Well like it or not, those serving are bound by rules on what they can say publicly and on social media (of which this is a type).....
As you know there is a world of difference between military and commercial confidentiality. Disclosing information to the enemy is vastly different to disclosing information to the taxpayer. The former is against the public security and interest the latter is most definitely in the public interest even though it may cause embarrassment to the senior officers who instituted the changes that led to the current system. It is all too easy to hide behind 'rules.'
