One CO and a series of Command Master Chiefs have been relieved in the last 3 weeks:

1. CMC of the Navy Medicine Training Support Center for a DWI and then failing to report the DUI. (not sure if the failure to report the arrest was for his security clearance -- which is required for all arrests, or to the chain of command.)

Navy Times:

2. CMC of Strike Fighter Squadron 86 for violating the Department of the Navy's sexual harassment policy by making sexually suggestive and possessive comments to junior enlisted sailors.

Navy Times:

3. CMC of Helicopter Maritime Strike Squadron 70 was relieved of his duties Tuesday due to unsatisfactory performance over an extended period of time.

JAX Business Journal:

4. The commanding officer of USS COWPENS and the ship's CMC were relieved due to loss of confidence in Gombert's and Keeton's ability to effectively lead and carry out their assigned duties.

Navy Times:

#1: No brainer, should be relieved.
#2: No brainer, should be relieved.
#3: "unsatisfactory performance over an extended period of time", I am not sure of the specifics. I do not think a Master Chief gets into the CMC program without demonstrated superior performance (the best of an already select group.) My inclination is that the "over an extended period of time" part means there was some counseling from the CO over time that was not heeded.
#4: COWPENS just returned from deployment, there was an inspection and they failed. I have heard this was related to the maintenance programs. 3M is a monster (INSURV being the largest beast there is).

#1 & #2 genuinely sadden me, since we should be smarter than this.
#3, makes me wonder
#4 makes me curious about the willingness to report issues outside of the ship. I had a CO once who was somewhat averse to CASREPs and was adept at using connections to get parts and assist teams to get maintenance issues fixed. I had another who flexed the CASREP system to the max. In the long run between the two I prefer the latter -- use the system. In the long run it doesn't hide issues and over time when you see the same piece of equipment with 5 or 6 CASREPs in one year you are feeding a bigger database of issues than exists within your own lifelines.

At the same time ... the vast majority of Commanding Officers, Command Master Chiefs, and other senior leaders are getting it right ... that just doesn't make as much news.
