What is the proper method to measure a step in military drill?

Measuring a step in military drill is properly done from heel to heel. This method provides a standardized approach, ensuring that all service members maintain uniformity and precision during drills and formations. By using the heel-to-heel measurement, soldiers ensure that their movements are synchronized, which is crucial for maintaining discipline and cohesion in ranks. Comparing this with other methods, toe to toe would not give an accurate depiction of the distance covered during a step, as it does not account for the full length of the foot. Shoulder width and elbow to elbow measurements pertain to spacing and positioning rather than the specific step measurement and can vary greatly among individuals, potentially leading to inconsistencies during drills. Therefore, heel to heel is the most reliable and widely accepted method for measuring a step in military drill, ensuring uniformity across different personnel.
