Hey Dave,
I am currently attending college for a BA in Criminology. I do not have any relation to the military other than some family serving, and an interest in joining after college. I have been playing Arma 3 now for less than a year, although I have played Milsims since about 2006. I think milsims are great fun, and quite different than your average mainstream shooters these days. I enjoy the level of interaction involved while playing, but also the social culture, which tends to be more mature than other gaming communities. That's my thoughts anyway.
