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.
