True story.
Many, many years ago I stormed into my boss's office â “ he was a RAdm â “ in quite high dungeon about the doings of some idiot one star out in the boonies.
The boss chuckled and said, â Å“OK, [Rusty], agreed; dumb as a bag of hammers but, did he really do any harm?â ?
â Å“No,â ? I replied, then â Å“come to think of it, I don't think they do anything, harmful or not.â ?
â Å“Exactly,â ? said the Admiral. â Å“Don't forget,â ? he said, â Å“promotion boards aren't perfect;after all you're still waiting, no? Sometimes they really drop a clanger, Brigadier So-and-so is a case in point â “ now that he's got one star we discover he's a bungling incompetent â “ so we put him in the harmless HQ, the one which doesn't do anything.â ?
I left happy, well happier, anyway ...
Back in my day, when the earth was still cooling the VCDS was the 'general manager' and the CDS's real, working deputy. The DCDS was the head of the (embryonic) joint staff â “ responsible for plans and operations.
