What is the uniform this NCO is wearing at the Fort Moore Redesignation Ceremony?

This Soldier is a member of the US Military Academy Band. All three of the Army's Special Bands, i.e., The US Army Band "Pershing's Own," The US Army Field Band, and the USMA Band, wear similar tunics. The quickest way to tell them apart is by looking at their stripes. TUSAB wears inverted (point down) stripes on their ceremonial uniform, the USMA stripes are white, and TUSAFB wears the same stripes that are on the Army Blue Uniform.

At first glance I thought it was a soviet soldier, but what do I know. I served at three bases, Jackson, Polk and Benning and I'll go to my grave calling them correctly. I was born in the North and my direct great grandfather fought for the North yet if you search the last name many Grindstaff's fought for what they thought was right, the south. Cancel culture is destroying this country.

Seems appropreate to wear a uniform not recognised. Same like naming Fort Benning to satisfy some BS woke agenda

At first I'm thinking stolen valor because it looks like a cross between an Army and Marine uniform, and that's just weird, But I did look it up. West Point Band. I guess they don't get the red hat and upside down NCO rank in that band? Glad that got pointed out because that one looked a little tricky. You don't see that one everyday, except maybe at the football game when Army is getting Navy's goat. (at the 1 yard line)

Looks like a Band Uniform.

Perhaps a band uniform?

The uniform is a band member, or member of an Army choir. Look closely at the insignia on the hat!

It looks to me like an Army ROTC Cadet uniform, possibly of a band member.

It’s the Army Band dress uniform

It's a bandsman uniform.
