A wounded combatant who could benefit from medevac is no longer a (edit: combat) asset to their fellow combatants, but is someone who may need one or more other people to try to keep them alive, or more people to carry them to a safer location. Their wounds or injuries may prevent the group from moving as easily. In the cold calculus of ground warfare, a wounded combatant in the field is more valuable to the opposition than a dead combatant precisely because a dead person needs less support from their fellows. Rapid medevac has changed the historical wounded:killed ratio from about 3:1 to about 4:1 in recent US ground wars. Getting a wounded combatant to definitive medical care in the first hour after they are injured makes a huge difference in outcomes, which benefits troop morale.
