Remember, firearms training is taught in three stages. First is safety - thinking safety and acting in a safe manner. The second stage is accuracy. Now we begin to apply the basic fundamentals of marksmanship training. Finally, there is speed.
Speed is a result of repetition.
The more that you do a task correctly, the quicker you will become at doing that task. It should not be tactics, for every officer should think tactics as a part of everyday officer safety. Advanced is probably just doing it better, faster, and with the same high degree of safety. Add to the accuracy. If so, we would like to hear from you.
