What rank did you hold the longest?

10 years in grade as an E-5 (Air Force Staff Sergeant).

I was a csm from April 1991 to March 2011. A total of 20 years, retired with 42 years 2 months.

I was Major (O4) from 1993 until 2002 when I retired. (I was never, never going to make O5.) I think I was the longest serving time-in-grade Major in the US Army at the time.

Captain

This has got to be a record of some kind. When I was a 2LT in the guard, there was a guy in my platoon who had been a SPC for 39 years. Back in those days there were lots of 50+ y/o E4s. Guys who just liked being in the guard and didn't want the responsibility of being an NCO so they never did what it took to get promoted.

I was a Major for almost 9 years

SGT E5 6 YEARS

E6/PO1 was my longest held rank.

CSM, for nine years, and SGT and 1SG tied at four years.

SSgt was the grade I held the longest. 4 years during My first Eight years then after a 8 year break in service when back into uniform, still came back as a SSgt but lost the time in grade so held that for 2 years before being promoted to TSgt, so approx 6 years total as SSgt, once past that again sailed quickly runner up on longest grade held then would be SMSgt The break in service was the only reason I held the grade of SSgt as long as I did as I made SSgt in Four years but turned down TSgt at 8 years and got out. I thought I knew more than I did and found out being a civilian isn't all its cracked up to be. Like they say, the grass is always greener in the other fellows lawn until You get there and find out half the lawn is dead.
