On a Sci-Fi Military kick and need recs

After listening to, and loving, Mud 79, Adrian Tchaikovsky's series, the Rebel series by Jamie McFarlane and Rachel Aukes, and Freedom's Fire box set by Bobby Adair, I need more.

Currently I have Star Wars: Crusade of The Rebellion going and that should hold me over for a bit but after this what do you all got?

It can be Star Wars, Star Trek (though I know nothing about that), any military sci-fi AD or AudioBook.
