The other thing to remember AOG is that in the long term(such is the nature of battlefield casualties) our own troops will gain the benefit.
Yes, our surgeons have become world leaders in the field as a result of the amount of casualties they've dealt with but each one brings its own unique challenge and way of treating it, which further enhances the surgeons skill in this particular area.
The medics will gain just as much benefit as the soldiers, which means better treatment and prognosis for our troops in the future.
It's no secret that generally, advances in medicine are brought about as a result of conflict and the subsequent casualties and has done since time immemorial.
