In 1980, I put on Sergeant from Senior Airman. In other words, I got my white star.
I was then a white supremacist among all the airmen.
I went from SrA to SSgt in minimum time, and because you cannot be promoted from SrA to SSgt directly, you are promoted "Sergeant for a Day." As a fluke, the date of the promotion ceremony fell on the one day I was Sergeant.
So after asking around on whether I should show up to the ceremony with my SrA or my Sgt stripes on my uniform, I decided to be technically correct and have Sgt stripes sewn onto my Combination 1 uniform for the ceremony, and separated less than a year later.
I never did have SSgt strips sewn onto my Combination 1 jacket.
In 1977, as a A1C I was promoted “below the zone” so I was only a Senior Airman for a month. I simply sewed on my buck sergeant stripes but kept covering up the white star with blue ink and when the month was done, washed the shirts and they became white stars again.
