I read new stuff, but can't keep track of every author.
Anyway, if you like military SF, you're probably familiar with these; if not, give them a try:
Heinlein's "Starship Troopers" (almost nothing like the movie), basically the Pacific war in space
https://audiobookbay.lu/audio-books/robert-heinlein-collection-robert-anson-heinlein/Joe Haldeman "The Forever War", which is a reply to the above, written by a Vietnam vet.
Gordon R Dickson's "Dorsai" series -- space mercenaries.
https://audiobookbay.lu/audio-books/childe-cycle-dorsai-series-gordon-r-dickson/James A Comey: The Expanse series (as seen on TV.... hard SF, the tech and weapons are [pretty realistic, mostly Cold War, but occasionally goes hot.)
