Understanding U.S. Army Branch Insignia: A Complete Guide
Every U.S. Army officer and warrant officer wears a small but historically significant device on their uniform collar: their branch insignia. These devices identify the soldier's branch of service — Infantry, Artillery, Signal Corps, Medical Corps, and dozens more — and carry heraldic traditions that in some cases date back to the Civil War era. This guide explains what branch insignia are, how they're worn, and what the symbols mean.
What Is Branch Insignia?
Branch insignia (also called branch of service insignia or branch devices) are metal devices worn on the uniform collar that identify a soldier's branch of the Army. Each branch has its own unique device, approved by The Institute of Heraldry (TIOH), with specific heraldic meaning tied to the branch's mission and history.
Branch insignia are worn by:
- Commissioned officers — on both collar points of the Army Service Uniform (ASU) jacket
- Warrant officers — on the left collar point (right collar bears the warrant officer eagle device)
- Some enlisted soldiers — in specific ceremonial or dress uniform contexts
Key Branch Devices and Their Meaning
Here are some of the most recognized Army branch devices and the history behind them:
Infantry — Crossed Rifles
The crossed Springfield rifles have identified Infantry soldiers since 1875. The design references the primary weapon of the foot soldier and is one of the most recognized military symbols in American history. The Infantry branch colors are Blue and Silver.
Artillery — Crossed Cannons
Crossed field artillery pieces have identified the Artillery branch since the Civil War era. The design reflects the branch's historical role as the "King of Battle." The Artillery branch colors are Scarlet and Yellow.
Armor — Crossed Sabers with Tank
The Armor branch device combines the cavalry saber (inherited from the old Cavalry branch) with a tank, reflecting Armor's dual lineage as both a mounted and mechanized force. The Armor branch colors are yellow and black.
Signal Corps — Crossed Signal Flags with Torch
The Signal Corps device features crossed signal flags (representing visual communications) with a flaming torch (representing the transmission of knowledge and information). Branch colors: Orange and White.
Medical Corps — Caduceus
The caduceus — a staff entwined by two serpents — is the universal symbol of medicine and has identified Army medical officers since 1902. The Medical Corps branch colors are maroon and white.
Corps of Engineers — Castle
The turreted castle has symbolized military engineering since medieval times and was adopted by the U.S. Army Corps of Engineers in 1840. It remains one of the oldest continuously used military symbols in the American Army. The Corps of Engineers branch colors are scarlet and white.
Judge Advocate General's Corps — Crossed Pen and Sword
The JAG Corps device features a crossed pen and sword, representing the dual nature of military law — the force of arms and the rule of law. The Judge Advocate General's Corps branch colors are dark blue and silver.
How Branch Insignia Are Worn on the ASU
On the Army Service Uniform (ASU):
- Worn on both collar points of the blue ASU jacket
- Centered on the collar, with the bottom of the device approximately 1 inch from the front edge and 1 inch from the bottom edge of the collar
- Must be the correct finish — officers wear gold-colored branch devices; the finish must meet Army manufacturing specifications
- Worn in addition to (not instead of) rank insignia, which appears on the shoulder boards
Branch Insignia vs. Branch Plaque vs. Regimental Crest
These three devices are distinct and serve different purposes:
- Branch insignia — Identifies the soldier's branch of service. Worn on the collar.
- Regimental crest — Identifies the soldier's regimental affiliation under USARS. Worn on the lapels.
- Unit crest (DUI) — Identifies the specific unit the soldier is assigned to. Worn on the shoulder loops.
All three may be worn simultaneously on the ASU — each serves a distinct heraldic and regulatory purpose.
