I agree that historically the injury to death ratio in war was 3:1/4:1.

With 21st C medicine, however, that tends to be much higher.
According to the Belford Centre Harvard University, that is more likely
to be 10:1-17:1.

"This is especially true for advanced democracies such as the United States. Consider that the typical ratio of those wounded to those killed in conflict has historically hovered around the 3:1 mark. With recent medical advances, however, the U.S. wounded-to-killed ratio today ranges anywhere from 10:1 to 17:1".
