Now this is just fun! That's OA for ya, though I'm always impressed with how skillfully you can mix different types of guitars, piano and other orchestral elements, and synth together to form such a cohesive musical package. The acoustic guitar (I'm pretty sure that's what I'm hearing, anyway) sounded really fake, even though I'd venture a guess that it was performed live, since this is a DoD track. That's kind of weird, but it's such a minor element in the overall picture that it's hardly worth mentioning.
