Just me…but I think you may be confusing "Base Gate Guard", "Base Security" cadre, "Pier Access Guard" (and maybe even more layers) with "QD Watch". I think the last is mostly about protocol, visitor greeting, etc.... QD watch is a force protection thing, so why the hell would you be in a dress uniform for it?
If the QD is where you think FP resides…well, you've missed some better options.
