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. 
I think the same thing, i read a lot about the navy seals, but thats a whole new level of commitment, i dont know if im ready
Yeah, but for be a diver, you would have to apply in the Marine Corps. They are the unit responsible for the amphibious warfare. 
I think i will, you cleared my mind also six U.S. presidents served in the US Navy during WWII, i love it for that even more :D
It is corps with great history, the Marine Corps were founded in 1834.
