Praxis and subsequent books. It's spacewar.

Old Men's War. SF elite troops warfare vs aliens.

Praxis? Sounds interesting. What's the setting like?

Old man's war and sequel was excellent

The galaxy's ruling race have died out, and their vassals (humans included) do battle to establish higherarchy. It uses wormhole travel, not warp or hyperspace like other series.

This is highly, highly intriguing. Reading the books synopsis now aswell. Thanks for the recommendation!

Check the Spiral Wars series. This setting starts out as humanity ends their first great intergalactic war as the newest member of the space faring spiral community. A conflict that nearly wiped us out.

The series focuses on the capital battle ship Phoenix as it is used as a scapegoat for a navy coup. The first novel mostly focuses on Phoenix and it's officers as the ship goes on the run from humanity's own navy. The subsequent novels chart Phoenix journey far beyond human space as it slowly uncovers a threat to the entire spiral galaxy.

The two main characters are the captain of the ship and the major who commands the ship's power armoured marine corps that is used for boarding and ground actions.

The whole series is very militaristic as Phoenix makes allies and enemies in its quest to uncover the threat and find a way to fight it. There's a ton of space battles that focus heavily on the complexities of ship to ship warfare while the marine company provides plenty of hard as nails up close action, both in and out of their power armour.

Some very good mega series: Star Wars and Warhammer 40k. For Wh40k, start with the Horus Heresy.

Don't know the name of the books but the serie The Expanse is based on books that supposed to be really good.

Terms of Enlistment by Kloos is almost certainly what you're looking for. I'm not sure why you think it doesn't exist, there's tons of military fiction.

I fell in love with the Expanse series, was very saddened by the early ending. Those books are on my list.

Red Rising series

Yeah same. Found the last season pretty weak though. Felt a bit rushed.

Yeah, love both 40k and Star Wars. Have been addicted to Star Wars since I was a boy, and have read as much of its military fiction as I can.

40k for me is a newer interest, and I'm not as much into the lorebooks, but I love the aesthetic and the stories in universe.

For certain. Set the bar for modern Space Opera TV imo, though Andor is getting there. Just need to see how Gilroy does space combat and my verdict will be in.

{{On the Beach}} by Nevil Shute, perhaps!

It's not so much that I didn't think it existed, I have been reading military sci fi for years. I could just never find a book or series which delved into the darker aspects of conflict and it's aftermath, things like PTSD, the oppression of war, how war changes societies etc. In the books I have read.

Sci fi-Fantasy Mil-fiction that I have read previously focused much more on laser blasts and underdog victories than the philosophical and hard hitting introspection that I have been searching for. Not to say more straightforward mil-fiction isn't fun, i really enjoy it. I'm just looking for something a bit deeper atm.

I will look up Terms of Enlistment though, sounds interesting.

Hammer's Slammers by David Drake. Follows a mercenary tank regiment.

If you enjoyed the show you’ll like the books even more. They start with Persepolis Rising and are written by James S A Corey if you’d like to look them up at your local bookshop. By far May favorite series with fast paced writing that gets just enough detail and IMO a solid grasp on what zero G warfare would look like as well as a compelling political backdrop.

Hi there. Per rule 3.3, please post book recommendation requests in /r/SuggestMeABook or in our Weekly Recommendation Thread. Thank you!

If you don't mind a lot of religious backdrop with a near explicit evil Catholic vs good Protestant try Safehold by David Weber. It's a sci-fi series where the last colony ship was sent off into deep space with orders to go dark and emit nothing for a thousand years to escape the aliens that killed the rest of humanity. However, there was a revolt among the leadership and instead of knowledge being preserved it was destroyed with an oppressive controlling church put in charge. Now a robot is charged with ending the church in order to revive humanity's tech base to take the fight back to the stars. We are 10 books in and the key struggle is still against the not Catholic church.

Still, it does a good wide angle lens at different regions, some religious disagreements, scale and effects of the conflicts.

First book {{Off Armageddon Reef}}
