Say you want something really competitive, like seals or EOD, how is it determined if you get a billet? And when are you told that that's where your headed? I'm not in rotc currently, but I'm entering my sophomore year and I'm considering becoming a college programmer. What does it take for getting those jobs? If you have a great GPA, speak another language maybe, and do really well fitness-wise (90 push ups, 90 sit ups, 9:00 1.5 mile), are you a reasonable shot?
