“2212. TO CHANGE STEP. The purpose of this movement is to change the cadence count without changing the rhythm of the cadence.
- The command is “Change Step, MARCH.” It may be given while marching at quick or double time, marking time, or double timing in place. The command of execution is given as the right foot strikes the deck.

- a. On “MARCH,” take one more step, 30 or 36 inches, as appropriate.
- b. As your right foot comes forward to the next step, place the toe near the left heel and step out again with the left foot. This changes the cadence count, but not the rhythm.
- While Marking Time
- a. On “MARCH,” lift and lower the left foot twice in succession.
- b. The second time it touches the deck, raise the right foot and continue marking time.
- While Double Timing in Place
- a. On “MARCH,” hop twice on the left foot.

The Air Force
“The command is Change Step, MARCH. On the command MARCH, given as the right foot strikes the ground, the airman takes one more 24-inch step with the left foot. Then in one count, place the ball of the right foot alongside the heel of the left foot, suspend arm swing, and shift the weight of the body to the right foot. Step off with the left foot in a 24-inch step, resuming coordinated arm swing. The upper portion of the body remains at the position of attention throughout.”
