I've also heard that for soldiers, seeing one more death or injury can be the tipping point into PTSD.

Am I missing something, or does this follow trivially from PTSD being binary and the set of possible body counts being the natural numbers?

The thing is that PTSD is really not that binary, like many mental illnesses, it has a wide range of symptoms and severity levels. What Nancy is talking about is how one death can push one drastically over, skipping much of the middle range where it might be ambiguous if one had symptoms severe enough to be diagnoseable. (Disclaimer, while I've heard the same sort of things NancyLebovitz is talking about, I'm not aware of any studies actually supporting this.)

Got it. I was previously having difficulty making that belief pay rent.
