What dimensions must cornrows meet according to regulations?

Cornrows must be uniform in dimension according to Army regulations. This requirement ensures that the hairstyle presents a neat and professional appearance that aligns with the military's standards for personal grooming and uniformity. Uniformity in dimensions helps create a cohesive look, which is essential in maintaining discipline and order within the ranks.

While other options may suggest aspects related to styling, they do not reflect the established guidelines for military appearance. Maintaining a hairstyle that is uniform in size helps prevent any perception of disorder and supports the overall image the Army aims to present. This attention to detail is integral to the higher standards of personal appearance expected of Army personnel.
