To be ready to respond quickly to a crisis situation, I carry a “Go Bag.” Inside of it are extra rounds (already in magazines), extra first aid items, extra charged radio battery, extra flashlights, flexi-cuffs, matches, one MRE (meal ready to eat), binoculars, extra set of gloves and a window punch. The bag was set up mainly as an active shooter response bag, but now I use it for any critical incident response. It has everything you need for a brief amount of time...just grab and go.
