Use timing and cover while running to your advantage. For example, if the assailant is changing his magazine, this is a good opportunity to flee. When doing so do not run down the center of a hall or pathway, but bound from cover point to cover point, if available. Also understand that the above walls that we routinely see in homes and buildings are NOT cover. They are mere concealment and will not stop bullets from hitting you. Examples of cover are solid concrete pillars or walls, or should you be outside (or in a parking garage) engine blocks or wheel wells on vehicles. Either will do the trick. However, unfortunately sometimes there is no good cover available. Use speed and concealment to get off the ‘X’ and live to fight another day.
