I have seen some nasty stuff but this stuff is what the enemy would do to you and yours and by extension others.
I recall in my Division, VN, heavy casualties brought fewer prisoners, payback.
Thus it has always been. However, while carrying out war crimes on soldiers will make them mad, nothing quite gets them vexed like seeing tortured and murdered children. Any unit that gets exposed to a bunch of that needs to be pulled off the line immediately, because they are primed to go on a rampage.
And *that* “is prejudicial to good order and discipline”.
