[Fatum Me Ducat]

OK....
If you can get into the army with your tattoos, unless something in selection has changed in the past few years, they should do nothing to preclude you from getting through and into the pipeline. Furthermore, looking way down the road at the ICBM distance target, depending on what group you MAY SOMEDAY have the privilege of going to, tattoos may be the rule rather than the exception. Where I am located now, we actually have a local tattoo artist working inside our little enclave and its not because the indidge are getting work done... full sleeves are pretty common.

All that being said... What will prevent you from being selected is a poor attitude, poor pt, and poor land nav. As an SF baby myself, i can tell you that you have an uphill battle ahead of you. Join the army to serve your country in anyway that you can possibly contribute. IMO, you shouldn't join if you can't live with the consequences of being an infantryman (I use the term consequence loosely). Because, odds are, when you don't get selected, an infantryman is what you'll be. Have a goal to be an 18 series and do everything in your power to attain that goal. However, don't be the guy that when asked the question, "Why did you join the army?" You answer, "Cause I want to be SF." You should join to serve and live out the aforementioned values. Your preferred method of serving should undoubtedly be as a Green Beret if that is the path you so choose... Just remember that it's a privilege to serve. If you make it, you will go through a certain school in the pipeline someday where you'll learn how true a statement that is.

PS- A Long Tab tramp stamped across your lower back is a great way become friends with selection cadre. And, as such, become insta-selected.

PPS- Just kidding. Don't do that.
