Which movement is the only one that starts with the right foot?

The movement that starts with the right foot is known as "right step, MARCH." In military drill, the right step is characterized by taking a step forward with the right foot first, which is a standard practice. This method maintains alignment and uniformity among ranks when performing marching drills.

In contrast, other movements such as "left step, MARCH," "forward march," and "backward march" do not initiate with the right foot. The left step begins with the left foot, forward march can start with either foot depending on the count, and backward march typically involves stepping back with the left foot first as well. Understanding this sequence is crucial for maintaining discipline and synchronization during drill movements.
