I just found a little vid from Magpul that coincides nicely with my last tactical preschool lesson, where I discussed developing a scanning method for target engagement.
What Magpul instructors have done is design a drill where a shooter is shown two photos of faces. The shooter then runs down range where he has to engage a series of targets with various faces, two of which match his “hit list”. I think that an interesting twist would be to tell the shooter “these are the bad guys, shoot one or both of them if they are a threat” then have one of both of the targets displaying weapons. Not only would the shooter have to find the bad guys, he would have to figure out if he was authorized to use deadly force as well. Mix targets of cops displaying weapons into the crowd to really add some fun.
