Wounded-To-Killed Ratios

Some wounded-to-killed ratios drawn from my upcoming book War by Numbers: Understanding Conventional Combat. I have an entire chapter on the subject in my book (Chapter Fifteen: Casualties). This first chart is from Trevor Dupuy’s Attrition:

A table I created to compare U.S. Army and U.S. Marine Corps ratios:

table02

A tabled I created looking at the U.S. units the I Corps area of Vietnam. This is after the Tet offensive, and these units are operating side-by-side and listed from north to south. The 1st Bde, 5th ID was up at the DMZ while the 23rd (Americal) Division was in the southern part of I Corps:

table03

And finally the ratios from Iraq and Afghanistan. Note these are higher ratios compared to what is reported in the previous post for the Iraqi Army and the Peshmerga.

This is why the Iraq Army and Peshmerga wounded-to-kill ratio in the previous post caught my attention.
