rookie needs help finding this brooch

[OC Richard]

The closest uniform I know of is of the Irish Air Corps Pipe Band



And Irish Defence Forces Pipe Bands





(Note we're seeing three styles of jacket and three styles of headdress, I don't know how many Pipe Bands the Irish miltary has, or what their specific uniforms are.)

Those are HUGE penannular brooches! Twice the size of what I usually see.

Here's a video of an Irish Defence Forces Pipe Band
