While I respect those who join the military to serve their country, based on his interview with Ryan and Rachel (and his anti-Islamic bigotry), I think its pretty clear that Caleb joined up because he wanted to kill some Muslims -- and was disappointed when he wasn't assigned to some "cool convoy ops kind of stuff". Instead, he "didn't like his assignment 'cause I was working with these people face-to-face". In other words, Caleb thought that war was like a video game where he would be able to shed lots of blood doing "cool ops", and wound up whining about his deployment because he was required to treat Muslims like human beings. IMHO, that is not service worthy of respect. Indeed, Caleb comes off as precisely the kind of person for whom the phrase "Ugly American" was coined. I predict that 1) caleb moves to Los Angeles after BB 2) he comes out of the closet within a year after moving to LA 3) he is arrested on a domestic violence complaint two years later Basically, the Drew Daniel arc.
