If you’re willing to give a try to military SF, try David Weber, John Ringo or Jerry Pournelle. Particularly Pournelle’s Lucifer’s Hammer, Footfall or The Mote in God’s Eye.

The Doc Ford novels by Randy Wayne White. I’ve read just a few and am still not sure whether the author is liberal or conservative.

John Ringo is a freeper.

I have several of Jerry Pournelle's books and my favorite one is one he wrote with Larry Niven and Michael Flynn called "Fallen Angels" you can download a free electronic copy at Baen Free Library if you want to check it out.
