I would recommend to the OP that they not put too much focus on whether specific fellow candidates have an advantage when applying to college or for ROTC scholarship selection based on gender, prior service, being the child of active/ past servicemen and women, height, looks, religious affiliation, dog vs cat person, trump supporter, etc. Just put your focus on filing your best applications, do your best and let the chips fall.
For any number of reasons, there is often not a level playing field in life. Nepotism, age, gender, the one I hear a lot is how a coach's son in little league can't catch a ball but is a starter - someone gets an opportunity or edge. This continues in one's professional life.
Quickly, sometimes there are valid reasons for that advantage. Just sayin.
I would assume on specific years a qualified female candidate for example may have an advantage if there is a shortage of candidates from that gender. But why focus on this, what do you gain?
Who gets to go to the conference, who gets to go out to the special dinner a vendor is sponsoring who starts in little league - - just keep your nose to the grindstone and everything will work you/ you'll get good chances in life.
Good luck to you.
