A bad plan with good slides is better than a good plan with bad slides. Three sergeants thinking about an issue dealing with their MOS for four months and coming up with a detailed plan, is not as good as a colonel who knows nothing about their MOS or the problem thinking about it for 30 seconds. When you achieve high rank, the difference between what you know and what you feel fades away. The schools officers go to aren't any better than the schools NCOs go to. A year's hard work by the troops can be destroyed because of some minor incident that happened to the Colonel when he was a lieutenant.
Officers sit around thinking a lot.
In a vacuum. This is not a good thing. Officers think they're businessmen. This is because officers spend a lot of time trying to sell things, usually grand ideas and catchy names. Officers really do believe that a soldier is happier when he's busy, even if he's not doing what's important.
