Army Service Uniform

The Army Service Uniform (ASU) is the standard service uniform of the United States Army, serving as a versatile dress option for semi-formal, formal, and ceremonial occasions while providing a professional appearance for office and business environments.^[1] It consists of a single-breasted coat, belted trousers or slacks, a long- or short-sleeve shirt, and accessories such as a black four-in-hand necktie or turtleneck, all in Army Blue shade 450 or 451, made from a durable 55% polyester and 45% wool tropical-weight fabric.^[1] The uniform includes distinctive elements like gold braid on the trousers for officers and non-commissioned officers, service stripes denoting years of service, and overseas service bars for deployments.^[2] Introduced on August 20, 2008, the ASU was developed to replace the Army Green Service Uniform, which had been in use since the mid-1950s, as part of broader Army transformation efforts initiated in 2004 to modernize and streamline uniform options.^[2] Derived from the longstanding Army Dress Blue Uniform, it features a wrinkle-resistant, athletic-cut coat for improved wearability and includes updated insignia such as combat service identification badges and shoulder-loop distinctive unit insignia.^[1] Initial fielding of new ASU items began in July 2009, with mandatory possession required for all soldiers by October 1, 2015, at an estimated cost of $140–$200 per set, supported by increased uniform allowances for enlisted personnel.^[2]^[3] As of 2025, the ASU remains the primary service uniform but is undergoing a phased transition to the Army Green Service Uniform (AGSU), which was approved on November 11, 2018, and began fielding in July 2020 to evoke the Army's World War II heritage while serving as the new everyday business attire.^[4] All soldiers must possess an AGSU by October 1, 2027, after which the ASU will shift to an optional role exclusively for formal and ceremonial events.^[4] This change aims to enhance professionalism and readiness, with the ASU's black accessories, such as windbreakers and overcoats, continuing to support its ceremonial utility during the interim period.^[1]

Purpose and Overview

Role in the US Army

The Army Service Uniform (ASU) serves as the primary non-combat uniform for U.S. Army personnel in garrison environments and official capacities, worn during office duties, public events, and formal ceremonies where the Army Combat Uniform (ACU) or Operational Camouflage Pattern (OCP) would be inappropriate.^[5] It functions as both a service uniform for everyday business attire in non-field settings and a dress uniform for ceremonial occasions, with the service variant emphasizing practicality for routine garrison tasks and the dress variant incorporating formal elements like full medals for parades and official functions.^[5] Introduced in 2008 to replace the green service uniform and modernize options as part of 2004 transformation efforts, the ASU was designed to standardize uniforms and provide a professional appearance.^[2] This uniform replaced the older Army Green Service Uniform (Class A greens), which was phased out by October 1, 2015.^[6] The Army Blue Service Uniform, a key ASU variant, handles formal dress functions like awards ceremonies and state events, while the Army Green Service Uniform (AGSU) has been reintroduced for service duties to evoke historical professionalism.^[7] All soldiers are required to possess the AGSU by October 1, 2027, as it becomes the mandatory service uniform, ensuring uniformity and readiness for professional engagements across the force.^[7] This mandate supports the ASU's overarching role in maintaining discipline and a polished appearance during non-operational duties, with possession enforced through clothing bag allowances and purchase specifications.^[5]

Design Principles

The Army Service Uniform (ASU) is designed with core principles emphasizing durability, formality, and tradition through the use of wool or wool-blend fabrics, typically a 55 percent polyester and 45 percent wool blend in serge, tropical, gabardine, or elastique weaves weighing 9 to 16 ounces. The Army Green Service Uniform (AGSU) uses a 55 percent polyester and 45 percent wool gabardine weave, with the coat at 8.7 ounces and trousers at 6.8 ounces. These materials provide a structured yet resilient construction suitable for professional wear while evoking the timeless formality of military attire.^[5]^[1] Conservative cuts, featuring tailored jackets that fit easily over the chest and shoulders with slight curves at the hips, high-waisted trousers with a modest break, and knee-length skirts, draw inspiration from historical uniforms to maintain a dignified silhouette that balances aesthetics with practicality.^[5] Gender-neutral adaptations ensure inclusivity and functionality, offering options such as slacks or skirts for female personnel alongside maternity tunics, all prioritized for modesty, proper fit, and ease of movement. Guidelines specify loose, non-tight constructions—such as coats descending to the hips without restriction, adjustable waistbands, and skirt lengths between 1 inch above and 2 inches below the knee—to promote comfort during daily duties while upholding professional standards; sheer, skin-complementary stockings and closed-toe pumps further support modesty without patterns or excessive ornamentation.^[5] These elements reflect a commitment to equitable design across genders, allowing for body configuration variations without compromising the uniform's authoritative presence.^[5] Color schemes reinforce the uniforms' service and dress roles, with olive drab greens (heritage green 564) for the AGSU service variant, midnight or dark blue (450/150) for ASU dress occasions, and tan shirts (heritage tan 566, 75 percent polyester/25 percent wool) paired with matching ties or neck tabs to create a cohesive, understated palette.^[5] Modern designs incorporate sustainability and cost efficiencies, such as machine-washable components introduced in the 2020s AGSU reforms, which use polyester-wool blends treatable in cold water on a gentle cycle to reduce maintenance expenses and environmental impact compared to dry-clean-only predecessors.^[5] This evolution briefly nods to WWII-era "pinks and greens" influences in the AGSU's heritage styling, prioritizing enduring functionality over fleeting trends.^[5]

Historical Development

Origins and Early Evolution (Pre-1950s)

The origins of the Army Service Uniform trace back to the late 19th century, when the U.S. Army sought more practical attire for field service amid expanding overseas operations. In 1899, khaki cotton uniforms were officially adopted to replace the traditional dark blue wool garments, which had been standard since the Revolutionary War era but proved impractical for campaigns in tropical climates like the Philippines and Cuba during the Spanish-American War. This shift marked a pivotal move from parade-focused dress to functional field wear, emphasizing durability and camouflage-like earth tones over ceremonial aesthetics.^[8]^[9] From 1902 to 1917, the Army standardized olive drab wool service coats for winter wear and khaki cotton uniforms for summer, reflecting lessons from colonial conflicts and aiming for year-round versatility. Officers retained access to blue dress uniforms for formal occasions, but the entry into World War I in 1917 prompted the complete elimination of blue variants across all ranks to streamline production and focus on utilitarian designs suitable for mass mobilization. These olive drab ensembles, often paired with campaign hats, prioritized comfort and inconspicuousness in combat environments over the elaborate styling of prior eras.^[8]^[6] Post-World War I adjustments continued to refine the service uniform for practicality. In 1926, an open-collared service coat was adopted to improve ventilation and wearer comfort, departing from the restrictive stand-up collars of earlier designs. By 1937, breeches were replaced with straight-leg trousers in olive drab wool or cotton, enhancing mobility; concurrently, the blue dress uniform was reintroduced exclusively for officers to restore some ceremonial tradition without burdening enlisted production lines.^[8]^[10] The two world wars profoundly influenced these pre-1950s evolutions, driving simplifications for rapid mass production and functionality. World War I's trench conditions necessitated heavier footwear and abbreviated formal elements, while interwar reforms and preparations for World War II emphasized economical, interchangeable components to equip a growing force efficiently. These changes established core principles of adaptability that laid the groundwork for subsequent green service uniforms.^[8]

Mid-20th Century Reforms (1950s–2000s)

In the post-World War II era, the U.S. Army sought to standardize its service uniforms amid evolving military needs during the Cold War. Drawing brief inspiration from the World War II-era "pinks and greens" officer uniform, the Army introduced the Army Green Class A uniform in 1954 as the primary service dress for all male personnel, effectively replacing the traditional blue uniforms for most daily and ceremonial garrison use.^[11]^[12] This shade 44 green wool uniform, featuring a single-breasted coat, trousers, and service cap, was part of a long-range improvement program initiated after the war to enhance practicality and uniformity across ranks.^[11] The design emphasized a professional appearance suitable for administrative and non-combat roles, becoming the standard for over six decades.^[6] Throughout the 1980s and 1990s, the Army Green uniform underwent minor modifications focused on improving wearer comfort and maintenance without altering its core aesthetic. Key updates included the adoption of permanent press fabrics, such as wool-polyester blends with easy-care finishes, particularly for trousers and shirts, to reduce ironing needs and enhance durability in garrison environments.^[13] These changes, informed by troop surveys and advisory groups, allowed for a single year-round fabric while preserving the traditional Army Green shade 344.^[13] By this period, the green uniform had solidified as a symbol of the professional Army identity, worn extensively during operations from Vietnam through the Gulf War, with only subtle adjustments to components like collars and pockets for better fit.^[6] Entering the 2000s, the rise of the Battle Dress Uniform (BDU), introduced in the early 1980s as the standard utility and field attire, indirectly shaped service wear practices by distinguishing combat from garrison roles more clearly.^[14] While the BDU's woodland camouflage pattern dominated daily operational use, the Army Green uniform retained its status for formal garrison and ceremonial duties, underscoring its enduring role in non-combat professionalism.^[6] This separation persisted into the early 21st century, even as combat uniforms evolved toward the Army Combat Uniform in 2004.^[14] The Army Green's prominence began to wane in the mid-2010s, culminating in its official retirement on October 1, 2015, as the blue Army Service Uniform assumed the primary service dress role for formal occasions.^[6] This shift marked the end of an era for the green uniform's mid-20th-century reforms, paving the way for subsequent reversals that revisited its legacy.^[6]

Recent Changes (2006–Present)

In 2006, the U.S. Army announced the introduction of the Army Blue Service Uniform (ABSU) as the new standard service uniform, intended to replace the longstanding Army Green Uniform and streamline the overall uniform suite.^[15] This change aimed to modernize the service dress while honoring traditional elements, with initial fielding beginning in 2010 and mandatory possession required by June 1, 2014.^[16] By 2015, the Army Green Uniform was officially retired on October 1, ending its wear-out period, after which the ABSU served as the mandatory service dress uniform.^[17] This policy shift solidified the blue uniform's role in daily and formal service wear, reflecting a decade-long phase-out of the greens that had been in use since the mid-20th century. On Veterans Day 2018, the Army announced the Army Green Service Uniform (AGSU), reviving the iconic "pinks and greens" style from World War II for use as the everyday service uniform.^[18] In 2020, the AGSU was authorized for optional wear, with initial issuances to drill sergeants and basic training units, while the ABSU was redesignated for optional formal and ceremonial occasions only.^[19] A 2027 mandate requires all soldiers to possess an AGSU by October 1, completing the phase-out of the blue uniform as the primary service dress and establishing the greens as the standard.^[7] As of November 2025, AGSU fielding continues across units, with the ASU remaining the primary service uniform during the phased transition. This ongoing transition emphasizes a return to historical roots while adapting to contemporary needs.

Current Versions

Army Green Service Uniform

The Army Green Service Uniform (AGSU) serves as the primary daily service uniform for U.S. Army personnel, designed for wear in garrison environments, daily duties, ceremonies, and formal or informal social functions. Officially approved and announced by the Secretary of the Army on November 11, 2018, the AGSU draws inspiration from the World War II-era "pinks and greens" uniform worn by service members of that period, but features a modern, unisex design to promote inclusivity and practicality across all ranks and genders. The uniform became available for purchase at select Army and Air Force Exchange Service locations starting in summer 2020, with full distribution to installations targeted for completion by mid-2021. As of 2025, the Army is in Phase II of the transition, focusing on limited user evaluation and broader adoption.^[7]^[20]^[7]^[21] The AGSU consists of a dark olive drab (heritage green 564) four-pocket, single-breasted coat with a detachable belt and notched lapels, paired with matching heritage taupe (565) trousers for men or slacks/skirt for women, a heritage tan (566) short- or long-sleeve shirt, an olive (heritage green) four-in-hand necktie, and brown leather oxfords (walnut brown 567). Constructed primarily from a 55% polyester/45% wool blend for the coat and trousers, and 75% polyester/25% wool for the shirt, the uniform emphasizes durability and ease of maintenance, with most components being machine-washable to support everyday use. It is offered in Class A configuration (full coat with tie for formal garrison settings) and Class B (shirt only, with optional no-tie for less formal occasions), along with a maternity variant (AGSU-M) featuring a tunic and 100% polyester fabrics for pregnant service members.^[7] Implementation of the AGSU follows a phased approach to ensure accessibility and transition from the previous Army Blue Service Uniform. Optional wear began immediately upon availability in 2020 for personnel who acquire it, with mandatory possession required for all soldiers by October 1, 2027, after which the blue uniform reverts to a ceremonial and formal dress role only. Enlisted personnel receive the AGSU through standard clothing bag issuance per Army regulations, with no additional cost to taxpayers as production occurs domestically. This timeline allows for gradual adoption while maintaining operational readiness.^[7]^[22]

Army Blue Service Uniform

The Army Blue Service Uniform (ABSU), also known as the Army Service Uniform in its blue variant, serves as the formal dress uniform for U.S. Army personnel, emphasizing ceremonial and official occasions since its transition to optional wear in 2020.^[7] Introduced in 2008 as the primary service uniform to replace the green Class A, it draws from traditional Army dress blues while incorporating modern fabrics for durability and ease of maintenance, such as a 55% polyester/45% wool blend.^[2] Following the adoption of the Army Green Service Uniform as the daily wear standard in 2020, the ABSU was phased from routine garrison use and reserved for formal events like promotions, military balls, weddings, and funerals, aligning with its role in upholding ceremonial traditions.^[7] The core of the ABSU is a midnight blue (shade 450) single-breasted coat featuring peaked lapels and four buttons, designed to extend below the waistline for a tailored fit.^[5] It pairs with lighter blue (shade 451) trousers for men or slacks for women, both cut with a low waistline for comfort; officers and noncommissioned officers (corporal and above) wear a 1.5-inch gold braid along the outer seams to denote leadership, while junior enlisted (private through specialist) have plain legs.^[1] The ensemble includes a white dress shirt with permanent creases, a black four-in-hand necktie for daytime wear (or black bow tie after retreat), and black low-quarter oxford shoes; combat boots are prohibited in ceremonial configurations to maintain a polished appearance.^[5] Headgear consists of the Army blue service cap as the standard for formal settings, with the insignia centered, or the black beret when authorized by the commander.^[5] Variants distinguish between officers and enlisted personnel through subtle accents that reflect rank and tradition. Officers' coats feature gold buttons and sleeve braid, enhancing the uniform's authoritative presence, whereas enlisted versions also use gold buttons for consistency, though without the sleeve braid.^[5] These differences ensure the ABSU remains versatile for both individual and unit ceremonies, with the dress configuration—lacking headgear and incorporating a bow tie—suited for evening social functions. Overall, the uniform's design prioritizes formality and heritage, making it a staple for events requiring heightened decorum without the utility focus of operational attire.^[16]

Components and Accessories

Upper Body Items

The upper body items of the Army Service Uniform (ASU) consist of coats, shirts, ties or neck tabs, and optional sweaters, with variations between the Army Green Service Uniform (AGSU) and Army Blue Service Uniform (ABSU) primarily in color and minor design elements.^[5] These components are constructed from durable wool-blend fabrics to ensure a professional appearance while allowing for ease of movement during formal and ceremonial occasions.^[5] The coat for the ABSU is a single-breasted, four-button design made from 55/45 percent polyester/wool serge in Army blue shade 450, featuring peaked lapels for males and notched lapels for females, with a hip-length cut that provides a tailored fit over the chest and shoulders.^[5] Male ABSU coats extend slightly below the crotch for a draped effect, while female versions include side-body construction for a smooth fit over the bust, with sleeves ending one inch below the wristbone and the bottom button positioned one inch below the waistline.^[5] In contrast, the AGSU coat uses 55/45 percent polyester/wool mock elastique in heritage green shade 564, also single-breasted with four buttons and peaked lapels, but includes a detachable waist belt and bi-swing back for enhanced mobility and a fitted silhouette over the chest and shoulders.^[5] Both coats are designed with four patch pockets to accommodate insignia placement, ensuring a structured yet comfortable upper body profile.^[5] Shirts for the ABSU are long-sleeved in Army white shade 521, made from 65/35 percent polyester/cotton with permanent creases and two chest pockets featuring flaps, offering a snug collar fit and ease over the back and chest while sleeves reach the wristbone.^[5] Female ABSU shirts include tuck-in or overblouse options with princess seams for a comfortable bust and waist fit.^[5] For the AGSU, shirts are heritage tan shade 566 in 75/25 percent polyester/wool, available in long- or short-sleeved versions with two chest pockets for males and semi-fitted designs for females, maintaining a snug collar and easy movement over the torso.^[5] A short-sleeved Class B shirt option exists for both variants, worn without a coat for less formal service settings.^[5] Ties and neck tabs complete the neckline, with the ABSU requiring a black four-in-hand tie for males or a black neck tab for females, both in polyester and tied neatly to sit no shorter than two inches above the belt buckle.^[5] The AGSU uses an olive (heritage green) four-in-hand tie for males or matching neck tab for females, also polyester, mandatory with long-sleeved shirts under the coat.^[5] Optional sweaters provide layering for both uniforms, including a black V-neck pullover in 100 percent wool or acrylic with shoulder and elbow patches for the ABSU, worn over the shirt with optional tie.^[5] For the AGSU, an optional olive (heritage green 564) V-neck pullover sweater in 100 percent non-pilling acrylic features epaulettes, shoulder patches, and elbow reinforcements, designed for comfortable layering over the tan shirt.^[5]^[23] A unisex black cardigan sweater in 50/50 acrylic/wool with five buttons is also authorized across variants for indoor or outdoor wear, buttoned fully when outdoors.^[5]

Lower Body and Footwear

The lower body components of the Army Service Uniform (ASU) include trousers or slacks for all personnel and optional skirts for women, designed to complement the upper body coat in fabric and color for a unified appearance. For the Army Green Service Uniform (AGSU), trousers and slacks are constructed from a wool blend fabric in heritage taupe shade 565, featuring a straight-leg cut with front and back creases for a formal silhouette, no cuffs, and a tailored fit that allows natural movement without bunching at the waist or hips.^[5] These items weigh approximately 6.8 ounces per square yard and are available in standard sizes to ensure uniformity across ranks.^[5] In the Army Blue Service Uniform (ABSU), trousers and slacks match the upper body in a 55/45 polyester/wool serge fabric weighing 9.5–10.5 ounces per square yard, in light blue shade 451 (or 151 for certain variants), with a straight-leg design, creases, and no cuffs for men, while women's slacks include a slight flare at the hem for comfort and fit over the hips.^[5] General officers wear dark blue shade 450 (or 150) versions with ornamental braiding along the outer seams, such as two 1/2-inch gold stripes, to denote rank distinction.^[5] Both genders' trousers and slacks must be pressed and free of wrinkles to maintain the uniform's professional standards.^[24] Women in the ASU have the option of wearing a skirt with either the AGSU or ABSU, consisting of a straight-cut, knee-length design in matching fabric and color—heritage taupe 565 for AGSU or light blue 451 for ABSU—with front and back creases and a hemline no shorter than 1 inch above or 2 inches below the knee crease for modesty and proportionality.^[5] The skirt features a side zipper and is fully lined for durability, ensuring it aligns seamlessly with the service coat without requiring additional adjustments.^[5] Belts are required for trousers and slacks across both AGSU and ABSU variants to secure the waistband and contribute to the overall polished look. In the AGSU, a heritage walnut shade 567 web belt, 1.25 inches wide for men and 1 inch for women, is worn with an open-faced buckle and brass tip, threaded through belt loops with the tipped end directed left for men and right for women.^[5] For the ABSU, a black web belt of the same widths uses a brass or black open-faced buckle, maintaining consistency in material (cotton web or synthetic) and ensuring the excess length does not extend more than two inches beyond the buckle.^[5] No visible suspenders are authorized, though invisible ones may be worn under trousers for support.^[24] Footwear for the ASU emphasizes low-profile, polished options to pair with the formal nature of the uniform, prohibiting athletic or casual shoes. AGSU personnel wear walnut brown shade 567 leather oxford shoes, low-quarter style with at least three eyelets, a plain toe, and a heel no higher than 2 inches, required in possession by October 1, 2027, for full compliance.^[5] Women may opt for matching pumps with a 0.5–3-inch heel and closed toe/heel design. In the ABSU, black leather low-quarter oxfords with similar specifications are standard for all, while women can choose black pumps for skirt ensembles, all in polished leather or poromeric material to ensure shine and durability.^[5] Socks or hosiery in coordinating colors—black or heritage green calf-length for dress wear—complete the footwear assembly.^[5]

Headgear and Outerwear

The headgear for the Army Service Uniform (ASU) consists of options tailored to the Army Green Service Uniform (AGSU) and Army Blue Service Uniform (ABSU), designed for formal and semi-formal wear while ensuring a professional appearance. For the AGSU, the primary headgear is the garrison cap, a unisex, foldable cap made of 55 percent polyester and 45 percent wool mock elastique in heritage green shade 564, worn straight and parallel to the ground with the front vertical crease aligned to the nose.^[5] Officers wear nonsubdued grade insignia centered on the left curtain, one inch from the front crease, while enlisted Soldiers position the distinct unit insignia (DUI) similarly on the left curtain.^[5] An optional service cap, also in heritage green 564 with a heritage walnut 567 leather visor, is authorized for corporals and above; it features the U.S. coat of arms insignia through the front eyelet for officers or a gold-colored disk with the coat of arms for enlisted personnel, centered on the front.^[5] The beret, made of wool in colors such as black, tan, green, maroon, or brown depending on the unit, serves as optional headgear for specific roles and is worn with the unit flash centered on the stiffener and grade insignia or DUI overlaid.^[5] For the ABSU, the garrison cap aligns with general service uniform standards, though specific material details emphasize conformity to Army specifications in Army blue shade 450.^[24] The service cap, in Army blue 450 with options for fur felt in officers' versions, includes male and female variants; officers wear a 2-3/8-inch gold-colored U.S. coat of arms on the front, while enlisted use a 1-1/2-inch disk version, with infantry personnel adding a blue plastic disk beneath.^[5] Female service hats feature a 1-5/8-inch coat of arms centered on the hatband for officers or a ringed version for enlisted.^[5] The beret follows the same construction and insignia rules as for the AGSU, optional for designated roles.^[5] Headgear is required outdoors with the ASU unless in formation or indoors, except when under arms or as directed, and must fit snugly without obstructing vision or bulging.^[24] Outerwear for the ASU provides weather protection and formality, with variations by uniform type using durable, weather-resistant materials like wool blends or coated fabrics. In the AGSU, the all-weather trench coat is a single-breasted option in heritage green 564, made of 65 percent polyester and 35 percent polyurethane-coated nylon, featuring an optional zip-out liner and optional oxidized silver grade insignia on the collar for officers or nonsubdued pin-on insignia for enlisted, positioned one inch from the collar point.^[5] The windbreaker, also in heritage green 564 from 55 percent polyester and 45 percent wool gabardine, includes a hook-and-loop liner and similar insignia placement, zipped to the second button when worn.^[5] The overcoat, in matching heritage green, offers additional protection with comparable insignia rules, while the Eisenhower jacket—a short, single-breasted semi-formal layer in heritage green 564—features grade insignia on shoulder loops for officers or sleeves for enlisted, fastened to the second button and authorized only with Class A or B configurations, not under pullovers.^[5] For the ABSU, outerwear emphasizes blue and black tones for cohesion. The all-weather trench coat is black, double-breasted with a belt and 65 percent polyester/35 percent cotton construction, allowing optional grade insignia on the collar as in the AGSU version.^[5] The windbreaker mirrors this in black gabardine with a liner, following identical insignia and zip rules.^[5] The ceremonial blue overcoat, a double-breasted polyester/wool garment for general officers, includes shoulder boards for rank and is reserved for formal cold-weather occasions, optionally paired with a white scarf.^[5] These items are optional, worn buttoned outdoors over the uniform (except for pregnant Soldiers who may unbutton), and not in formations unless authorized, prioritizing wool or poplin-like fabrics for resistance to elements while maintaining a tailored fit.^[24]

Insignia and Regulations

Rank, Branch, and Identification Insignia

The Army Service Uniform (ASU) displays rank insignia to denote the wearer's grade, with placements differing between enlisted personnel and officers, as well as between the Army Green Service Uniform (AGSU) and Army Blue Service Uniform (ABSU) variants. For enlisted Soldiers, nonsubdued cloth chevrons are sewn on both sleeves of the coat, centered between the shoulder seam and elbow; males wear 3-inch wide insignia, while females wear 2.5-inch versions, all on a heritage green 564 background for the AGSU and dark blue for the ABSU. Officers wear grade insignia—such as gold- or silver-colored bars, leaves, or stars—pinned or sewn centered on the shoulder loops of the coat, positioned 5/8 inch from the outer shoulder seam, with the base of the insignia oriented toward the collar. These configurations ensure visibility and adherence to formal standards, distinguishing the ASU from operational combat uniforms where rank may be subdued or infrared for tactical use. Branch insignia identifies the Soldier's professional specialty and is worn as polished metal pins on the coat lapels in Class A configurations. The U.S. insignia, consisting of gold-colored block letters "U.S.", is centered on the right lapel 5/8 inch above the notch, parallel to the ground;^[25] the branch-specific insignia (e.g., crossed rifles for infantry or a lightning bolt for signal corps) is similarly placed on the left lapel, 1 inch below the notch and parallel to the lapel edge. For Class B shirts without the coat, subdued fabric or metal versions of these insignia are authorized on the collar, with the U.S. pin 1 inch above the right pocket flap and branch pin 1 inch above the left. This lapel placement emphasizes organizational affiliation without the subdued or Velcro-attached elements common to combat attire. Identification elements on the ASU include nameplates and tapes for personal recognition, positioned above the right breast pocket and centered 1/8 inch above the top seam or pocket flap. Black nameplates with white lettering (1-5/16 by 3-13/16 inches) are standard for the ABSU, while the AGSU authorizes laminated plastic nameplates (dark brown with taupe lettering, 1 by 3 inches).^[26] Unlike operational uniforms, the ASU does not include U.S. Army tapes on the shoulders, focusing instead on polished, permanent attachments for ceremonial and service occasions. Combat and service awards are displayed as ribbons centered 1/8 inch above the left breast pocket, with up to four rows possible; badges like combat infantryman or expert marksmanship are worn 1/8 inch above the ribbons or 1/4 inch above the pocket if no ribbons are present. Decorations on the ASU vary by formality, with full-size medals suspended from ribbon bars worn centered on the left chest below the ribbons for dress variations, limited to five in a single row or arranged vertically if more are authorized. Miniature medals and decorations are used exclusively on mess and evening mess uniforms, pinned in the same position but scaled down (1/2 inch wide) for a compact appearance. Combat patches, or shoulder sleeve insignia-former wartime service (SSI-FWTS), are not permitted on the ASU, reserving such subdued, Velcro-backed items for utility and combat uniforms to maintain the ASU's formal, non-tactical profile.

Wear Standards and Occasions

The Army Green Service Uniform (AGSU) is authorized for year-round wear in garrison environments, including daily duty, promotions, and funerals, as well as informal social and official functions off duty.^[5] The Army Blue Service Uniform (ABSU), in contrast, is designated for more formal occasions such as military balls, weddings, and official visits by dignitaries, often in ceremonial or evening settings after retreat.^[5] Both variants of the Army Service Uniform (ASU) are prohibited in combat zones or field environments unless specifically authorized by a commander, to preserve their service and dress classification.^[24] Grooming standards emphasize a neat and professional appearance while in the ASU. Males must maintain a clean-shaven face, with mustaches authorized if neatly trimmed and not extending beyond the upper lip; beards are not authorized, even for medical or religious accommodations (effective September 30, 2025, with a one-year grace period for existing medical exemptions).^[27] Female soldiers' hair must be secured in a bun or other conservative style not exceeding the collar length, with a maximum bulk of 3 inches from the scalp and no ponytails or braids in dress configurations; hair must remain its natural color without dyes or unnatural styles.^[26] Fingernails should be trimmed and clean, with females allowed clear or neutral polish not exceeding 1/4 inch in length; cosmetics for females must be conservative and match natural skin tones, while males are prohibited from wearing any.^[26] Jewelry is restricted to wedding rings or a single conservative religious medallion on a chain not visible under the uniform; female soldiers may wear one pair of stud earrings (≤6 mm diameter) in gold, silver, or pearl, but no hoops, dangles, or additional pieces.^[26] Maintenance of the ASU requires uniforms to be clean, serviceable, and properly fitted, with shirts and trousers featuring pressed creases where applicable and oxford shoes polished to a high shine.^[5] Soldiers must wash AGSU items in cold water with mild detergent and tumble dry on low heat without starching or dry cleaning to maintain fabric integrity; ABSU components follow similar care, avoiding bleaching or excessive ironing.^[5] Inspection standards, as outlined in AR 670-1, mandate annual checks for uniform serviceability, with replacements issued via clothing allowances for enlisted personnel to ensure compliance during formations or evaluations.^[24] Prohibitions include mixing ASU components with civilian clothing or unauthorized items, such as combat boots or organizational brassards, to uphold uniformity.^[5] Alterations are limited to tailoring for proper fit, such as hem adjustments, and must conform to military specifications without modifying design elements like pocket placement or insignia areas; unauthorized changes, including commercial additions, are not permitted.^[24] Insignia must be worn in accordance with established guidelines to avoid discrepancies during wear.^[5]
