http://news.yahoo.com/s/ap/as_afghanistan My heart just breaks every time I read things like this and when there are troop deaths. This led me think about what Navy personnel do 'on the ground'. I tend to think of the service's responsibilities in a very narrow scope. Army - ground, Navy - sea, Air Force - air. I know there is overlapping ( ie- all three have air capabilities) but unless these Navy servicemen were Marines, I was wondering what other responsibilities the Navy has on the ground. Are there ground responsibilities for the Air Force? Can anyone enlighten me?
