistic/harder tropes. Use of Weapons was excellent. Consider Phlebas was more rough around the edges, though I enjoyed it and do recommend it. I have not had a chance yet to take in some of his door-stoppers.
Chris Bunch and Allan Cole's have written something known as the Sten Adventures. I skipped the first few books and started with number four, which hooked me sufficiently to finish the remainder when I was able to nab the ebook copies. I generally can't stomach too much milfic so consider this a strong endorsement. Fleet of the Damned is a great place to start, and even if you read nothing else in the series it will be worth it. FotD is a mix of Vietnam era helicopter space flight school days, World War Two PT gunboats gatecrashing nineteen sixties style Talos missile spamming starships, and grounded vagabond naval crews faking their way through Bataan. Sorry if that sounds goofy, Chris and Allan made it all work together. Read it and see for yourself.
