Another shooting and moving drill video from Tactical Rifleman called the One Leg Agility... "This week Rob takes us through another Agility Drill. This one is called the 'One Leg.' As Rob says, it’s not meant to be tactical, but rather more of just an exercise drill (Shooting & Moving). As with the other agility drills; start slick, then add kit. Start slow, then add more speed. Start close, and then move farther out.
