A CSM can be a valuable asset to the commander, if he fits the image of top soldeir and has warrior values. I’ve seen too far too many that were simply “yes men”, political, and out for their own gain. I’ve seen more than a few that didn’t think the rules applied to them. That was my experience based on 15 years service at brigade, battalion, and company level.
Looks like old Walz was a) a Coward, B) Without honor or C) a selfish Pig. Or All three.
