Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

The active shooter drill is the same everywhere. I'm a civilian employed at Keesler AFB. We have the drill at least
once per year. Our instructor is a retired Chief Petty officer. He said Military and Civilian training are the
same. Run first hide 2nd and fight as a last resort.
When I taught civilians Active shooter, I didn't tell them what order they should run, hide, or fight in. Every circumstance is different. I told them to silence their cell phones, lock doors, get as close to the floor as possible. I didn't want someone running when hiding was the best option and vice versa.
