One other aspect from one of the WWII soldiers who rotated home after 3 years of combat said of the home coming that the thing that affected him the most was the silence and lack of noise.
I agree with BAR on the matter that hopefully better systems are in place for the returning soldiers as the conflicts we have today remind me of what issues faced the forces in VN as who was Charlie now days its who is the terrorist and whilst they operate out of residential areas sadly civilians are being killed which no allied or NATO soldier would want.

My Brother in law a returned VN vet counselled for a fair while but the strain on him helping these chaps get over their VN tour/s took a toll on him eventually he had to give it away as it brought to many ghosts out of the closet and memories that he would rather stay buried he did not want to leave his mates but had to for his own sake.
