You are confronting an armed suspect, no cover available. He faces you, with his gun at his side, pointed at the ground. Your gun is aimed at him and you’re ready to shoot. He ignores your commands to drop his weapon. Are you justified in pulling the trigger before he makes any move to point his gun at you? On any shooter, you need fast reflexes to adapt to a rapid and fast-paced environment. Reaction time decides who wins and who loses. To build your reaction time, practice the more complex moves with a friend.
