The Gulf War was amazing for the lack of casualties. At the time, I worked for a life insurance that insures mostly military people, and the investors were in a panic at the projections of thousands of our military people dying.
We lost SIX insureds. Four were combat casualties (a couple in that missile attack on the barracks in Saudi Arabia), including a car accident and a heart attack.
My kid sister and I were both active duty during the Gulf War. My uncle, a Navy vet from the early 60s, told me he was stunned at the low casualties. He said they "were likely to have more killed during peacetime exercises in his time than the whole war did." He may have exaggerated this a bit, but it's still significant.
