What are the odds of me getting this AFSC "Air Force Job"?

If you passed the PAST for eod, you have a pretty good chance as that's a job that is not fully manned and needs people. Same with the other afsc's but you also need a PAST for them, 3 different ones, if you don't pass them you won't get any of those. Here's your problem, you listed security forces. There may come a time when security forces becomes available before eod, and let me tell you it's likely, and you will need to accept it. I've seen it happen to alot of people.
