Soldiers are authorized to now wear (MILPER Message) any PPE that was issued by RFI. This would include Wiley X, Oakley glasses and such. Logos do not matter.
However, I have a SSG who always tries to wear these silver framed glasses, and I dog his ass. He says they were RFI, so I just told him to turn them in to supply, and I will get him a darker pair. Then he cried foul.
I am not big on unifrom regulations, since I am currently deployed. However, some stuff does not pass the common sense test.
