If the bottom quartile is fit enough to do the job. Why do they need kicking up the hoop? Hereford has a bottom quartile.The point is to make a unit commander's job as easy as possible and not to screw around with a bit of the army that works in order to make a sociological point. A bloke in the physical bottom quartile can be kicked up the arrse; a woman in the bottom quartile is probably giving everything. Straightaway the choice is between being unreasonable and treating people differently.
The command problem becomes even worse when the choice is between choosing the best people for risky tasks and trying to keep risk exposure equitable across the team.
