I am a military veteran. There are all kinds of branches like the Navy, Army, Airforce and Marines. I was in the Army.
Thank you for your service! My son is currently in the Army National Guard. 
That's cool! They Army National Guard works in conjunction with the Air National Guard as a federal reserve force for the U.S.
Sweet! What year was the Army formed?
I'm not really sure of the exact date however the military can also be involved in building schools, housing, and hospitals as well as defending our nation.
Oh, that is awesome! You learn something new every day! What else can you tell me about the military?
The actual task of the military is to defence of the state and it's citizens.
Well, I am very proud of our military. I know they sacrifice a lot. 
Yes our soldiers are amazing!  Another use of the military is the darker side, like promoting political agendas and protecting corporate economic intersts.
