Because post #16 referred to AR 30-6.
Quite so! Just interesting to me that no one mentioned the Navy regs up to my post . . . while some posters are versed in the AR, it is not applicable, per se, to the question from the OP. To continue to provide AR information on uniform questions for a Sailor seems a bit odd to me.

But we have quite the collection of good information to be culled into another sticky, perhaps!
