Our undershirt vests expired awhile ago and I bought my own ceramic vest as ours were only lv2 to begin with. This allowed me to add rifle protection by throwing that vest on in an as needed basis. We had an all hands respond call for a student with a gun inside an eating facility threatening to shoot an employee. I work for a private college, I responded and was second on scene threw on vest and we took care of the call. Another officer who has a blatant dislike for me took it upon himself to go to the Chief about my vest knowing full well our Sgt didn't care. I get called into the office today and told that I need to ensure that all patches and badge are displayed while wearing said vest. I said not a problem that was already being done, escaped from the office and thought I was set. Get another phone call stating that the Chief explicitly forbade my use of the vest for any reason and do not let it ever enter any of our vehicles. FML seriously!? I've got a wife and a kid coming in 3 weeks.
