You can just wear the top 3. not everyone chooses to wear all awards received. Bill has a great point. I too saw too many examples of individuals intent on making rank, achieving command, etc; and unwilling to push back on bad ideas.

It is hard enough to do the job, but competing to make advancement or promotion, always a specter of next assignment options, not to mention being 'voluntold' to do "collateral" duties piled on top of the main job; it can be very hard to "speak truth to power", and those in power rarely give one credit for that. Too many instead make life miserable for those who stand up to them. One of the challenges of being in the military is the inherent conflict of how to challenge poor leaders and policy when it can kill progression of your career. And you can't just quit, as you have defined periods of service, and certain levels you must reach if you are allowed to stay to get a pension.
