NASP has a large contingent of E-<4s. Not to dog on all Es, but judging by the military bearing (or lack thereof) I see from a few individuals whilst coming and going at the NEX, there is a somewhat sizeable minority of dirtballs there. Saw the same thing when I was here in A-pool as well.
According to the law of averages, congregate enough people in one location, and you are virtually guaranteed to run across not only dirtballs but bona fide shitbirds here and there. Large quantities of junior personnel mean small, but still extant, quantities of people who should be weeded out but haven't yet had sufficient opportunity to demonstrate their worthlessness.
Keep in mind that a few Ensigns recently proved that this is not purely an enlisted phenomenon.
