I served in the Army and I have several nice pins from my former units, cap and hat bagdes, collar brass and MOS/corps. pins that would work very well on an Army or AmHeritage kilt. I you were in the service, you should really consider using that kilt as a way to show pride in your veteran status. If you did not serve, then I think the US seal or Flag are really nice. Ive never seen a Statur of Liberty pin that would fit the bill, but I think that sounds like a nice idea too.

I think my next kilt might be an AmHeritage.
