Postural stability during slow firing is normally considered a static action. Rapid/timed/sustained fire is considered a dynamic action.
Because of the difference, the shooter’s stance may vary from one to another. During a dynamic action the body is moving and maintaining balance may require a wider stance to accommodate the body’s motion, while a static action may have better balance with a narrower stance. The effect of recoil and follow-on shots during a static action is normally not an issue because precision firing is done one shot at a time.
