Last year (2010) I got into some trouble with the AF. Underage drinking. I was 20 years old, an E3. It happened off base, and it was later thrown out in court. The following duty day after it happened, I went to my first shirt and told her what happened. The commander and stuff got involved, but in the end all I got was an LOR. I wrote a rebuttal (which my shop chief read just today, and gave me props to how well written it was) and pretty much just told my commander what happened. I was at a nearby college, and wanted to make some friends, so I had a few drinks. At the end of the night I realized that I was NOT okay to drive, so I slept in my car, and a police officer found me in my car.
I work MX (ammo), and from what I've heard, this isn't too much of a big deal, especially since I admitted to making a mistake and kept the stupid choices that night to a minimum.
How does this stand in the eyes of a Guard/Reserve interviewer?
