Got done watching the last half of the ND-Navy "Irish classic" on CBS and they showed a couple of shots of 3-4 young men standing on the side of the field in colonial style redcoats with navy blueish great kilts.

I'm assuming they were with the Navy, as I doubt the kilts are a ND tradition, but does anyone know anything more about them? Is this a regular navy tradition?

Sadly I didn't get a pic.
