It makes sense that they would choose to do it differently because of this though. What other reason could they have to wait to place people? That is not rhetorical question. I am legitimately asking.
Simply because they don't give any benefits or remote concern for those with families, spouses, kids, houses, etc. You will see this when it comes time for base hospital choices.
Believe me, I would be happily proved wrong if it's for preference for those with families, etc. However I would guess they are actually doing it for reduction of administration work.
