The enemy could arrive at any moment, and with the wounded, it's not just an hour we're talking about—it could be two hours, three hours, and they still wouldn't all be taken care of.
Generally speaking, the emergency measures that a field medic can take on a battlefield are limited, consisting of nothing more than stopping bleeding, pain relief, and then escorting the wounded to a frontline hospital. The key to whether some of the seriously injured can survive still depends on the treatment they receive at the field hospital.
But the Egg Bomb Squad only had five people, and among them, two had medical skills that surpassed a field medic, even reaching the level of a battlefield surgeon.
Having a battlefield surgeon around greatly increased the chances of survival for every wounded person here, of course, divine intervention couldn't save those destined to die, but for the injured who were on the brink, the presence of a doctor meant they had a much better chance of living.
