Reversed triage priorities?

1st situation
"[I]magine a battalion (approximately 400 soldiers) is facing an enemy force of about 550 soldiers and that each force is equipped with comparable weaponry. After several hours of fighting, 50 soldiers in the battalion are wounded. Most of these wounds are life-threatening; in fact, imagine that 40 out of the 50 are severely wounded and that the other 10 have only superficial wounds."

2nd Situation
"Now imagine the same scenario, but that instead of 50 being wounded there are 300 wounded and of these only 15 have life-threatening injuries (perhaps some fit into the category of those who will die whether or not they receive treatment and others will die if they do not receive treatment). Also, assume that the battalion will be overrun in the field if the physicians are unable to quickly treat those with superficial injuries."
