I am thinking about joining Navy, what do you think about that branch of the army?
DO you like water ? Because it is principally a waterborne military force. 
I really do, i like diving too, thats why i am thinking of it in the first place, i hope when i enlist they send me to Hawai or something like that :D
Hawaii is a a strategic point in the Navy, because it permits to project US forces beyond its shore. 
Yes, i like to join it because its the largest navy in the world, and i would like to do something for my country
And if you want to be diver, the Navy is the place to be, it is responsible also for amphibious warfare.
