Military headgear regulations follow one baseline across every branch: wear your cover outdoors when you are in uniform, and take it off when you go inside. The details, from how a beret sits above the eyebrows to whether you salute without a cover on, come from service-specific instructions like Army Regulation 670-1, Department of the Air Force Instruction 36-2903, and the Navy Uniform Regulations, layered over shared Department of Defense standards.
When To Wear It, When To Take It Off
Outdoors in uniform, headgear stays on. The Army, Air Force, Space Force, and Navy all treat this as the default.1Department of the Army. AR 670-1 – Wear and Appearance of Army Uniforms and Insignia The Space Force follows the Air Force approach and requires headgear outdoors unless the installation commander has designated a specific area as a “no hat” zone.2U.S. Space Force. SPFI 36-2903 – Dress and Personal Appearance of Space Force Personnel Those zones are common around child development centers, flight lines, and other locations where a cover creates a safety or practical concern.
Once you step indoors, headgear comes off. Navy regulations state this plainly: personnel remain uncovered indoors at all times unless directed otherwise for a special event. The exception is being under arms. If you are wearing a duty belt or carrying a weapon, you stay covered indoors to signal your active operational status. Even then, the Navy requires armed personnel to remove headgear when entering dining areas, medical facilities, or spaces where religious services are being conducted.3MyNavyHR. Navy Uniform Regulations – Chapter 1 – 1101 General Information
Vehicles and Commercial Travel
Headgear is not required inside a privately owned vehicle. That covers cars, motorcycles, and convertibles. The same applies to public transportation: you can remove your headgear on a subway, train, bus, or commercial airplane.1Department of the Army. AR 670-1 – Wear and Appearance of Army Uniforms and Insignia Military vehicles during official convoys or formations are different, and the outdoor protocol generally applies. Command leadership keeps authority to modify headgear rules during training exercises or field environments where safety equipment takes priority.
How Each Cover Sits on the Head
Patrol Caps and Garrison Caps
The patrol cap and garrison cap sit squarely on the head with the front edge resting about one inch above the eyebrows, roughly the width of two fingers. The brim or edge stays parallel to the ground. Tilting the cap back, pushing it to one side, or letting it ride low over the eyes falls outside regulation and will get flagged during inspection. The goal is a clean, level profile with the face fully visible.
Berets
The beret is where many service members get caught during inspection. The headband sits straight across the forehead at the same one-inch mark above the eyebrows. The flash, which is the organizational insignia sewn onto a stiffener on the left front, must sit directly over the left eye.4Department of the Army. DA Pam 670-1 – Guide to the Wear and Appearance of Army Uniforms and Insignia The excess material drapes down over the right ear, reaching at least the top of the ear but no lower than the middle. The adjusting ribbon at the back is cut and tucked inside the edge binding so nothing dangles.
Getting the right drape usually takes work before the beret ever goes on. Many service members shave the wool with a razor to reduce bulk, then use hot water or steam to mold the fabric to the head. If the material bunches or rides high, the beret has not formed to the shape of the head, and that is exactly what inspectors check. The Air Force takes a similar approach and requires the cloth flash to be sewn to the center of the stiffener, positioned a quarter inch above and parallel to the headband.5U.S. Air Force. DAFI 36-2903 – Dress and Personal Appearance of Air Force Personnel
Hair That Fights the Cover
Hair that is too long or too bulky pushes the cap away from the scalp, keeps it from sitting at the correct height, or distorts the shape of a beret. Branch regulations require that hairstyles not interfere with the proper seating of any headgear, including berets, garrison caps, patrol caps, service caps, and combat helmets.4Department of the Army. DA Pam 670-1 – Guide to the Wear and Appearance of Army Uniforms and Insignia This gets checked at routine inspection.
Cold Weather and Branch-Specific Covers
When temperatures drop, the knit watch cap replaces the standard patrol cap or garrison cap. The Navy authorizes the watch cap when the appropriate authority determines that cold weather conditions could cause personal injury if the cap is not worn. There is no fixed temperature threshold in the regulation; the decision rests with local command.6MyNavyHR. Cap, Knit (Watch) The watch cap is also authorized with the physical training uniform when weather calls for it.
The Space Force recently authorized the OCP boonie hat for garrison wear at the discretion of the unit commander. Officers may display rank insignia centered on the front; enlisted members wear only a name tape on the back.2U.S. Space Force. SPFI 36-2903 – Dress and Personal Appearance of Space Force Personnel Each branch maintains its own authorized list, and wearing headgear assigned to a different branch or unit is a uniform violation.
How Headgear Changes the Salute
Whether you are wearing a cover affects when and how you salute, and the rule splits along service lines in a way that trips people up during joint operations.
The Army and Air Force require service members to salute superior officers outdoors whether covered or uncovered. The presence of headgear is not a prerequisite for the hand salute in these branches. Indoors, personnel generally do not salute unless reporting to a superior officer or participating in a formal indoor ceremony.7U.S. Army. Salutes, Honors, and Courtesy – AR 600-25 Personnel under arms indoors salute with whatever weapon they are carrying, using the salute prescribed for that weapon.
The Navy takes the opposite approach. Navy personnel do not salute when uncovered, except in situations where failing to do so would cause genuine embarrassment or misunderstanding. If you are outdoors without a cover and encounter a superior, the standard response is to come to attention rather than render a hand salute. The Marine Corps follows the same convention. Know this before you find yourself at a joint installation.
During the national anthem or a military funeral, the rule tightens. Outdoors and covered, you render a sustained hand salute until honors conclude. Outdoors and uncovered in an Army or Air Force context, you still salute. Navy and Marine personnel in the same situation stand at attention.
Religious and Medical Accommodations
Federal law permits service members to wear items of religious apparel with the uniform, provided the item does not interfere with military duties and meets the standard of being neat and conservative.8Office of the Law Revision Counsel. 10 USC 774 – Religious Apparel Worn While in Uniform In practice, this covers turbans, hijabs, yarmulkes, and similar head coverings. The item must be in a color that blends with the uniform and cannot prevent proper wear of protective equipment like helmets or gas masks.
The process is set out in Department of Defense Instruction 1300.17. Requests that fit within existing uniform standards get handled at the lowest appropriate command level. Requests that require a waiver of branch-wide policy get forwarded up to the Secretary of the relevant military department.9Washington Headquarters Services. DoDI 1300.17 – Religious Liberty in the Military Services A detail many service members miss: you must keep complying with the standard policy while your request is pending. You cannot start wearing the accommodation before receiving approval.
If your request is denied, you can appeal to the next level in your chain of command above the officer who made the decision. The DoDI does not set a specific timeline for how quickly the appeal must be resolved, leaving that to each branch’s implementing regulations. A denial by the Secretary of the Military Department is final, with no further administrative appeal available.9Washington Headquarters Services. DoDI 1300.17 – Religious Liberty in the Military Services
Service members with documented scalp or skin conditions that prevent the wear of standard headgear can receive a medical profile authorizing a deviation. In the Air Force, a medical provider recommends the profile, but it only becomes effective after the unit commander approves it. Commanders have up to seven days to approve or disapprove and can consult with the member’s medical provider about any concerns.10U.S. Air Force. DAF Updates Medical Shaving Profile Guidance Other branches follow similar frameworks where medical authority recommends and command authority approves.
Military Headgear With Civilian Clothes
Across all branches, you do not mix distinctive military uniform items with civilian clothing. Headgear with unit insignia, rank devices, or branch-specific design features falls squarely into that prohibition. The Marine Corps regulation puts it directly: no part of a prescribed uniform, except items not exclusively military in character, may be worn with civilian attire.11Marine Corps Training and Education Command. FMTB Civilian Attire Policy Watch caps are specifically listed as an authorized exception for Marines. Distinctive covers with insignia are not.
Federal law also restricts civilians from wearing military headgear. Under 10 U.S.C. § 771, no person outside the armed forces may wear the uniform or any distinctive part of it, which includes branch-specific headgear with insignia.12Office of the Law Revision Counsel. 10 USC 771 – Unauthorized Wearing Prohibited This applies to items that are recognizably military, not generic clothing that happens to resemble a military style.
Retired officers may bear the title and wear the full uniform of their retired grade, including headgear, under 10 U.S.C. § 772.13Office of the Law Revision Counsel. 10 USC 772 – When Wearing of Uniform by Persons Not on Active Duty Authorized The same prohibition on mixing applies to retirees. Air Force retiree guidance specifically calls out cap devices as an example of distinctive uniform items that cannot be worn with civilian clothing.14Air Force Retiree Services. Retiree Uniform Wear If you are wearing the uniform, wear the complete uniform with the correct headgear. If you are in civilian clothes, leave the military cover at home.
Consequences for Getting It Wrong
Most headgear infractions get handled with verbal counseling or a written record long before they reach anything formal. Minor uniform violations do fall within the range of offenses that commanding officers can address through non-judicial punishment under Article 15 of the Uniform Code of Military Justice, which allows penalties from extra duty and restriction to forfeiture of pay, all without a court-martial.15Office of the Law Revision Counsel. 10 USC 815 – Art 15 Commanding Officers Non-Judicial Punishment The practical takeaway is simpler than the regulation stack: wear the right cover, wear it correctly, and take it off when you go inside.
