I've had the privilege of sitting on selection boards and I've had the privilege of doing force planning and force rotation and it does look at your merit selection, your background. "Look, she's skilled". and it's not just one person doing that selection. You've got a group of people that will sit down and consider not only is it the right person for that that position but also noting the importance of the positions that you're filling that it's going to support the mission.
And so I believe our Australian Defence Force does it better than any organisation that I know, even our public service, when I sit on selection boards, I always draw on that experience on selecting the right person.
