While I generally agree that people will most likely do what they have been trained to do, assuming the training has been thorough and there has been practice as a follow-up. it does not follow that that is necessarily always a good thing. What I am referring to here is that there may be totally unintentional side effects of training. Some of these may be difficult to avoid and might be because of the safety and management issues associated with training, especially with a large number of trainees involved. Others may be minor and completely innocent but are a reflection of other factors associated with simply shooting on a range. However, this is not something new that trainers and graduates are unaware of. Usually it probably won't make much difference.
Moreover, there will probably be different issues for people who are law enforcement officials, soldiers and plain citizens, since they are very likely to be operating under different conditions and, to one degree or another, under different rules and authorities. But mostly everything is the same.
Here are some of the things I am referring to, although mostly they have little to do with the general topic of the thread: shooting at moving targets, taking cover, what to do with an empty magazine, beginning action from other than a standing position, moving, and even choosing not to shoot. Are you required to pick up your brass or do you as a matter of choice anyway?
