That is DnC. Heck, my unit can't do any of that. We have to get a class for Change of Command to remind us. My buddy Soto's unit does DnC once a month for a day.
I'm extremely impressed at how crazy good they are.
At one of my units we did an hour of D&C for PT one day per week. Marching for any length of time is fairly physically demanding if you're doing the correct 30-inch step @ 120 steps/minute (300 feet per minute/18,000 feet per hour, or about 3.5mph.) We ALWAYS had to practice for a couple days prior to any of the bigger change of command ceremonies, because left turns & right turns just weren't things you normally did in day-to-day military life. The troops on the outside of an 8-column formation really had to step it out in order to keep the lines straight.
I remember during basic training, we were maybe in week 2 and everyone had finally learned to stay in step and march from the waist down, so we were being taught stuff beyond the normal "column left, MARCH", "column right, MARCH", "half step, MARCH", etc. Our drill sergeant had spent most of the morning teaching us "rear, MARCH", in which the preparatory command ("rear") is given when the right foot strikes the ground, and the command of execution ("MARCH") is given the next time the right foot strikes the ground. The left foot takes an additional step now, becoming the leading foot, and the soldier pivots 180 degrees to the right when the left foot lands. The left foot is now the trail foot and immediately takes a step, the maneuver having taken 1/2 second when done right (120 steps per minute.)
Anyway, the company 1st sergeant came by to check on our training, and our drill sergeant told him what he'd been teaching us. "Platoon, attenTION!" he bellowed. "Right, FACE! Forward, MARCH! 1st squad to the rear, MARCH! 2nd squad to the rear, MARCH! 3rd squad...!" Well, we F'd it ALL up BADLY, and were smoked to a truly epic extent as a result. One of the worst things you can do in the military is to make an NCO look bad to his boss, and we'd done just that.
