Notes:
1. The first two entries in column J are low because there are no values in column E.
2. The ratio of casualties to number serving, J, is high for the Mexican and Civil Wars due to infections.
3. The ratio of wounded to deaths, I, is high in Iraq due to suicide bombers and IEDs; e.g., car bombs.
4. Traffic accidents have killed more people in one year than any war since Vietnam.
