How far down are sideburns authorized in the Army?

In the Army, sideburns are authorized to extend to the level of the jawline. This standard is part of the Army's grooming regulations, which aim to maintain a professional appearance among service members. Allowing sideburns to be trimmed to the jawline ensures a neat and uniform look while still permitting soldiers to express some individual grooming preferences. Maintaining this guideline is essential so that sideburns do not interfere with helmet wear or other military headgear, which is another aspect of the Army's uniform and grooming standards.
