As this Reddit comment explains:

1. I'm curious if anyone out there has any suggestions for military scifi with a Soviet/CCP aesthetic. I'm looking for like, Stalingrad in space, if there's a critique of Communism in the writing that's fine, if there's not that's also fine. I just want some military scifi where the space marines scream, "For the Revolution!" instead of "For the Emprah!" If I can't find it I might just have to write it myself. If I find it and don't like it I'll definitely have to write it myself.

2. It's a comic book, but The Red Star has a lot of what you're asking for.
