US Army soldiers wearing green and tan uniforms
Army Green Service Uniform (AGSU)

The Army Service Uniform (ASU) is a military uniform for wear by United States Army personnel in garrison posts and at most public functions where the Army Combat Uniform is inappropriate. As of 2021, the Army has two service uniforms for use by its personnel. The Army Green Service Uniform, announced in 2018 and authorized in 2020, is used primarily for daily use in situations where civilians wear business attire, such as office settings or official meetings.

The Army Blue Service Uniform, which was the sole service uniform between 2015 and 2020, is used primarily as a dress uniform for ceremonial occasions or formal social situations. Over history, a number of different non-combat service uniforms have been authorized by the Army.

History

[edit]

In the early days of the U.S. Army, the uniform worn in combat was essentially the same as that worn for everyday duties, as was the common practice with most armies of the time. This changed in modern times, as field uniforms were developed which were more suited for battle.

During the 19th century, Army uniforms were relatively simple. Combat soldiers in the American Civil War wore a standard dark blue coat and light blue trousers, just like personnel in garrisons or in army offices and headquarters. Uniform standards were relaxed during the war years, especially on campaign, as conditions demanded.[1]

American Expeditionary Force soldier in uniform

The 1899 Army Uniform Regulations provided for a cotton khaki uniform for field service, drawing on the experience of the Spanish–American War when both blue and khaki clothing had been worn.[2] From 1902 to 1917, the army had three uniforms: a service uniform of olive drab wool cloth for use by soldiers in the field, a khaki cotton version used for hot weather, and a blue dress uniform used for ceremonies and off-post wear by enlisted men. The blue uniforms were dropped in 1917 prompted by the exigencies of World War I.[3]

In 1926, the previous stand collar service coat was replaced with an open-collared coat worn with a collared shirt and necktie. In 1937, breeches were replaced with straight-legged trousers. Dress uniforms of dark blue coats and light blue trousers in a modernized form with an open collar, white shirt, and necktie, were reintroduced for officers in 1937.[4]

United States Army uniforms in World War II initially included service uniforms that were intended for both field and garrison use, though some parts, such as the open-collared service coat, were used only in garrison, while items such as the M1941 field jacket were specifically for use in the field, and not meant to be worn in garrison.[5] By the latter part of the war, the introduction of the M1943 field uniform acknowledged the distinction between field and garrison wear.

Garrison uniforms included olive drab uniforms with coat and tie which were distinct for officers and enlisted soldiers. The officers' version had a darker, belted coat that could be worn with trousers of either matching color or a contrasting light taupe, a combination known as "pinks and greens". The enlisted service coat was unbelted and lighter in shade, and was worn with the issued field uniform trousers. Service coats would be worn with either the respective wool shirt in matching olive drab or the tan shirt from the summer uniform.[4][6]

A summer service uniform consisting of a khaki cotton shirt and trousers was also issued to enlisted soldiers. Officers' khaki service uniforms could be made from tropical-weight worsted wool instead of cotton and had an optional unbelted khaki service coat, though these were less common as conserving wool for winter uniforms was encouraged. Unlike the winter uniforms, parts of which continued to be widely used as field uniforms, the khaki summer uniforms were quickly relegated only for garrison wear as the herringbone twill utility uniform became the preferred warm weather field uniform. Late in the war the Eisenhower jacket was introduced, originally intended for both field and garrison wear, though it too became used only for garrison wear shortly after the war. These uniforms remained in use through the Korean War.[4][6]

The green "Class A" service uniform, worn by former Army Chief of Staff General Peter Schoomaker.

Because of the widespread use of army surplus clothing after World War II, a fresh, distinct uniform was seen as needed.[7][8] In 1954, the Army introduced a new, all-ranks "Class A" service uniform in Army Green shade 44. This grey-green shade was adopted in order to provide a color which had a distinct military appearance from various uniforms of civilian service workers.[3] Originally worn with a tan shirt, the shirt was switched to a pale green-grey shade in 1979.[4]

The tan summer service uniform was retained with a matching coat reintroduced, but following the introduction of a tropical weight version of the "Class A" greens in 1964, the tan uniform was relegated to a "Class B" uniform with a short-sleeved shirt and no tie. The tan "Class B" uniform was phased out the 1980s when the green uniform with a short sleeve shirt became the standard Class B uniform.[4]

In the mid 1950s, the blue dress uniform was reintroduced as an option for enlisted soldiers.[4] A white dress uniform for use in tropical areas, last worn in the early 20th century, was reintroduced, but was rarely used, as it was only required for officers.[4] It was retired in 2014.[8]

In 2006, Army Chief of Staff General Peter Schoomaker announced that a version of the dress blue uniform would be adopted as the sole service uniform for all ranks, combining ceremonial, dress, and service uniforms through wear stipulations to reduce the number of uniforms needed. The blue Army Service Uniform made its debut at the 2007 State of the Union Address, when Schoomaker attended the address in it.[8] In 2010 it started being issued to all soldiers.[8][9] Possession and use of the blue ASU became mandatory for all soldiers in October 2015,[9] when the green Class A uniform was fully retired.[8][10]

On Veterans Day 2018, the Army announced that a new Army Green Service Uniform, based on the "pinks and greens" officers' service uniform worn in World War II and the Korean War, would be introduced as the everyday service uniform for all ranks starting in 2020.[11] The uniform became available to soldiers in mid-2020.[12] By early 2021, the uniform became available for purchase at all Army and Air Force Exchange Service locations,[13] with soldiers required to purchase them by October 1, 2027. The Army Blue Service Uniform returns to its former use as a formal dress uniform.[12][14]

The Army Green Service Uniform includes a dark olive drab four-pocket coat with belted waist, drab trousers, tan shirt, olive tie, and brown leather oxfords for both men and women. Women have the option to wear a pencil skirt and pumps instead. Headwear consists of an olive garrison cap or an olive peaked service cap with brown visor; units with distinctive colored berets continue to wear them. An olive trench coat is the standard all-weather overcoat with the uniform. Enlisted rank is indicated by chevrons worn on the upper sleeve. Officer rank is indicated by pins on the shoulder straps.[14][15][11][16]

In class B configuration, the service coat is omitted, and the necktie is optional if a short-sleeved shirt is worn. An olive pullover sweater is authorized with the class B uniform, while optional jackets include an olive zip-front windbreaker, an olive Eisenhower jacket, and a brown leather bomber jacket.[17]

Army Blue Service Uniform

[edit]

The Army Blue Service Uniform includes a midnight blue coat worn with lighter blue trousers for male soldiers and a midnight blue coat worn with either lighter blue slacks or midnight blue skirt for female soldiers. The trousers/slacks for non-commissioned and commissioned officers include a stripe of gold braid on the outer side of the leg. Generals wear midnight blue trousers/slacks with gold braid instead of the lighter blue used in lower ranks.[10][18]

The blue service uniform is worn with a white shirt, a black four-in-hand necktie for males or black neck tab for females, and black leather shoes. Headwear includes a matching service cap with branch-of-service colors on the hat band or a beret, with black remaining the default color unless the soldier is authorized a distinctive colored beret. Enlisted rank is also indicated by chevrons on the upper sleeve, while officer rank is indicated by passant shoulder straps with branch-of-service color backing.[10][18]

Combat boots and organizational items, such as brassards, military police accessories, or distinctive unit insignia are not worn when used as ceremonial dress. When the blue uniform is worn for social events in the evening, men may wear a black bow tie rather than a black four-in-hand necktie, and commanders may direct that headwear is not required.[10][18]

The Army Service Uniform (ASU) is the standard service uniform of the , serving as a versatile dress option for semi-formal, formal, and ceremonial occasions while providing a professional appearance for office and business environments. It consists of a , belted or slacks, a long- or short-sleeve shirt, and accessories such as a black four-in-hand or turtleneck, all in shade 450 or 451, made from a durable 55% and 45% tropical-weight fabric. 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. Introduced on August 20, 2008, the ASU was developed to replace the Green Service Uniform, which had been in use since the mid-1950s, as part of broader transformation efforts initiated in 2004 to modernize and streamline uniform options. Derived from the longstanding Dress Blue Uniform, it features a wrinkle-resistant, athletic-cut for improved wearability and includes updated such as combat service identification badges and shoulder-loop . Initial fielding of new ASU items began in 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. 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 heritage while serving as the new everyday business attire. 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. 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.

Purpose and Overview

Role in the US Army

The Army Service Uniform (ASU) serves as the primary non-combat for U.S. Army personnel in environments and official capacities, worn during office duties, public events, and formal ceremonies where the (ACU) or (OCP) would be inappropriate. It functions as both a service for everyday business attire in non-field settings and a for ceremonial occasions, with the service variant emphasizing practicality for routine tasks and the variant incorporating formal elements like full medals for parades and official functions. 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. This uniform replaced the older Army Green Service Uniform (Class A greens), which was phased out by October 1, 2015. 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. 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. 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.

Design Principles

The Army Service Uniform (ASU) is designed with core principles emphasizing , formality, and through the use of or wool-blend fabrics, typically a 55 percent and 45 percent blend in serge, tropical, , or elastique weaves weighing 9 to 16 ounces. The Army Green Service Uniform (AGSU) uses a 55 percent and 45 percent weave, with the at 8.7 ounces and at 6.8 ounces. These materials provide a structured yet resilient suitable for professional wear while evoking the timeless formality of attire. Conservative cuts, featuring tailored jackets that fit easily over the chest and shoulders with slight curves at the hips, high-waisted with a modest break, and knee-length skirts, draw inspiration from historical uniforms to maintain a dignified that balances with practicality. Gender-neutral adaptations ensure inclusivity and functionality, offering options such as slacks or for personnel alongside maternity tunics, all prioritized for , 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 —to promote comfort during daily duties while upholding professional standards; sheer, skin-complementary and closed-toe pumps further support without patterns or excessive ornamentation. These elements reflect a commitment to equitable design across genders, allowing for body configuration variations without compromising the uniform's authoritative presence. Color schemes reinforce the uniforms' service and dress roles, with olive drab greens (heritage green 564) for the AGSU service variant, or dark blue (450/150) for ASU dress occasions, and tan shirts (heritage tan 566, 75 percent /25 percent ) paired with matching ties or neck tabs to create a cohesive, understated palette. Modern designs incorporate and 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. This evolution briefly nods to WWII-era "pinks and greens" influences in the AGSU's heritage styling, prioritizing enduring functionality over fleeting trends.

Historical Development

Origins and Early Evolution (Pre-1950s)

The origins of the Army Service Uniform trace back to the late , when the U.S. Army sought more practical attire for field service amid expanding overseas operations. In 1899, uniforms were officially adopted to replace the traditional dark blue garments, which had been standard since the Revolutionary War era but proved impractical for campaigns in tropical climates like the and 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. From 1902 to 1917, the Army standardized olive drab wool service coats for winter wear and 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 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. 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, were replaced with straight-leg in olive drab or , enhancing mobility; concurrently, the blue dress uniform was reintroduced exclusively for officers to restore some ceremonial tradition without burdening enlisted production lines. The two world wars profoundly influenced these pre-1950s evolutions, driving simplifications for rapid and functionality. World War I's trench conditions necessitated heavier footwear and abbreviated formal elements, while interwar reforms and preparations for 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.

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 . 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 use. This shade 44 green wool uniform, featuring a , , and service cap, was part of a long-range improvement program initiated after the war to enhance practicality and uniformity across ranks. The design emphasized a professional appearance suitable for administrative and non-combat roles, becoming the standard for over six decades. Throughout the and , 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 and , to reduce needs and enhance durability in environments. These changes, informed by troop surveys and advisory groups, allowed for a single year-round fabric while preserving the traditional Army Green shade 344. By this period, the green uniform had solidified as a symbol of the professional Army identity, worn extensively during operations from through the , with only subtle adjustments to components like collars and pockets for better fit. Entering the 2000s, the rise of the (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. 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. This separation persisted into the early 21st century, even as combat uniforms evolved toward the in 2004. 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. 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.

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. 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. By 2015, the Army Green Uniform was officially retired on , ending its wear-out period, after which the ABSU served as the mandatory . 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 2018, the Army announced the Army Green Service Uniform (AGSU), reviving the iconic "pinks and greens" style from for use as the everyday service uniform. 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. A 2027 mandate requires all soldiers to possess an AGSU by , completing the phase-out of the blue uniform as the primary service dress and establishing the greens as the standard. 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 Green Service Uniform (AGSU) serves as the primary daily service uniform for U.S. personnel, designed for wear in environments, daily duties, ceremonies, and formal or informal social functions. Officially approved and announced by the Secretary of the on , 2018, the AGSU draws inspiration from the 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 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 is in Phase II of the transition, focusing on limited user evaluation and broader adoption. 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. 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 regulations, with no additional cost to taxpayers as production occurs domestically. This timeline allows for gradual adoption while maintaining operational readiness.

Army Blue Service Uniform

The Blue Service Uniform (ABSU), also known as the Army Service Uniform in its blue variant, serves as the formal dress uniform for U.S. personnel, emphasizing ceremonial and official occasions since its transition to optional wear in 2020. 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% /45% blend. Following the adoption of the Army Green Service Uniform as the daily wear standard in 2020, the ABSU was phased from routine use and reserved for formal events like promotions, balls, weddings, and funerals, aligning with its role in upholding ceremonial traditions. The core of the ABSU is a (shade 450) single-breasted coat featuring peaked lapels and four buttons, designed to extend below the waistline for a tailored fit. It pairs with lighter (shade ) trousers for men or slacks for women, both cut with a low waistline for comfort; officers and noncommissioned officers ( and above) wear a 1.5-inch gold braid along the outer seams to denote , while junior enlisted (private through ) have plain legs. The ensemble includes a white with permanent creases, a black four-in-hand for daytime wear (or black after retreat), and black low-quarter oxford shoes; combat boots are prohibited in ceremonial configurations to maintain a polished appearance. Headgear consists of the service as the standard for formal settings, with the centered, or the when authorized by the commander. 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. These differences ensure the ABSU remains versatile for both individual and unit ceremonies, with the dress configuration—lacking and incorporating a —suited for evening social functions. Overall, the uniform's design prioritizes formality and heritage, making it a staple for events requiring heightened without the utility focus of operational attire.

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 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 5/8 inch above the notch, parallel to the ground; the branch-specific insignia (e.g., crossed for or a lightning bolt for ) is similarly placed on the left , 1 inch below the notch and parallel to the 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 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 nameplates (dark brown with lettering, 1 by 3 inches). Unlike operational uniforms, the ASU does not include U.S. tapes on the shoulders, focusing instead on polished, permanent attachments for ceremonial and service occasions. and service awards are displayed as ribbons centered 1/8 inch above the left pocket, with up to four rows possible; badges like 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 environments, including daily duty, promotions, and funerals, as well as informal social and official functions off duty. The Army Blue Service Uniform (ABSU), in contrast, is designated for more formal occasions such as balls, weddings, and official visits by dignitaries, often in ceremonial or evening settings after retreat. Both variants of the Army Service Uniform (ASU) are prohibited in combat zones or field environments unless specifically authorized by a , to preserve their service and dress classification. 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 or religious accommodations (effective September 30, , with a one-year for existing exemptions). Female soldiers' hair must be secured in a or other conservative style not exceeding the collar length, with a maximum bulk of 3 inches from the and no ponytails or braids in dress configurations; hair must remain its color without dyes or unnatural styles. Fingernails should be trimmed and clean, with females allowed clear or neutral polish not exceeding 1/4 inch in length; for females must be conservative and match skin tones, while males are prohibited from wearing any. Jewelry is restricted to 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 ) in gold, silver, or pearl, but no hoops, dangles, or additional pieces. 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. 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. 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. Prohibitions include mixing ASU components with civilian clothing or unauthorized items, such as combat boots or organizational brassards, to uphold uniformity. Alterations are limited to tailoring for proper fit, such as hem adjustments, and must conform to specifications without modifying design elements like pocket placement or areas; unauthorized changes, including commercial additions, are not permitted. must be worn in accordance with established guidelines to avoid discrepancies during wear.
