What is a simple shooting exercise to develop skills? In my DH 2.0 course I instruct students to move up on a barricade and fire from standing and kneeling from both sides of the barricade. They start 4 feet away from the barricade, move into position and fire the designated number of rounds. They repeat this drill a number of times then they watch the next student perform the drill.
The technique in barricade shooting is simple. If the bad guy is targeting you stay off your cover, if the bad guy is targeting someone else rest on your cover to take a more accurate shot. Stress and adrenaline is the reason you rest on cover to stabilize your shots. If you're staying off cover aim through the barricade and and get your sights or red dot, obtain your proper stance, right foot forward staying behind your cover, then roll out by pushing up on your left toes, aim and fire. First time you roll out aim low to pick up a low lying threat or you can quick peak if you're unsure where the bad guy is . There is more to it than that such as, don't cast a shadow, sound discipline, identifying cover/concealment and more...
Students understand proper position and use of cover pretty quick. When you add a complex shooting drill involving movement, multiple firing positions, round counts or multiple targets they forget the basics, at first. Stress, competition, multi-stage courses of fire, multiple firing positions, concealed draw stroke, low-light and cold weather can all be a part of complex shooting drills. The more you shoot complex drills the better you get.
The two students in this video are advanced shooters. They can shoot accurately and can manage their handguns with no issues. The first complex use of cover drill found their skills lacking. They both looked at the target then sighted. Both their positions on the barricade were not what we had practiced. This video highlights what happens if you don't master skills.
I see this all the time in my training. These students in this video are above average shooters. I see the same thing in my law enforcement courses because gun owners or officers don't train enough to master these skills while under stress. Both these students addressed these issues after this video was taken. Awesome job guys!
