I had a manager once who was ex-Navy (electronics specialist, not an officer). He approached management with a hard-nosed Type A mentality. He definitely went after people who he saw as coasting, and in some cases that was undoubtedly justified. He got results but there was also a lot of churn. He also made the mistake of taking too much on himself because he saw that as easier than the hard work of understanding and motivating people. After a while the atmosphere fell into bad faith, cynicism, and lack of trust. After some span of time he was moved to a position that kept his rank but removed his reports. The churn got so bad that upper mgmt had to deal with it, and HR also got involved. I think he's working at Amazon now.
