NicoloM:

Thanks for the excellent reply/Post.  For now, can you let me know of a site where I might find a McCain ad.  In the meantime I'll search around myself.  I've seen a few on TV but never pay much attention to them because of their inability to come near the truth on any issue.

As for officers, Clark is right.  Some officers never come near command positions because of their jobs.  Many pilots fall into that category, especially Navy pilots.  They rarely speak to enlisted men, except for those who assist them in take-off and landing.  But those men have Chief Petty officers (who are equivalent to sargeants) in charge of them.  

From anything I've read, McCain was never in a command position.  A command position in the Navy would be a Captain of a ship, in charge of Seabees, and so on.  No one hears of McCain in any of those positions.

I believe too, that you have to have command of a ship, a heavy Cruiser, Battleship, or Carrier in order to be recommended for Admiral.  These Captains have to be full Captains (an Eagle insignia on their collar, equal to an Army Colonel or Marine) before they can become Admiral.  Again I don't know McCains full story.
