Changes are coming, and so is an updated Army Regulation 670-1 (Wear and Appearance of Army Uniforms and Insignia). For those who aren’t familiar, the AR 670-1 is like the Bible of military appearance. It details, to the fraction of an inch, the wear of the uniform, the placement of badges, patches, and awards. It dictates all the standards for what is — and more importantly, what is not — allowed in uniform. Have a question about how to trim your mustache? 670-1. Want to know what color socks to wear? 670-1. It’ll even help you know how to trim your fingernails the Army way.

In short, if it’s not in AR 670-1, it’s not authorized.

That’s why the recent announcement of changes to the regulation has so many people up in arms. After all, this isn’t just a little memo about hairstyles, this is a rewrite of the text that dictates the look and feel of the entire U.S. Army.

Revised Army regulation and grooming standards support diversity, equity, and inclusion, and prioritize people.
