It’s a question we don’t ask often enough: Why do American soldiers disproportionately suffer from PTSD? We would expect veterans to report higher rates of PTSD relative to civilians, but not higher than combat troops in other countries.
And yet the numbers are striking: In Canada and Britain, close to 10 percent of combat soldiers are diagnosed with PTSD. In Israel, a country in which military service is mandatory, the rates are roughly 1 percent. Among American troops, the rates are as high as 25 percent. This is especially remarkable in light of the fact that only 10 percent experience combat.
