Sure they do... all paygrades are written in the same manner. E-1 through O-9
That's why I put both "titles" in my signature block, as per my "user name" is my Army grade, not CAP, as I plan on getting promoted sooner than later....but my retired grade will always stay the same.
I have seen two first hand that were SSgt. They are content with their choice. Just because you do not understand the reasons why, that doesn't mean that they do not have good ones.
Interesting that now they seem to have eliminated the CAP NCO Grade of SGT. I can't imagine anybody wanting to hang on to their enlisted grade if they were below E-7....
I was actually just making an observation because this thread began (in 2006) mentioning the NCO grade of SGT, and apparently that was removed sometime a little bit more recently than when the AF did away with it.
Again, I will refer you to the first page of this thread, where it was cited in 2006.
