Identify Red Arrowhead medal?

[Vintage]

I found this with my Dad's old medals. Everything else was easy to identify and was Army / Army Air Corps from the WWII era.

There are no markings. At first I thought it was a heart, but it does look much more like an arrowhead.

I guess there is a chance it is non-military... but as I said, everything else in the box was from his uniforms.

It would be great if someone could help me identify this!

 

Thanks,
