AGSU Short Sleeve Shirt Setup: The Ultimate AR 670-1 Guide

The transition to the Army Green Service Uniform (AGSU) represents one of the most significant aesthetic updates to the United States Army’s heritage in decades. Inspired by the classic "pinks and greens" worn by officers during World War II, the AGSU strikes a balance between historical honor and modern professionalism. Among its various configurations, the Class B variation—specifically featuring the AGSU short sleeve shirt setup—is the go-to choice for daily office environments, warm-weather duties, and semi-formal military settings.

Setting up the Heritage Tan short sleeve shirt requires meticulous attention to detail. Because the Class B uniform does not feature the service coat to hide minor alignment errors, every ribbon, nameplate, badge, and rank insignia is fully exposed to inspection. Deviating even a fraction of an inch from the prescribed Department of the Army Pamphlet (DA PAM) 670-1 standards can result in an unprofessional appearance. This comprehensive guide provides the technical specifications, precise measurements, and expert tips necessary to master your AGSU short sleeve shirt setup.

Understanding the Class B AGSU Configuration

The Class B AGSU uniform relies on the Heritage Tan 565 short-sleeve or long-sleeve shirt worn without the coat. When opting for the short-sleeve setup, soldiers wear the shirt with an open collar, creating a sharp, functional, and breathable profile. Unlike the blue Army Service Uniform (ASU), which utilized pin-on metal rank insignia on the collar for certain ranks, the AGSU shirt utilizes olive-drab shoulder marks (slip-ons) for both officers and enlisted personnel.

The fabric of the Heritage Tan shirt is a durable blend of cotton and polyester, requiring proper pressing and care. Before placing any accoutrements on the shirt, it must be clean, wrinkle-free, and properly ironed with military creases if desired (though modern DA PAM guidelines allow for flat-pressed shirts without heavy creases, many soldiers still prefer the classic crisp look). The "gig line"—the straight line formed by the alignment of the shirt flap, the trouser fly, and the edge of the belt buckle—must be perfectly straight to establish a baseline symmetry for your badges and ribbons.

Understanding where each element goes requires recognizing the structural differences between the male and female shirt designs. The male shirt features functional breast pockets with pocket flaps, which serve as physical anchoring points for measurements. The female shirt, designed for a more tailored fit, does not feature breast pockets, meaning measurements must be taken from fixed anatomical points such as the collar seam and front buttons.

Required Components for the AGSU Short Sleeve Shirt Setup

Before beginning your assembly, gather all the correct components. The AGSU utilizes unique hardware and accessories that differ significantly from the old blue ASU. Using ASU items on an AGSU shirt is a major regulatory violation.

• Heritage Tan 565 Short Sleeve Shirt: Ensure it fits comfortably around the neck and shoulders without bunching.
• Shoulder Marks (Rank Insignia): Slip-on rank insignia matching your current grade, slid over the shoulder loops (epaulets).
• AGSU Nameplate: A matte-finish, brown plastic nameplate with white lettering. The shiny black ASU nameplate is strictly prohibited.
• Ribbon Rack: Your authorized ribbons mounted on a clean, undamaged backing bar.
• Badges: This includes combat and special skill badges (e.g., CIB, Airborne, Air Assault) and marksmanship badges.
• Unit Awards: Positioned on the right side of the chest (for authorized personnel).

Step-by-Step Measurements: Male Setup

For male soldiers, the presence of physical pocket flaps makes centering and aligning your chest items straightforward. However, the fabric can easily shift during pinning, so utilizing a cardboard backing inside the pocket during assembly is highly recommended.

1. Nameplate Placement

The male nameplate must be centered horizontally on the right pocket flap. Vertically, it must be positioned centered between the top of the pocket button and the top seam of the pocket flap. Use a pocket ruler to ensure the distance from the left edge of the plate to the pocket seam is identical to the distance from the right edge.

2. Ribbon Rack Placement

Your ribbon rack is worn centered horizontally over the left breast pocket. The bottom row of the ribbon rack must sit exactly 1/8 inch above the top seam of the left pocket. Ensure the rack is perfectly horizontal and parallel to the pocket line; a sagging ribbon rack instantly detracts from the uniform's appearance.

3. Marksmanship and Special Skill Badges

Marksmanship badges are worn on the left pocket flap. If you wear one badge, center it horizontally on the pocket flap, 1/8 inch below the top seam. If wearing two badges, space them equally across the flap, keeping the 1/8-inch vertical distance from the top seam.

Special skill badges (such as the Combat Infantryman Badge or Airborne Wings) are worn on the left side, centered 1/4 inch above your ribbon rack. If you have multiple skill badges, they are stacked vertically with 1/2 inch of space between them, or aligned according to group precedence as outlined in AR 670-1.

Step-by-Step Measurements: Female Setup

Because the female AGSU short sleeve shirt lacks breast pockets, the alignment of the nameplate and ribbons is determined by the natural drape of the garment and a set distance from the shirt's buttons.

1. Nameplate and Ribbon Alignment

On the female shirt, the nameplate is placed on the right side, horizontally centered. The vertical placement is 1 to 2 inches above the top button, adjusted to fit the soldier’s individual body shape.

The bottom of the ribbon rack on the left side must align horizontally with the bottom edge of the nameplate on the right side. This creates an imaginary straight line running across the bust of the shirt. It is helpful to lay the shirt flat on an ironing board, use a long ruler to align both pieces, and pin them in place before trying the shirt on for final adjustments.

2. Badge Placement

Without pocket flaps to guide placement, marksmanship badges on the female shirt are pinned below the ribbon rack. They must be centered horizontally below the ribbons, with the top of the badge or clasp mount sitting exactly 1/4 inch below the bottom of the ribbon rack. Special skill badges are placed centered 1/4 inch above the ribbon rack, matching the vertical spacing rules of the male setup.

Pros and Cons of the Class B AGSU Wear

While the Class B AGSU short sleeve shirt setup is highly practical, it has distinct advantages and challenges compared to the full Class A (jacket-on) setup.

Pros

• Exceptional Warm-Weather Comfort: The Heritage Tan 565 fabric is breathable, making it much more comfortable during summer months or in tropical duty stations than the heavy service coat.
• Ease of Movement: Without the constriction of the service coat, soldiers enjoy a full range of motion, which is ideal for administrative tasks, briefings, and desk work.
• Cost-Effective Presentation: For daily duties that require a professional appearance but do not mandate Class A attire, the Class B setup minimizes wear and tear on the expensive AGSU coat.

Cons

• High Visibility of Errors: The absence of a jacket means every badge, ribbon, and crease is on display. Any slight misalignment, lint, or loose thread ("bullet holes" or frayed edges) is immediately obvious.
• Frequent Maintenance Required: The Heritage Tan shirt wrinkles far more easily than the poly-wool blend coat. Sitting in an office chair or driving a vehicle can rapidly crease the back of the shirt, requiring daily ironing.
• Accoutrement Transfer: Constantly moving ribbons and badges from the coat to the shirt can damage the delicate fabrics over time if not done carefully.

Expert Tips for a Flawless Presentation

Having served under inspection conditions, seasoned non-commissioned officers (NCOs) know that paper measurements are only half the battle. To achieve an inspection-ready look, consider these professional tips:

• Use Cardboard Backings: Pinning badges directly to shirt fabric causes sag. Cut small rectangles of thin, sturdy cardboard (or expired plastic cards) and place them on the inside of the shirt before pushing the pin clutches on. This keeps the fabric taut and prevents badges from drooping forward.
• Invest in a Alignment Tool: Acrylic uniform alignment rulers are inexpensive and invaluable. They feature pre-cut slots for 1/8-inch and 1/4-inch measurements, allowing you to set up your shirt in minutes without guessing.
• Pre-Fit Your Shoulder Marks: Ensure your slip-on shoulder marks fit snugly on the epaulets. If they slide around or hang off the edge of the shoulder, use a small, discreet safety pin underneath or hook-and-loop tape to keep them anchored flat against your shoulder.
• Maintain the Gig Line: Your belt buckle must be polished, and the brass edge must line up perfectly with the fabric fold of your shirt and the seam of your trousers. Check this every time you stand up.

Frequently Asked Questions (FAQs)

Can I wear a tie with the AGSU short sleeve shirt?

Yes, but it is optional. When wearing the short-sleeve shirt without a tie, the collar is worn open. If you choose to wear the olive-drab necktie (for males) or neck tab (for females) with the short-sleeve shirt, you must wear all other Class B accoutrements, and the shirt must be buttoned completely to the top.

Are collar brass or branch insignia worn on the AGSU short sleeve shirt?

No. Unlike the older green Class B shirts, branch insignia (such as Infantry crossed rifles or Quartermaster wheels) and "U.S." insignia are never worn on the AGSU shirt collars. These items are strictly reserved for the AGSU Service Coat.

Do I wear my unit crests (DUI) on the AGSU shirt?

Distinctive Unit Insignia (DUIs) are not worn on the shirt collars or pockets of the AGSU short-sleeve shirt. They are worn on the shoulder loops of the AGSU coat, or on the black pullover sweater if configured as part of your Class B options.

What undergarments are authorized with the short sleeve shirt?

Soldiers must wear an authorized t-shirt underneath the Heritage Tan shirt. This must be a crew-neck t-shirt in either white or tan, matching the fabric style authorized by your unit leadership. V-neck t-shirts are not permitted if they are visible when the collar is worn open.

Can I wear foreign badges or unit awards on the Class B shirt?

Generally, yes, provided they are authorized under AR 670-1 and registered in your official military records. However, because space is limited on the shirt and a crowded shirt can look cluttered, many soldiers choose to wear only their primary U.S. awards and badges on the Class B, reserving foreign decorations for the Class A coat.

Elevate Your Military Presentation

A crisp, perfectly aligned uniform is the first indicator of a disciplined soldier. Do not let a poorly measured nameplate or a sagging ribbon rack undermine your hard work and professional stature. Take the time to measure twice, pin once, and inspect yourself in a full-length mirror before stepping out.

If you are prepping for an upcoming promotion board, a change of command, or daily duty, invest in high-quality uniform tools, fresh backing boards, and pristine AGSU accoutrements. Ensure your presentation reflects the high standards of the United States Army. Speak with your unit supply sergeant or visit your local military clothing sales today to upgrade your uniform kit.
