We don't take young men in the prime of youth etc, THEY volunteer. (No conscripts any more which is a good thing) It is made crystal clear to them during their training what they will probably face and what is expected of them, and that they will almost certainly be facing an enemy who play by completely different rules to them, a barbaric, violent, cruel adversary. Nobody makes anyone join the forces or makes personal stay if they clearly have problems of whatever nature which are difficult to, or can't be addressed. The whole point is that we DON'T play by Taliban rules and that hopefully we can convey that to the local population in the brilliant work done by our troops in ensuring that girls can go to school, markets can operate, clean water is available, medical care and so much more which we and others are trying to put into place. Torturing and murdering a POW is hardly conjusive to the very difficult job of convincing the locals that we are there to defend and help them. I for one am glad this came to light, if only to make sure that it never happens again as it may well not be the first incident, but let's now hope it's the last. If this man felt he was under pressure, suffering from flashbacks due to his previous experiences, or whatever may have been troubling him, he should, as an experienced senior NCO have sought the appropriate medical help, not resorted to calculated cruelty.
