Which of the following movements in marching requires a 15-inch step?

The half step in marching is characterized by a smaller stride, specifically a 15-inch step. This movement is essential in maintaining proper formation and alignment without advancing forward significantly. It is typically used in situations where soldiers need to tactically adjust their position or prepare for an upcoming command without changing the overall formation distance from the unit ahead.

In marching, forward march typically utilizes a longer step, often 30 inches, to facilitate swift movement and forward progression. The left wheel and right face commands also involve different stepping techniques that do not specifically align with the 15-inch step characteristic of the half step. Understanding the various movements and their appropriate step sizes is crucial for maintaining drill and ceremony precision.
