My sister got her Bachelors in psych in 98, unless you plan on going for your masters don't bother with psych.
Business is a little more useful without the masters. But maybe you should consider what you want to do after you are out of the military, if for instance you want to work on cars and open your own shop the business classes wouldn't hurt. There isn't much point in taking classes if you aren't going to use them though.
