I have tats, and my belief has always been, "want what you get, and get what you want"
Mine are all original, not "cookie cutter"... nothing irratated me more than when I was a 29 Palms CA going to comm school and every other Marine out of Boot Camp got the same tattoo in one of three sizes... the globe, with the dagger through it. Geez! Tattoos are supposed to represent the individual... now, I never saw your first post, and I think the barcode could be cool, but everyone will think you are trying to be one of the "genetically engineered" super soldiers from the TV show "Dark Angel". I would recommend NOT getting the Drivers license number, cause if you go to another state and change your driver's license...you could get a different number. only number that would make sense would be SSN.
Now as for the military looking down on your tattoo.. never happen unless it's some woosy "loveme" thing. I saw many Recon types at the beach that had name, blood type, and SSN tattooed on the side of their chest on the left side a la WWII SS troops.
I have been considering two more tats for awhile. When I worked Downtown Detroit Security, I considered getting a bracelet tattooed under my watchband of name, blood type and SSN. Figured if I was in an accident or taken to a hospital, someone would have already stolen my wallet... and the other is a tat to commemorate my daughter....cause she'll ALWAYS be my daughter. Told the wife years ago before we got married, her name would never be tattooed.
Do what you want....just "ake sure you get what you want and want what you get."
