When I hear of things like Mozambique drills I think of stationary paper targets being faced by shooters that are waiting for the beep or the shoot command of an instructor.
Agreed. I was thinking the same thing when I read the two to the chest, one to the head routine. I've shot it thousands of times. Works great on the flat range during daylight at seven yards with a target that doesn't move or shoot back. I can't really even visualize it in a real deal since I'll be moving, he will be moving, along with the many other possibilities not found on a typical range.
