I have had quite a few. I have no desire for the responsibilities of those that are above me. I am 1st Sergeant, the only routes above me are Sergeant Major, Sergeant Major of the Marine Corps, then the various Warrant and Commissioned officers.
I enjoy field and dirty work too much to be behind a desk all day. I had to fight tooth and nail to keep doing the work I do as it was but I've been in too long for them to have not promoted me this far.
