I have tattoos, after I got them I was told I could be disciplined for getting them. My NCO said I caught him on a good day so keep them covered and go from there.
Why are we in such a rush over this aspect of the reg? It hasn't even been published yet and commands are in a hurry to enforce something that isn't even officially here yet.
As for discriminating against those people with tattoos? Absolutely this will be a discriminator. If you think otherwise you are naïve. If it was not supposed to be a discriminator, then this record would be filed in your medical records and screened by a medical professional. The fact it is going onto your OMPF means boards WILL have access to your tattoo file and will take it into consideration when not selecting you because you have tattoos. Of course this will never be made public because it would open the Army up to all sorts of legal trouble.
I understand the no tattoos on the head neck and hands, but sleeves and legs? These areas are covered 95% of the time by your duty uniform. I still wonder where all this hate for tattoos is coming from; was someone picked on mercilessly by other Soldiers with tattoos?
