Well speaking of boot camp scenes, and later conflicts:

I can't see them doing it. The unit responses are cues for the player; putting them in a language the player doesn't speak denies the player necessary information.

No; didn't even know there were any.

As I say, not many of them.

Alistair Reynolds has a trilogy called Revelation Space, in roughly the middle of which one ship pursues another at near the speed of light; there are some interesting ideas about how they try to do each other in, but its not the main issue in the series, and the setting has some pretty wild super-tech. But the series is very very good in its own right, so worth a read.

C.J. Cherryh has some novels that deal at least in part with high relativistic interactions, Downbelow Station is standalone, otherwise the Pride of Chanur series.

Joe Haldeman's excellent The Forever War deals with the impact of time dilation. It was written as a sort of counter-point to Starship Troopers (and if you have not read Starship Troopers, as opposed to seeing the movie, you should).

More general military sci fi, not dealing with space as such, would include things like David Drake's Hammer's Slammers and sequels.

David Gerrold has a very interesting series in The War Against the Chtorr books, and also wrote The Voyage Of The Star Wolf, which is themed on space war, but not in the relativistic sense.

I also have a couple of military themed things which I enjoyed tremendously and which you can read online right now:

Morrigan in the Sunglare
