Because troops may not follow an officer they don't trust and respect. When I was serving, I once came across a unit who didn't respect their commander. And the unit was pretty fucked up as a result. They weren't effective, there were whispered jokes about him, and people were showing up late & leaving early. If we had gone to war, there was a good chance that many unit members would have found ways to avoid serving under him. His boss at the Wing/Group level should have pulled his ticket and replaced him. The phrase commonly used for this is "Loss of trust and confidence in their ability to lead".
