What is the size of the step taken during a half step march?

In a half step march, the size of the step taken is specifically defined as 15 inches. This distance is consistent across various military drill and ceremony practices. The half step march is used primarily to adjust one's position without significantly altering the alignment or formation of a unit. This smaller step allows for precision and control, crucial in maintaining the appearance of a cohesive unit during drills.

The specific measurement of 15 inches for a half step ensures uniformity among participants during drills, enhancing the overall visual effect and discipline of the formation. Additionally, this controlled distance is essential for performing certain movements and preparations for more complex maneuvers that may follow.
