Can anyone share experience with what kind of testings are required (if any) and how you became a firearm instructor for your agency? Did your agency send you to armorer's schools? I am going to be submitting my letter through the ladder in hopes of becoming one of our own instructors. It's new to me so I want to get a little bit of expert insight. Any info is of great help with much appreciation! Wanna kill these ads? We can help!
