For Reservist and Guard, is there a regulation that states facial hair is not allowed in Military IDs, even if you are not on duty?

Reservist are on "Duty" when on orders. I do not have to conform to AR 670-1 when I am sitting at my desk 29 days out of the month doing my daily job here at Microsoft. Meaning my beard and mustache grows out and so does my hair. With that said, I am glad that they post a sign at every ID card facility you have entered which gives no excuses on how one must look when taking a photo for their military ID which would take care of this ambiguity. If you look at the picture above that I posted you clearly see I took a picture with a beard and mustache that is not in accordance to the regulation that is in AR 670-1 and to be honest that is not the first time either. Both times the pictures were took when I was not on "Duty" and both times the ID card facility said, "No you are fine." My question still remains is it a policy that is unit dependent or regulation, because if it is a regulation than clearly there are some that are not following it.

That is what I am thinking as well Sir. I can abide by it, however it did catch me off guard today when I needed one to be made.
