The US Chairman of the Joint Chiefs has appointed a senior enlisted adviser, Command Sergeant Major Gainey, who acts as his 'eyes and ears' on all enlisted issues. As well as spending a large part of his time visiting US bases, he also meets senior military leaders of other countries. http://www.defenselink.mil/news/newsarticle.aspx?id=16003 Is this merely a ceremonial role or does it serve a genuine purpose? Does Gainey act as a cheerleader for senior US Generals or does his role genuinely benefit junior soldiers? And would the British Army benefit from such a position?
