Most range practice consists of shooting at one or more clearly defined set targets. This basic practice is essential, but in the “real” world, a tragic, unexpected situation will most likely be cluttered and confusing. If under attack, or threatened with deadly force, chaos must be sorted out and taken into account before attempting to stop the threat, or take any appropriate action. Practicing on ever changing, decision-making targets with ID props is essential to develop the ability to quickly observe, assess, and respond to a lethal threat with a minimum of mistakes.
Practicing on a range with groups of shooters who have very different shooting experiences is educational. Perhaps you can approach your local range and ask if they’d want to participate in modifying the range with active members. If so, take turns so that one person sets up each scenario when they don’t shoot. New shooters are cycled into the scenario format and forced to sort out decision-making scenes. The outcome may present mistakes from even the best shooters.
Each shooter is aware of the necessity of solving the problem as quickly as possible, and as a result, a no-shoot target will accidentally be hit because they were not seen and were in line with the intended target, or have been misidentified as being hostile. Some shooters become flustered and confused, slow down, and sort things out at a snail’s pace so as not to hit the wrong targets. Neither approach is acceptable. Only through practice under varying and unknown conditions comes experience needed to combine quick observation, with a speedy delivery of a defensive counter stroke, and without making serious mistakes.
