Your observations need to be noted by others here - nobody knows how they will react until the situation is upon them - very true of myself - and all we can do is prepare best we can. I’ve seen many assert how bad-ass and cool they would be - hope they never have to find out because it might cause a catatonic reaction when their ego is deflated.
You and I are on the same page. We do have combat veterans on here, and I expect they have some idea how THEY will handle it.
