I've been in the Armed Forces my entire adult life. Did you serve? 
I have not, but my grandfather, aunt and stepdad have. Thank you for your service!
Thanks I signed up after 9/11 left to serve at 17 years old and still in. First in the Marine Corps now in the Army.
Wow thats great, how do you switch from one to the other? I havent really heard of someone doing that before
You can switch ever 4 years if you want. I'm thinking of retiring in the next few years and working with the Department of Defense (DoD)  after that. 
Oh okay I see. I hear about the DoD or people who have worked with that, but I dont know much about it. Can you tell me what all they do?
The Department of Defense hires you as a contractor and send you to work with small teams in war torn area's. 
thats interesting, is it hard to be away from your family so much? Thats something nearly everyone in the service has experience with
