Possible con is that you're selecting your community very early and possibly knowing very little about it. For instance, if your three choice are Intel, SNA, and SWO, and you get picked up for SWO and accept that, but all your research, interviews, etc, has been concentrated on Intel, well, you're going to be a SWO (again, if you accept that). But still, you'll be the best-compensated SWO on the boat arriving with--assuming two years in the BDCP--60 days of leave on the books, one year until a major pay jump, and two years of credit towards retirement. If you're sure that you want to be a Naval Officer, do your homework, and have half a backbone, it's the best--and I mean BEST--deal going.
