Army Green Service Uniform (AGSU) Regulation: Complete AR 670-1 Compliance Guide

Getting the AGSU wrong is not just an inspection problem. It can follow you. A misplaced nameplate, an unlaced badge, or the wrong shade of brown on your shoes signals to everyone in the room that something is off.

The problem is that AR 670-1 runs hundreds of pages, and most soldiers just need a clear answer: what do I wear, where does it go, and what will get me flagged?

This guide covers all of it, every required component, exact placement rules, grooming standards, and what the 2027 mandatory transition actually means for you.

What Is the Army Green Service Uniform?

The Army Green Service Uniform, commonly called the AGSU or "pinks and greens," is the U.S. Army's standard professional duty uniform. It replaces the Army Service Uniform (ASU) for daily wear and is governed by Army Regulation 670-1 and DA Pamphlet 670-1.

Designed to echo the World War II-era officer's uniform, the AGSU uses a heritage green service coat paired with heritage taupe trousers. The look is intentional: it connects modern soldiers to the Army's history while projecting a sharp, professional appearance in office and ceremonial settings.

It is not a combat uniform. Operational environments still call for OCP. For a deeper look at the history behind the design, see our article on whether pinks and greens are replacing dress blues.

Is the AGSU Mandatory in 2027?

Yes. Starting October 1, 2027, the AGSU becomes the mandatory daily duty uniform for all soldiers across active duty, Reserve, and National Guard. This was confirmed in Army Directive 2020-08, which established the phased transition timeline.

What changes on that date:

• The AGSU becomes the primary service uniform for all professional environments
• The Army Service Uniform (ASU) shifts to formal and ceremonial occasions only
• Every soldier must own a complete, regulation-compliant AGSU

If you do not have one yet, now is the time to get ahead of it, not the week before the deadline.

Complete AGSU Components Required by AR 670-1

Every item below is required for a regulation-compliant Class A appearance. Missing one component is enough to fail an inspection.

Core Uniform Items

• Heritage green service coat (Male jacket / Female Eisenhower jacket)
• Heritage taupe trousers (Male trouser / Female trouser)

Khaki shirt, short or long sleeve (Male enlisted long sleeve / Male officer long sleeve / Female tuck-in blouse)

Required Accessories

• Brown necktie or neck tab
• Brown leather belt with brass buckle
• Brown oxford dress shoes (Men's / Women's)

Garrison cap or service cap

Authorized Optional Items

• Eisenhower jacket, when authorized by unit (see male jacket link above)
• Windbreaker
• Leather jacket
• Cold-weather items when conditions warrant

The difference between Class A and Class B is straightforward. Class A includes the service coat and is worn for ceremonies, inspections, and formal duties. Class B, without the coat, is standard for everyday office work.

AGSU Nameplate: Exact Specifications

The nameplate is small, but it is one of the first things an inspector checks. Get it right.

• Size: 1 inch x 3 inches
• Color: Dark brown with taupe lettering
• Finish: Laminated

Wear it on the service coat, shirts, and Eisenhower jacket, centered above the right breast pocket, level with the top button. Do not wear it on the leather jacket, windbreaker, or all-weather coat.

Insignia and Badge Placement Rules

This is where most AGSU errors happen. The tolerances are tight, and eyeballing it rarely works.

Rank insignia: centered on shoulder loops, no exceptions. You can find Army enlisted metal chevrons and officer rank insignia in our uniforms section.

Ribbons: placed above the left breast pocket. If you are wearing a combat badge, it goes 1/8 inch directly above the ribbons. See our ribbon bar mounts and accessories for regulation-compliant mounting options.

Unit insignia: on the sleeves, per your unit's designation.

Nameplate: right chest, centered, level.

The spacing between items matters as much as their position. A ribbon rack that is slightly off-center or a badge that is 1/4 inch too high will be noticed. Use a ruler during prep, not just during the inspection.

Grooming Standards Under AR 670-1

A regulation uniform on a soldier who does not meet grooming standards still fails. Both work together.

For male soldiers:

• Face clean-shaven, or mustache neatly trimmed (mustaches may not extend past the corners of the mouth)
• Hair conservative, tapered on sides and back
• No extreme styles, lines, or unnatural colors

For female soldiers:

• Hair neat, conservative, and not interfering with headgear
• Braids and natural styles are authorized when they meet neatness standards

Exceptions: Religious accommodation and medical profiles are authorized under AR 670-1. The Army's personnel policy portal outlines how soldiers can access guidance on exemptions and accommodations. Soldiers with approved exceptions are still expected to maintain the neatest possible appearance within those allowances.

When to Wear the AGSU

The AGSU is designed for professional environments, not the field.

Appropriate settings include office and administrative duties, briefings and meetings, official travel, and ceremonies where the ASU is not specifically required.

It is not worn for field operations, physical training, or combat environments. OCP remains the uniform for those. When your unit does not specify, the default is AGSU for anything professional during duty hours.

AGSU vs. ASU: What’s the Difference?

This question comes up constantly, especially as the 2027 transition approaches.

The ASU, the familiar blue dress uniform, remains the Army's formal and ceremonial uniform. It is not going away. What changes is its role: after 2027, it is worn for dress occasions like official ceremonies, formal events, and situations that specifically require it.

The AGSU takes over everything else, daily duty wear, office environments, official travel, and the majority of professional settings soldiers navigate week to week.

Think of it this way: the ASU is your formal suit. The AGSU is what you wear to work. If you are building out your complete uniform setup, browse the full Army Green Service Uniform collection to make sure nothing is missing.

Common AGSU Mistakes (and How to Avoid Them)

Most AGSU failures are not dramatic. They are small oversights that compound.

Insignia placed by feel, not measurement: Use a ruler. The 1/8 inch spacing above ribbons is not approximate.

Wrong shade of brown: Belt, shoes, and tie must match in shade. The "close enough" approach does not survive a close inspection.

Wrinkled coat or trousers: Press them the night before, not the morning of. Fabric that has been hanging all night lays flatter.

Unpolished shoes: Brown leather dulls quickly. Keep edge dressing and polish on hand. Angelus shoe paste is a widely used option for maintaining the correct finish on brown dress leather.

Missing nameplate or wrong specs: Verify size and finish before any inspection, not during.

Pre-Inspection Checklist

Run through this the night before, not five minutes before formation.

• Coat and trousers pressed and lint-free
• Nameplate centered, level, correct specs
• Ribbons aligned above left pocket
• Combat badge (if applicable) 1/8 inch above ribbons
• Rank insignia centered on shoulder loops
• Belt, shoes, and tie matching in brown shade
• Shoes polished and edges dressed
• Hair and grooming within AR 670-1 standards
• Garrison or service cap in serviceable condition

Conclusion

The AGSU is not a complicated uniform. It rewards soldiers who pay attention to small details and prepare consistently, and it shows on every soldier who cuts corners.

With the 2027 mandatory transition now firmly on the calendar, there is no practical reason to delay getting compliant. Know your components, verify your placement measurements, maintain your grooming standards, and run through the checklist before every inspection. That covers the vast majority of what gets soldiers flagged.
