Like with many things in the UK, the help is there but you have to know how to go about getting it.
My Father fought all through WW2, got out of Dunkirk at the start, then later, went through the N. Africa campaigne, into Scicily and then Italy. At the end of the seven years, nearly five of those without getting back to the UK, he was given £75 gratuity and a demob suit!
There was no such thing as PTS though, after WW1 she'll shock was beginning to be recognised. (Many soldiers who suffered it were shot as deserters or cowards and a few years ago most were 'forgiven' and the black mark against them erased)
I know my Dad would never talk about the war as such. He told many very funny amusing things that happened and once said to my questions that they were either bored stiff or petrified.
Even so many men were altered by what they saw and did, they had no help at all and had to cope the best they could.
Since war has changed stress levels have to be higher. Not knowing of a child,woman or anyone walking towards a camp is a moving bomb has to be stressful.
The awful thing is that in the forces the average soldier has to take command and becomes 'institutionalised' so coming home to chivvy street, having to make decisions when there are pictures flashing through your mind has to tell sooner or later.
It seems from what I have read and researched that the US did not learn anything from the Vietnam war over treatment of its soldiers and, Britain is close behind.
I salute those in the forces and thank them past and present. It were not for them then none of us would be as we are today.
God Bless them all and please help them in times of trouble.
