I had to get two tattoo waivers in order to get into 188... From what I have learned, the current commandant does not like tattoos all over his Marines. Excessive amounts hurt your chances as do location (must be hidden in PT clothing), and the aubject of the tattoo also effect the decission. If it isnt tasteful (your wings would most likely be fine) then you would be screwed. I almost couldn't even get a waiver for one of my tattoos (a celtic cross) because some gangs are using celtic crosses now, however, I explained that my tattoo has to do with my presbyterian background, and it is a custom tat that is nothing like any of the gang tattoos, and there was no problem. When you fill out the forms for the waiver, your OSO will take a picture of your tattoo, another of you covering it with one hand (to show that it isn't huge), and you will write a statement explaining what it is, what it means, and why you got it. If you can handle all of that, go for it, if not... just wait untill after TBS, the tat parlors will still be there in a year.
