Who was the worst superior you have had?

Brand new pinned Comms Chief in Japan. Severe lack of leadership and technical competence. Came in and immediately changed things just to change. Assigned people to supervisory positions who weren't qualified or who had demonstrated repeated technical incompetence, including cryptographic insecurities. Anyhow after a 7 month reign of terror the Dept Chief and Dept Head reassigned the Chief to MWR. I could go into many other details, but i'll leave it at that.

An MI Captain, with a Degree in Forestry, that thought that he knew more about running a complex National Level SIGINT maintenance facility than a CW3 with more than 20 years experience doing so!!!!!

In 2007 we got a new Battalion CO who was the most toxic person I have ever had the displeasure to meet. We lost a lot of good people before higher HQ replaced him.

As a Platoon Sergeant i had a 2LT Platoon Leader who would use a red pen to correct notes I wrote to myself.....While they were laying on my desk.....

LTJG (Join to see): I had a First Sergeant; who I think hated me.
GOOD MORNING, ENSIGN SHADOW; AND A VERY MERRY CHRISTMAS TO YOU AND YOURS!
-Most Sincerely, Margaret
