Ultimate Guide To The Army Service Uniform (ASU): Wear Regulations, Setup, And AGSU Comparison
The Army Service Uniform (ASU) stands as one of the most vital symbols of honor, discipline, and historical lineage within the United States Army. For years, the "Dress Blues" have served as the primary uniform for formal events, ceremonies, and professional appearances. Whether you are a newly enlisted soldier preparing for your first military ball or a seasoned non-commissioned officer (NCO) updating your service stripes, understanding the exact configurations of this uniform is essential for maintaining professional military appearance standards.
Governed strictly by Army Regulation 670-1 (AR 670-1) and Department of the Army Pamphlet 670-1 (DA PAM 670-1), the ASU requires meticulous attention to detail. Every ribbon, badge, and insignia must be placed with mathematical precision. Failure to comply with these guidelines not only detracts from a soldier's professional presentation but can also result in administrative corrective action. This comprehensive guide details everything you need to know about setting up, wearing, and maintaining your blue Army Service Uniform.
Blue ASU vs. AGSU: Understanding the Key Differences
In recent years, the Army transitioned its daily service uniform to the Army Green Service Uniform (AGSU), modeled after the classic "Pink and Greens" worn during World War II. This change shifted the primary role of the blue ASU. While the AGSU is now the standard uniform for daily business, recruiting, and office environments, the blue ASU remains the premier choice for formal, ceremonial, and social events.
The blue ASU can be configured as either a Class A (with coat) or Class B (shirt only) uniform, though its most common ceremonial application is as the Dress Blue configuration (with a bow tie for after-hours events). Understanding when to wear each uniform is critical for modern soldiers. The table below outlines the primary distinctions between the classic Blue ASU and the modern AGSU.
| Feature | Blue Army Service Uniform (ASU) | Army Green Service Uniform (AGSU) |
|---|---|---|
| Primary Color | Dark Blue Coat, Light Blue Trousers/Skirt | Olive Drab (Green) Coat, Taupe Trousers/Skirt |
| Primary Usage | Formal events, ceremonies, funerals, balls | Daily office wear, recruiting, business travel |
| Insignia Style | Polished brass, bright colored ribbons | Subdued/antique finish brass, subdued ribbons |
| Class B Variant | Short/long sleeve white shirt | Short/long sleeve khaki/tan shirt |
| Headgear | Service Cap (Blue) or Beret | Garrison Cap (Green) or Service Hat (Brown) |
| Footwear | Black oxford shoes or patent leather | Brown leather oxford shoes |
How to Correctly Set Up Your Army Service Uniform
Assembling the ASU is a precise process that requires a ruler, patience, and a solid understanding of military dress regulations. The placement of ribbons, qualification badges, unit awards, and the nameplate varies significantly depending on the gender of the soldier and the specific cut of the uniform jacket.
Proper placement ensures uniformity across the ranks, reflecting a high level of personal pride and attention to detail. Below are the precise specifications required to configure both the male and female blue ASU jackets according to DA PAM 670-1.
Male ASU Setup Specifications
For the male ASU jacket, all measurements are aligned using the pocket flaps as baseline reference points. The nameplate must be centered horizontally on the flap of the right breast pocket, positioned between the top of the button and the top of the pocket flap. The pocket flap acts as the anchor for almost all right-side insignia.
[ Unit Awards ] -> 1/8 inch above pocket [ Pocket Flap ] [ Nameplate ] -> Centered between top of pocket and button
- Ribbons: Ribbons must be centered on the left breast pocket flap, with the bottom row resting precisely 1/8 inch above the top of the pocket. They must be worn in order of precedence from the wearer's right to left.
- Unit Awards: Permanent and temporary unit award emblems (such as the Presidential Unit Citation) are centered horizontally 1/8 inch above the top of the right breast pocket.
- Badges: Marksmanship and combat/special skill badges are placed on the pocket flap. Marksmanship badges are centered on the pocket flap, 1/8 inch below the top seam. If multiple badges are worn, they must be spaced 1/4 inch apart.
Female ASU Setup Specifications
Because female ASU coats do not feature standard breast pockets, the placement of awards and nameplates is determined using a system of measurements based on the individual's anatomy and the layout of the lapel. The basic starting guideline is the imaginary horizontal line created by the top button of the jacket.
- Nameplate: The nameplate is placed horizontally on the right side of the uniform. It should be centered between the lapel seam and the arm seam, with the bottom of the nameplate aligned 1 to 2 inches above the top button of the jacket.
- Ribbons: Ribbons are centered on the left side of the jacket, with the bottom row aligned horizontally with the bottom of the nameplate. Adjustments may be made to accommodate different body types, but the parallel alignment with the nameplate must remain consistent.
- Unit Awards: Unit awards are centered on the right side of the jacket, exactly 1/2 inch above the top of the nameplate.

Maintenance, Fitting, and Professional Care
Maintaining the pristine condition of your blue ASU is a direct reflection of your military professionalism. Because the uniform contains delicate wool blends and polished metallic components, standard laundry practices will ruin the fabric. Professional dry cleaning is the only recommended method for cleaning both the ASU coat and trousers.
When sending your uniform to the dry cleaners, always remove all pin-on insignia, ribbons, unit awards, and brass. Failing to do so can result in permanent rust stains, tears in the fabric, or broken pins. It is highly recommended to store your uniform in a breathable garment bag, rather than a plastic cover, to prevent moisture buildup and fabric discoloration over time.
Alterations are another critical component of a sharp-looking ASU. Trousers must be tailored to fit cleanly over the polished black dress shoes, creating a slight break at the front of the laces while remaining slightly longer in the back. Sleeve lengths on the coat should fall to the prominent wrist bone, allowing approximately 1/4 to 1/2 inch of the white long-sleeve shirt cuff to show when standing at attention.
Frequently Asked Questions
Can I wear the blue ASU as a civilian after separating from the Army?
Generally, retired personnel and honorably discharged veterans are permitted to wear the ASU for specific formal occasions, such as military weddings, funerals, Memorial Day services, and retirement ceremonies. However, they must adhere strictly to the wear standards and grooming regulations of AR 670-1 while in uniform.
What is the difference between Class A and Class B configurations?
The Class A configuration requires the wear of the blue ASU coat, long-sleeve white shirt, tie or neck tab, and all authorized ribbons, badges, and accoutrements. The Class B configuration omits the coat, utilizing either the short-sleeve or long-sleeve white shirt with the tie/neck tab, nameplate, and a limited selection of ribbons and badges.
How do I polish the brass on my ASU?
Modern Army uniform brass, including collar insignia and belt buckles, is finished with a protective anodized coating designed to prevent tarnishing. You should not use abrasive brass polishes like Brasso on these items, as it will strip the coating. Instead, clean them gently with a soft microfiber cloth and warm soapy water if necessary.
Is the beret authorized for wear with the blue ASU?
Yes, the black beret (or organizational berets like maroon, tan, or green) is authorized for wear with both the Class A and Class B configurations of the blue ASU. However, for formal social events or when ordered by the commander, the Service Cap is the preferred headgear.
