The same four-count square as box breathing, taught for the moment your hands are shaking and you still have to perform.
Tactical breathing was developed by Lt. Col. Dave Grossman specifically for high-stakes operational environments where failure is not an option. While structurally similar to box breathing, it is taught with a combat mindset—the focus is on rapidly regaining fine motor control, decision-making ability, and visual acuity under acute stress. When the sympathetic nervous system floods the body with adrenaline, tactical breathing counteracts the tunnel vision, trembling hands, and cognitive freeze that follow. It is standard training for military special operations, SWAT teams, emergency surgeons, and competitive athletes who need to perform at their peak under pressure.
