but if the situation calls for it, why not.
I am assuming of course it is an MO, a person who is medically
qualified to assess the situation and say if it's going to prove a
risk to life.
Although medics are trained, on the ground they should seek to
advice commanders on what to do... and not outright try to overide
their decisions.
But then again... a life is a life. If it's glaringly unsafe, just
say it.
