Badass John Sheppard

[doomsdaybrnete]

We all know John Sheppard is depicted as an exceptional pilot, but not many people write about any other training he might have had.

I would love some recs of stories that are about or just talk about, flashbacks even, John's military training/record before Antarctica/Atlantis. Was he special forces? special ops? special tactics?

No ship necessary, although I love a good McShep.
