Thank you Jimlad!
As I understand it the issue is that in mixed groups the pace is 27". The instructors chose not to follow the clear rules and instead forced the women to march at 30", causing them injuries which led to their being medically discharged.
It was the instructors that chose to disregard written policy, not the recruits. Despite the Daily Wail's usual attempt to inspire anger and outrage on behalf of "Middle Britain" if anyone should be made to pay for this, it should be those responsible for ignoring the policy.
