Manning have none of the levers that can make the differences required. They have tacitly admitted that. Everything these days requires tri-Service committee buy in. The USAF have given a huge retention incentive out to keep their people from walking out of the door. For that they had to go to Congress.
For this to be fixed it needs support all the way to the very top of Government and Treasury.
Good luck with that - we will have to be on our backsides, unable to function, for anything to be done. Until we get to that point (and we are not there yet) it won't get beyond OF5/4/3 level measures.
