Dynamic Deviation Control is a pistol shooting drill that is designed to inculcate a shooter to engage a moving target.
I have had the good fortune to be trained by some of the best military shooting instructors you can find, but I have never once seen this type of drill done on static paper targets.
When you consider the bulk of tactical pistol training occurs on non-moving paper targets this drill may make quite a bit of sense. Certainly worth trying out next time you are at the range, just be careful not to drop the basic principles such as grip, stance and sight alignment when you add movement to your gun.
Dynamic Deviation Control is certainly an interesting drill to try out when you hit the range.
