The step barricade: I am not able to take credit for the design of this obstacle. Viking Tactics posted their design and I made a couple of simple modifications to the ones we use now. Click above to link to their site and find their plans.
This simple drill allows shooters to acquire a mental picture of how to align their sights, hold their firearm, body position, gear placement, reloads (from nonstandard positions) and shows how safety can diminish as your physical and mental fitness diminish.
This drill is as much about firearms safety as it is about marksmanship and positional shooting.
Every portion of this barricade can be directly or indirectly translated into positions you can find yourself in while not on a flat range.
