I agree with you gracesmum, after WW1 many many lives were shattered for an umpteen number of reasons. My Grandfather was went through it in the Light Infantry as a volunteer and was both shell shocked, not severely, and gassed, again not severely. Neither he nor my stepfather ever talked of their experiences, maybe to their wives, but not to us! However, both in WW1 and WW11 the majority of the combatants (including them and my father) were conscripts/volunteers, and, by today's standards, not particularly well trained, and certainly NOT prepared for the horrors of war. The armed forces are now manned by professional personal who join of their own free will go through rigorous training with the opportunity to drop out at any stage during that training, they are made well aware of what they are likely to face in EVERY respect and how they MUST behave in every circumstance, both for themselves and for the welfare of their comrades in the face of a merciless enemy who they know could retaliate with extreme barbarity. They also have the benefit of trained, sympathetic people to help them at all times should they need it, whatever that help maybe. So a very different 'playing field' than the one in which our forebears had to do their fighting. We know too that this was not only calculated cruelty by a senior NCO, but that two other junior ranks were actually encouraged to behave in like fashion so I'm sorry to sound harsh, but I see no mitigating circumstances here.
