The commander forwards the grievance to the next authority, but remains informed. As a result of the chain of command in the military hierarchy, it is very important that the commander be aware of the fact that the person disagrees with him. That also affords the complainant and the commander the opportunity to resolve the issue informally if they can. Otherwise, it has to be handled by someone other than the commander.
