Army shirts go by official names like combat uniform coat, Army combat shirt, and service shirt, depending on duty and dress.
Asking what are army shirts called? sounds simple, yet the name shifts with the job. In the field, the top is the combat uniform coat. Under body armor, Soldiers swap to the Army combat shirt. For garrison and ceremonies, the Army wears the tailored service shirt in the Army Green Service Uniform (AGSU). The sections below break down each term, when it’s correct, and how to spot the right piece fast.
Quick Reference: Common Army Shirt Names
This broad table clears up the naming at a glance. It lists the official item name, where it’s used, and what stands out.

| Service Shirt, Heritage Tan (AGSU) | Garrison/Class B | Light brown dress shirt; short or long sleeve |
| Aircrew Combat Uniform Shirt | Flight operations | Cut and fabrics tailored for aviation tasks |
| Maternity Work Uniform Coat | Issued for duty wear | Part of the authorized maternity work uniform set |
| Legacy BDU Coat | Historical reference | Earlier camouflage “coat” replaced by the ACU |
What Are Army Shirts Called In Different Settings?
Regulation language uses clear buckets. Field clothing falls under the combat uniform, and the top garment there is the coat. Dress and garrison outfits rely on service shirts. Specialized teams have purpose-built shirts named for the mission. That’s why you’ll hear multiple terms in one unit on the same day.
Field Duty: The Combat Uniform Coat
The current field uniforms are the Army Combat Uniform (ACU) and the Improved Hot Weather Combat Uniform (IHWCU). In regulation, the combat uniform’s composition begins with “coat,” then trousers and the rest of the set. The coat carries the name and service tapes, rank, and authorized badges. When sleeves are rolled, leaders decide whether the camouflage faces out or in. That “coat” wording is straight from the rulebook, not a nickname. You’ll still hear troops and surplus shops say “blouse,” but in official writing the term is coat. (See the composition and sleeve guidance in the Army’s uniform regulation.) AR 670-1, Combat Uniform section.
Under Armor: The Army Combat Shirt
Armor adds heat and friction. The Army combat shirt fixes both with a breathable, flame-resistant knit torso that sits flat under plates. Sleeves are woven in camouflage for durability, pockets, and protection. Soldiers wear it in place of the coat under armor to cut bulk and stay cooler on long movements. Official program notes explain that the ACS is designed specifically for wear under body armor. PEO Soldier: Army Combat Shirt.
Office And Ceremonies: The AGSU Service Shirt
Outside the field, the Army Green Service Uniform uses a tailored service shirt in Heritage Tan, available in short- and long-sleeve versions. Worn without the coat, this setup is often called “Class B.” With the Heritage Green coat and accessories, it becomes “Class A.” The shirt pairs with a tie when long sleeves are worn. Program materials list these shirts among the AGSU clothing bag items. PEO Soldier: AGSU.
Why People Say “Blouse”
Troops and many surplus sellers use “blouse” as shorthand for the field top. That jargon traces to earlier uniform tunics and lived on through the BDU era. In current policy, the official word is coat. If you’re writing for a general audience, “field jacket” can mislead, since that often points to outerwear like the M-65. For accuracy, use combat uniform coat for the camouflage top and reserve “jacket” for outer layers.
Army Shirt Names And When To Use Each
Context drives the name you pick. Here’s how the Army pairs shirts with tasks on a typical training day and work week.
Range Day Walkthrough
Form up and brief in the ACU coat. Armor up for live-fire in the Army combat shirt. Break down and police brass back in the coat once armor comes off. Same Soldier, two different shirt names, both correct for the moment.
Garrison And Travel
On a normal duty day, leaders set the uniform of the day. That could be Class B with the AGSU service shirt or the ACU coat for tasks that head outdoors. For commercial travel, the combat uniform is allowed in some cases; ceremonies and formal events call for service wear. The uniform regulation spells out those occasions and restrictions.

Details That Distinguish Each Type
Combat Uniform Coat Features
- Operational Camouflage Pattern (OCP) is the current issue pattern.
- Lay-flat collar on the IHWCU; earlier cuts may use a stand collar.
- Chest and sleeve pockets sized for notebooks, pens, and small gear.
- Hook-and-loop fields for rank, tape, and authorized badges.
- Roomy cut for mobility and layering in cold weather.
Army Combat Shirt Features
- Breathable knit torso to reduce heat under plates.
- Flame-resistant materials for operational safety per issue specs.
- Woven sleeves with camouflage, pockets, and elbow reinforcement.
- Quarter-zip or crew neck depending on the model and contract.
AGSU Service Shirt Features
- Light brown Heritage Tan fabric with a clean, pressed look.
- Short- and long-sleeve versions for climate and dress level.
- Paired with a tie on long sleeves; without the coat it’s “Class B.”
- Badge and nameplate placement follows AGSU diagrams.
Official Terms In Black And White
The Army’s uniform regulation lists the combat uniform coat as part of the combat uniform’s composition and outlines sleeve-rolling guidance. Program Executive Office (PEO) Soldier’s portfolio explains how the Army combat shirt is worn under body armor and why its materials differ from a normal coat. The AGSU portfolio lists the Heritage Tan shirts among clothing bag items. These three sources anchor the naming used across the force: AR 670-1 and PEO Soldier equipment pages.
Legacy Terms You’ll Still Hear
The older Battle Dress Uniform (BDU) used the term coat for its top. The ACU replaced the BDU, and the official wording stayed consistent. That’s why you’ll still see “BDU coat” in catalogs and surplus listings. It’s the same naming pattern, just tied to an earlier issue. You might also see specialty pieces such as the Ballistic Combat Shirt used with newer armor systems; its name tells you it adds ballistic fragmentation protection beyond the standard ACS.

Care And Wear Tips That Keep You Correct
Label Check
Uniform labels spell out the garment name and care. If the tag reads “coat, combat uniform” or similar, it’s the field top. If it reads “Army combat shirt,” follow the knit-torso care instructions to protect the flame-resistant fibers. For AGSU, check the tag for sleeve type and press accordingly.
Match The Set
Don’t mix IHWCU outer pieces with ACU outer pieces. Wear the coat and trousers from the same system. That keeps the cut and fabric consistent and follows current guidance set in the regulation.
Badges And Tapes
On the coat, tapes and insignia are either all sewn or all pinned; mixing isn’t authorized. On the service shirt, nameplates and badges follow AGSU diagrams. When in doubt, consult the current diagram set listed on program pages or in the regulation chapters for your uniform.
Answering The Exact Question
If a reader asks, “what are army shirts called?” you can answer cleanly with this: field wear uses the combat uniform coat; under armor is the Army combat shirt; and dress wear uses the AGSU service shirt. That line covers daily duty, armor, and garrison wear in one go.
Key Takeaways You Can Use
- Say “combat uniform coat” for the camouflage top in the ACU or IHWCU.
- Say “Army combat shirt” for the knit-torso top worn under armor.
- Say “service shirt” for the AGSU Heritage Tan shirt in Class B.
- “Blouse” is common slang; “coat” is the official term in current policy.
Now you’re set to use the right name in any setting, and your wording matches Army sources line for line.
