In defensive pistol work we have to consider the "Plus 1" rule.
That's one more threat.
One more weapon.
One more shot. Etc.
With one more threat, you may need to go from one target to another. Most will simply swing the firearm from target 1 to target 2, but that's not really the best idea.
How close is target 2 to target 1? Are you sure the thing you saw out of the corner of your eye is a threat? What if you can't see the second threat, but you know there is another threat, but not their range to you?
For SMT, each target transition is based upon what we can see and how close your threat is to you. So in this week's Drill of the Week, we're going to work all three of SMT's target transitions.
