How must the male haircut be styled according to regulations?

The styling of male haircuts according to Army regulations requires that hair be maintained in a neat and professional manner, specifically with a tapered appearance. This means that the hair should gradually shorten from the top of the head to the sides and back, maintaining a clean and polished look that is appropriate for the military environment.

A neatly groomed appearance is essential as it reflects discipline and attention to personal appearance, which is critical in a military setting. The tapering not only keeps the haircut within the established guidelines but also promotes uniformity among Soldiers, reinforcing the Army's standards of professionalism.

In contrast to the other options, long and flowing hairstyles do not comply with the requirements for military haircuts, as they can appear unkempt and are not practical for Soldiers in uniform. Short and uneven cuts do not present the disciplined appearance expected from military personnel, and styles with excessive volume do not align with the standards set for grooming, as they can detract from the uniformity and neatness required.
