Army ASU Wear Guide 2026: Official DA PAM 670-1 Uniform Setup And Inspection Standards

Clarification Note: This guide outlines the official wear standards, measurement placement, and alignment rules for the U.S. Army Blue Service Uniform (ASU) and Army Dress Uniform (ADU) under current Department of the Army Pamphlet (DA PAM) 670-1 and Army Regulation (AR) 670-1 guidelines as updated for 2026. For daily business attire under the active multi-uniform system, personnel should reference specific Army Green Service Uniform (AGSU) directives.

Adhering to military uniform regulations is a foundational element of professionalism, discipline, and military bearing. The Blue Army Service Uniform (ASU) serves as the U.S. Army’s premier formal service and dress attire for ceremonial duties, official functions, boards, and formal social events. Establishing an inspection-ready uniform requires strict adherence to exact measurement protocols, component positioning, and regulatory distinction between officer and enlisted wear.

Department of the Army Regulatory Framework for ASU Wear

The authorization, composition, and presentation of the Blue Army Service Uniform are governed by Army Regulation 670-1 (AR 670-1) and detailed execution procedures in Department of the Army Pamphlet 670-1 (DA PAM 670-1).

Under 2026 standards, the Blue ASU is categorized into distinct configurations:

• Class A ASU: Includes the blue coat, long-sleeve or short-sleeve blue shirt, necktie or necktab, and slacks, trousers, or skirt.
• Class B ASU: Omits the blue coat. The long-sleeve blue shirt with necktie/necktab or the short-sleeve shirt (with optional tie/necktab) is worn as the outer garment with slacks, trousers, or skirt.
• Army Dress Uniform: Formed when the Class A ASU is worn with a black bow tie (for males) or black necktab/formal accessories for evening and formal ceremonial occasions.

Uniform Material and General Appearance Standards

All components must present a clean, pressed, and tailored fit. Creases on the blue coat are strictly prohibited. Trousers and slacks must feature clean, sharp vertical creases centered on the front and back of each leg, extending from the bottom of the belt loops down to the bottom hem. The bottom hem of the trousers must rest on the top of the shoe with a slight break, angled downward toward the rear boundary of the heel.

Male Army Service Uniform Component Specifications

Setting up the male Class A and Class B ASU requires precise vertical and horizontal measurements using a standard military seamstress gauge.

[ Male ASU Coat Measurement Key ] +-------------------------------------------------+ | Right Side Left Side | | - Unit Citations: 1/8" - Ribbons: 1/8" | | above pocket flap above pocket flap | | - RDI: 1/4" above - Badges: 1/4" below | | citations/pocket pocket flap seam | | - Nameplate: Centered - Regimental Crest | | on pocket flap (if authorized) | +-------------------------------------------------+

(Diagram provided for visual reference; follow precise written measurements below.)

1. Nameplate Placement

• Position: Centered horizontally on the flap of the right breast pocket.
• Vertical Alignment: Positioned vertically between the top of the pocket button and the top seam of the pocket flap.

2. Ribbon Rack Alignment

• Position: Centered horizontally on the left breast pocket flap.
• Vertical Alignment: The bottom edge of the ribbon frame sits 1/8 inch above the top seam of the left breast pocket flap.
• Overlap and Notch: When lapels obscure portions of a ribbon rack containing four or more rows, ribbons may be worn in a notched configuration or aligned flush to the left pocket seam.

3. Combat and Special Skill Badges

• Marksmanship Badges: Centered horizontally on the left pocket flap, 1/8 inch below the top seam of the pocket flap. If multiple badges are worn, space them at least 1 inch apart.
• Special Skill Badges (Group 1–5): Worn 1/4 inch above the ribbon rack. Additional badges are spaced 1/2 inch apart vertically above the lower badge.
• Badges on Pocket Flap: Badges authorized for wear on the pocket flap must be centered between the lower seam of the flap and the bottom of the buttonhole.

4. Unit Citations and Regimental Insignia

• Unit Citations (Right Side): Centered horizontally 1/8 inch above the top edge of the right breast pocket flap.
• Regimental Distinctive Insignia (RDI): Centered 1/4 inch above the top edge of the unit citation emblem. If no unit citations are worn, the RDI sits 1/4 inch above the top seam of the right pocket flap.

5. Enlisted Rank and Officer Insignia

• Enlisted Sleeve Rank: Sewn centered on the outer sleeve between the shoulder seam and the elbow bend on both arms.
• Commissioned and Warrant Officer Rank: Officers wear shoulder straps (epaulets) attached to the coat shoulders featuring embroidered grade insignia. Branch insignia is mounted on the coat lapel centered 1-1/4 inches above the notch, with the bottom of the insignia parallel to the inside edge of the lapel.

Female Army Service Uniform Component Specifications

Because the female ASU coat lacks breast pockets, placement relies on structural landmarks including the coat buttons and seam lines.

1. Nameplate Placement

• Position: Centered horizontally on the right side of the coat.
• Vertical Alignment: Positioned 1 to 2 inches above the top button, adjusted symmetrically to match the individual’s body structure. The bottom of the nameplate should align horizontally with the bottom row of the ribbon rack on the left side.

2. Ribbon Rack Alignment

• Position: Centered horizontally on the left side of the coat.
• Vertical Alignment: The bottom edge of the ribbon rack sits 1 to 2 inches above the top button, parallel to the floor, maintaining visual balance with the nameplate.

3. Unit Citations and Regimental Insignia

• Unit Citations (Right Side): Centered on the right side, 1/2 inch above the top edge of the nameplate.
• Regimental Distinctive Insignia (RDI): Centered 1/4 inch above the top edge of the unit citation emblem (or 1/4 inch above the nameplate if no unit citations are worn).

4. Identification and Skill Badges

• Special Skill Badges: Centered horizontally 1/4 inch above the top row of ribbons.
• Identification Badges (e.g., Recruiter, Drill Sergeant, Joint Chiefs): Centered on the designated right or left side lower pockets or parallel anatomical equivalent, positioned between the waistline and lower coat hem.

5. Female Slacks and Skirt Guidelines

• Slacks: Fitted at the natural waistline. The hem must fall between the ankle joint and top of the shoe, forming a clean line without excessive sagging.
• Skirt: Worn at the natural waistline. The skirt length must fall between 1 inch below the midpoint of the kneecap and 1 inch above the bottom of the kneecap.

Step-by-Step Guide to Assembling an Inspection-Ready ASU

Achieving an outstanding score on an inspection or board requires absolute precision. Follow this systematic workflow to construct an error-free uniform.

Step 1: Fabric Preparation and Thermal Pressing

Inspect the uniform for loose threads (frais), fabric pilling, or lint. Steam or dry-iron the trousers, slacks, or skirt to establish razor-sharp front and rear leg creases. Ensure the blue coat is steamed to remove storage wrinkles; never place sharp creases down the sleeves of the blue coat.

Step 2: Establish Baseline Measurement Anchor Points

Before mounting hardware, place the coat on a flat surface or uniform template board.

1. Measure the exact horizontal center of the pocket flaps (Male) or measure 1 to 2 inches above the top button (Female).
2. Mark the anchor points lightly using tailor’s chalk or transparent alignment guides.

Step 3: Mount Ribbon Racks and Unit Citations

Assemble ribbons onto a sturdy multi-ribbon bar. Ensure ribbons are clean, unfaded, mounted in proper order of precedence (federal awards preceding state or foreign awards), and tightly aligned without gaps.

• Align male ribbons 1/8 inch above the left pocket flap.
• Align female ribbons horizontally with the designated line 1 to 2 inches above the top button.
• Attach unit citations on the right side following identical parallel alignment rules.

Step 4: Affix Badges, RDI, and Insignia

Pin badges securely into place using plastic or brass backings.

Operational Tip for Stability: Place thin felt, cardboard, or foam backing behind the fabric interior prior to pushing clutch pins through the coat. This prevents heavy badges from drooping forward and preserves fabric tension during movement.

Step 5: Execute the Gig-Line Check (Class B and Shirt Wear)

When wearing the Class B uniform, ensure the front placket of the blue shirt, the edge of the belt buckle, and the trouser fly seam form one continuous vertical line down the body (the "gig-line"). The belt tip must extend through the buckle without revealing velcro or raw fabric edges, extending no more than 1 to 2 inches past the buckle edge for traditional brass fittings.

Common Uniform Violations and Corrective Actions

During command inspections, failure points usually stem from minor displacement of accoutrements or neglected maintenance.

Incorrect Gig-Line Alignment

• Defect: The shirt edge, belt buckle, and trouser fly fail to form a straight line.
• Remedy: Tuck the shirt tightly using a professional military tuck (folding excess fabric backward toward the spine) before securing the waist enclosure. Align the edge of the brass belt buckle precisely with the shirt placket.

Sagging Badges and Ribbon Tilt

• Defect: Heavy marksmanship or airborne badges cause the thin pocket or jacket fabric to sag, making badges appear crooked.
• Remedy: Insert reinforced backing material inside the pocket flap or coat lining to distribute badge weight evenly against the fabric.

Frayed Ribbon Edges and Tarnished Brass

• Defect: Thread fraying along ribbon borders or oxidized brass belt buckles and pins.
• Remedy: Use a fabric shaver or lighter flame (carefully applied) to clear minor thread fraying. Polish all brass components with an approved non-abrasive metal cleaner prior to final mounting.

Frequently Asked Questions About Army ASU Wear
