Ultimate AGSU Short Sleeve Set Up Guide: 2026 Army Regulations & Inspection Standards

The Army Green Service Uniform (AGSU) stands as the primary service uniform for the United States Army. Achieving a flawless "Class B" setup—the configuration featuring the Heritage Tan 381 short-sleeve shirt worn without the service coat—demands meticulous attention to detail, exact measurements, and strict compliance with Department of the Army Pamphlet 670-1 (DA PAM 670-1) and Army Regulation 670-1 (AR 670-1).

In professional military environments, your appearance is a direct reflection of your attention to detail, discipline, and respect for the heritage of the service. This technical guide delivers the precise, zero-error measurement specifications, placement rules, and expert tips required to assemble a perfect AGSU short-sleeve shirt setup for both male and female soldiers.

Anatomy of the Male AGSU Short-Sleeve Setup

The male Heritage Tan short-sleeve shirt features two breast pockets with button-down flaps. Because these pockets serve as physical anchor points, they make vertical and horizontal alignment more straightforward. However, they also leave no margin for error, as any deviation from the pocket lines is immediately visible to inspectors.

Nameplate and Unit Award Placement

The male nameplate must be centered horizontally on the right breast pocket flap. Vertically, it must be positioned between the top of the pocket flap and the top of the pocket button hole, leaving a clean, balanced margin above and below the nameplate.

Unit awards (such as the Presidential Unit Citation, Valorous Unit Award, or Joint Meritorious Unit Award) are worn on the right side of the shirt. Center the unit award ribbon bar horizontally over the right breast pocket, exactly 1/8 inch above the top pocket seam. If you wear multiple unit awards, stack them in order of precedence with no space between the ribbon frames.

Ribbon Rack and Special Skill Badges

Your personal ribbons are worn on the left side of the short-sleeve shirt. The ribbon rack must be centered horizontally above the left breast pocket, with the bottom row resting exactly 1/8 inch above the top pocket seam.

Combat and Special Skill badges (Groups 1 through 5, such as the Combat Infantryman Badge, Combat Action Badge, Airborne Wings, or Air Assault Badge) are positioned above the ribbon rack:

• Single Badge: Center the badge horizontally 1/4 inch above the top row of ribbons.
• Multiple Badges: When wearing two or more badges above the ribbons, stack them vertically with 1/2 inch of space between the badges. Ensure they are centered horizontally over the ribbon rack.
• No Ribbons Worn: If you opt not to wear ribbons on the Class B shirt, center the badges horizontally 1/4 inch above the top left pocket seam.

Marksmanship Badges and Identification Badges

Marksmanship badges and driver/mechanic badges are worn on the left pocket flap. Center the badge horizontally on the flap, with the upper edge of the badge mount exactly 1/8 inch below the top seam of the pocket flap.

If you wear multiple marksmanship or specialty badges, space them evenly across the pocket flap, keeping them 1/8 inch below the top seam. No more than three badges are authorized on the pocket flap.

Anatomy of the Female AGSU Short-Sleeve Setup

The female Heritage Tan short-sleeve shirt does not feature chest pockets. This pocketless design accommodates the female silhouette more comfortably but requires careful measurement, as you cannot rely on pocket seams for alignment. Instead, all measurements are taken relative to the shirt's buttons and the natural contours of the soldier's frame.

Aligning the Nameplate, Ribbons, and Unit Awards

Without pocket flaps to guide you, the alignment of the right and left sides must be established using a horizontal baseline.

• Nameplate: Center the nameplate on the right side of the chest. It must be positioned 1 to 2 inches above the top button, adjusted as necessary to sit flat and level against the bust line.
• Ribbons: Center the ribbon rack horizontally on the left side of the chest. The bottom row of the ribbon rack must align horizontally with the bottom edge of the nameplate on the opposite side.
• Unit Awards: Center unit awards on the right side of the chest, positioned exactly 1/2 inch above the top edge of the nameplate.

Combat, Special Skill, and Marksmanship Badges

Because there are no pockets, the placement of badges on the female shirt mimics the visual layout of the male shirt but utilizes calculated distances from the ribbons.

• Combat and Special Skill Badges: Center these badges horizontally 1/4 inch above the top row of ribbons. If wearing multiple badges above the ribbons, stack them vertically with 1/2 inch of space between each badge.
• Marksmanship Badges: Center marksmanship badges horizontally on the left side, exactly 1/4 inch below the bottom row of your ribbon rack. If you choose not to wear ribbons, place the marksmanship badges in the same relative position where the bottom of the ribbon rack would naturally fall.

Rank Insignia and Shoulder Loop Configurations

Rank placement on the AGSU short-sleeve shirt depends entirely on whether you are an Officer, a Non-Commissioned Officer (NCO), or a Junior Enlisted soldier.

Officers and NCOs (Corporal through Sergeant Major)

Officers and NCOs wear slip-on shoulder marks (frequently called shoulder boards) over the shirt's shoulder loops.

• Shoulder Marks: Slip-on rank insignia must slide completely onto the shoulder loops. The rank must face the correct direction, with the pointed end of the shoulder loop buttoning securely over the inner tab of the shoulder mark.
• Distinctive Unit Insignia (DUI): When slip-on shoulder marks are worn on the short-sleeve shirt, the DUI is not worn on the shoulder loops. There is simply not enough physical space on the loop, and pinning a DUI through a shoulder mark is unauthorized. Instead, enlisted soldiers wear their DUI on the Garrison Cap.

Junior Enlisted (Private through Specialist)

Junior enlisted personnel do not wear slip-on shoulder marks. Instead, they use pin-on rank insignia on the shirt collars.

• Collar Rank Placement: Center the rank insignia on both the left and right collars. Position the insignia exactly 1 inch from the collar point, with the centerline of the rank bisecting the collar point.
• DUI Placement on Shoulder Loops: Because junior enlisted soldiers do not wear shoulder marks, they must wear their DUI centered on both shoulder loops. Center the DUI fabric-to-metal pin-on base on the shoulder loop, positioned at an equal distance between the collar seam and the shoulder loop button.

Comprehensive AGSU Class B Setup Comparison

The following technical comparison table outlines the exact placement, clearances, and dimensions for both male and female configurations on the AGSU short-sleeve shirt.

Step-by-Step Guide to Assembling Your AGSU Class B Uniform

Assembling the short-sleeve shirt requires patience and a steady hand. Utilizing the proper tools—such as a clear plastic uniform ruler, a heavy-duty sewing needle or pinning tool, and backing cardboard—will prevent damage to the Heritage Tan fabric and guarantee perfect alignment.

Step 1: Prep and Press the Shirt

Before pinning anything, professionally press or iron the shirt. Ensure the collar crease is sharp and the shoulder loops lay completely flat. If your command allows starch, use it sparingly; the AGSU wool-blend fabric is designed to drape naturally and can look unnaturally stiff if over-starched.

Step 2: Install Rank Insignia

If you are a Corporal or above, slide your rank slip-ons onto the shoulder loops. Ensure they are pressed flat and pushed as far down the loop toward the shoulder seam as possible before buttoning the loop. If you are a Specialist or below, measure 1 inch from the collar point, mark the spot lightly with a fabric pencil or your thumb, and pin your collar rank so that the centerline of the insignia points directly at the collar corner.

Step 3: Align the Right Side (Nameplate & Unit Awards)

For male soldiers, place the nameplate flat on the right pocket flap, align it horizontally, and push the pins through. If wearing unit awards, place your uniform ruler against the top seam of the pocket and mark a line exactly 1/8 inch above it. Pin the unit award rack along this line.

For female soldiers, measure 1 to 2 inches above the top button on the right breast. Pin the nameplate horizontally at this level. Next, measure exactly 1/2 inch above the top of the nameplate and pin your unit awards, ensuring they are perfectly centered over the nameplate.

Step 4: Align the Left Side (Ribbons & Badges)

For male soldiers, align the bottom of the ribbon rack exactly 1/8 inch above the left pocket seam. Pin it securely. If wearing combat or skill badges, measure 1/4 inch above the top row of ribbons and pin. For marksmanship badges, measure 1/8 inch down from the top seam of the left pocket flap and pin the badge centered on the flap.

For female soldiers, place a ruler horizontally across the chest from the bottom edge of the pinned nameplate to the left side. Mark this baseline. Place the bottom of your ribbon rack on this line and pin. If wearing combat badges, measure 1/4 inch above the ribbons. If wearing marksmanship badges, measure 1/4 inch directly below the bottom row of your ribbons and pin.

Step 5: Reinforce and Inspect

Because the AGSU short-sleeve shirt fabric is lightweight, heavy ribbon racks or multiple badges can pull down on the material, causing the shirt to sag and the medals to slant downward.

Expert Tailoring Pro-Tip Cut a small piece of thin plastic (such as an old credit card or a plastic milk jug) or stiff cardboard to match the shape of your ribbon backing bar. Slide this DIY backing piece onto the pins inside the shirt before sliding on the metal pin damps (frogs). This distributes the weight of the badges across a larger area of fabric, keeping your shirt perfectly flat and wrinkle-free throughout the duty day.

Wear and Appearance Standards: Authorized Accessories

To maintain the high professional standard of the Class B uniform, you must pay close attention to authorized accessories and wear options.

Ties and Necktabs

The short-sleeve AGSU is typically worn with an open collar, which is the most common warm-weather configuration. However, wearing the Heritage Green necktie (for males) or necktab (for females) is authorized.

• A tie or necktab is required if you wear the AGSU Class B shirt under the AGSU Windbreaker or the Pullover Sweater.
• When wearing the open collar, your undershirt must not bunch or show excessively. You must wear the authorized Heritage Tan 381 crewneck t-shirt. V-neck undershirts are not authorized if they allow the chest to be exposed beneath the open collar.

Headgear Choices

When wearing the Class B AGSU, two primary headgear options are authorized:

1. Garrison Cap: The Heritage Green garrison cap is the standard headgear for this uniform. Enlisted soldiers wear their DUI on the left side of the garrison cap, positioned 1 inch from the front crease and centered vertically. Officers wear their rank insignia in the same location.
2. Maroon, Tan, Green, or Brown Berets: Soldiers assigned to airborne, ranger, special forces, or security force assistance units are authorized to wear their organizational beret with the Class B uniform, complete with their unit's distinct flash and rank or officer insignia.

Frequently Asked Questions About the AGSU Short Sleeve Setup

Can I wear a tie or necktab with the short-sleeve AGSU?

Yes, you may wear the Heritage Green necktie (male) or necktab (female) with the short-sleeve shirt, but it is optional unless mandated by leadership or when wearing the windbreaker or pullover sweater. When wearing a tie or necktab, the top collar button must be fastened, and the tie must be secured with an authorized brass tie clip or clasp.

Are ribbons mandatory on the AGSU short-sleeve shirt?

No, ribbons are optional on the AGSU Class B short-sleeve shirt, though command policies may dictate their wear for formal inspections or specific events. If you choose to wear ribbons, you must wear either your full ribbon rack or a clean "some" configuration (such as your top three awards), provided they are worn in order of precedence and aligned perfectly.

Where do I place the Distinctive Unit Insignia (DUI) on the short-sleeve shirt?

Enlisted soldiers (PV1 to SPC) wear the DUI centered on the shoulder loops of the shirt, while NCOs (CPL and above) and Officers do not wear DUIs on the shoulder loops if they are wearing slip-on shoulder marks. For those wearing slip-on rank, the DUI is worn instead on the Garrison Cap.

How do I prevent badges and nameplates from sagging on the pocketless female shirt?

Use thin cardboard, plastic backer plates, or specialized magnetic uniform backing behind the shirt fabric to distribute weight and keep the accoutrements flat against the body. This prevents heavy metal pins from pulling the lightweight Heritage Tan fabric down, which creates unsightly wrinkles and slants your badges.

What undershirt is authorized with the AGSU Class B?

Only the authorized Heritage Tan 381 crewneck t-shirt may be worn under the AGSU short-sleeve shirt. The collar of the t-shirt must sit snug against the neck without sagging, and it must remain clean, free of stains, and present a highly professional appearance when the shirt is worn open-collar.

Ensure Inspection Readiness with Expert Precision

Setting up your AGSU short-sleeve Class B uniform to exact specifications is a critical skill for every soldier. Taking the extra time to measure, align, and back your insignia ensures that your uniform remains crisp, steady, and inspection-ready throughout long duty days.

Always cross-reference your specific command sergeant major's policy letters, as local command guidelines may dictate specific policies regarding "all, some, or none" ribbon configurations. Keep a backup set of pin backings (frogs) in your desk or vehicle, and use a dedicated uniform ruler before every formations to ensure your presentation remains completely beyond reproach.
