I trust all of the U.S. Military Branches, if a leader is a good leader, then I wouldn't care if he wore a Navy , Air Force, Army or Marines Uniform. Inter service rivalries may be positive sometimes, but things serious like this I don't see the point of it.
If after this Navy officer trend is gone, a Air Force, or Army or Marines trend follows, as long a they do a good job I wouldn't complain. I would respect that person and the uniform they may be wearing, whether it be a Admiral or a General, and still recognize the branch they represent.
What I just said is complicated, but, basically its how they manage the job at hand that matters to me. Although I am not in the military (hopefully yet) I still know that guys with the right stuff are keeping a steady hand on my country's military affairs and defense.
Oh and , Admiral Micheal G. Mullen
, I will remeber that!
