The authority to determine an acceptable medical beard’s length and appearance comes from the medical professional who assesses the condition and documents it in a Medical Profile. That profile, created by the appropriate medical authority, specifies what facial hair is permissible to accommodate the medical condition while still meeting safety and uniform requirements. The unit commander enforces AR 670-1 based on that profile, but does not independently set the appearance. The other offices handle processing and legal matters, not the grooming standards themselves.

The key idea is that wearing the Army uniform during public speeches, interviews, picket lines, marches, rallies, or other public demonstrations is tightly controlled to prevent the uniform from being used to imply Army endorsement of a cause. Because of that, approval must come from a high level in the chain of command to ensure consistency with Army policy and proper judgment about whether such appearance is appropriate. The correct authority is the first O-5 in the chain of command. This means the battalion commander (or the next senior officer who is an O-5 in your chain, depending on your unit’s structure) must authorize it, and that authorization is typically in written form. This higher-level review helps ensure the appearance aligns with Army standards and prevents misuse of the uniform in political or public contexts. Lower-level commanders (like a company commander) or other immediate supervisors aren’t the required approvers because the policy assigns this responsibility to the first field-grade officer in the chain to maintain consistency and authority across the force.

Sideburns are kept short to maintain a neat, uniform appearance. The limit is the bottom edge of the opening of the ear. Keeping sideburns at or above that point ensures they don’t extend onto the lower part of the face or neck and stays consistent with Army grooming standards. So if the hair reaches the bottom of the ear opening, it’s compliant; extending below that point would not be. The other boundaries (ear lobe, jawline, neck) would allow longer sideburns and are not the standard used here.

The rule being tested is that hair must be neatly groomed and contained within the collar when wearing the uniform. For medium length hair, compliance means the lower edge of the hair does not extend beyond the lower edge of the collar. It may touch the collar line but cannot hang below it. This keeps a uniform, professional appearance and prevents hair from interfering with uniform fit or safety gear. If hair extended past the collar, it would not meet the standard.
