Going back many many years. Should you be able to look squared away when you're in dress uniform? Fuck yes. Thing is, Dress uniform has a tall collar, tie, and long sleeves. Anything on your neck? yeah, that's derpmode... but PT shirts and brown T's in the platoon bay or doing PT? Guess what, there's a goddamn warrior that wears those tats most often due to the meaning they have for them incorporated into their personal warrior ethos and all that shit.
I mean, I have limited ink, but I'd stab a commander in the gut if they told me I had to get either removed. Seriously.
When I was at JPAC I thought that the Army guys with neck and hand tattoos looked pretty unprofessional. Sleeves are one thing but neck, hand and back of the head tatts are something else.
