COs and down. And yes, it will be difficult, damnably so.Ask 2* permission to work weekends (assuming that you can find a 1* to ask the question) or work late without question, what do you think is going to happen? I think you're saying that COs should be accountable for their actions, but in reality it is very difficult to implement, though 360 reporting would be a good start.
Will it be any more difficult than managing with the ongoing retention crisis? Will it be any more difficult than attempting to recast the Army into the shape required for the next war quickly and with minimal casualties?
Why is "it will be really difficult?" a reasonable excuse?
