I think the most important man in a unit is the RSM. He should know what's going on in the battalion or regiment through his CSMs/SSMs and setting the standard.Hence the graduate recruitment thing apparently. It seems the airborne powers that be were worried that the incidents Bramley would later describe were indicators that the ‘green-eyed boy’ thing had also permeated the junior officers. They had become, in effect, ‘part of the problem’ and apparently it was felt that slightly more mature graduates would be able to resist the pressure.
Old General Dave Morrison may be a bit woke. but he got it right when he said "the standard you walk by, is the standard you set.
