He had a lot of problems with his home life, but in a war, this is ABSOLUTELY the guy you want defending your country.
I am a firm believer in snipers, who are very effective in disrupting enemy operations. But the role, like several others, is one that civilians will never appreciate. This is not the fault of the men who do it.
Snipers are not alone in this, as many military elite forces can never feel free to discuss the unclassified parts of their jobs with civilians. Often when “talking shop”, the expression of horror on the face of some family member is enough to dissuade them from ever opening up again. And this even happens in peacetime.
Something ordinary and mundane to the soldier is beyond the ken of many civilians.
