Okay, I'd say his job might be a huge factor here, we don't know how long he's been with the FBI now, so maybe he was still with the military when they were together. I'm not going to say that his job as an FBI Agent is not dangerous, but I'd think that his previous job as an Ranger/Sniper was more dangerous.

Looking at all three points you made Andie, I'd say it is most likely that all of them came into the mix at one point. And that's what makes me even more curious what kept Rachel from marrying Booth .
