Is This A Union Pioneer?

This image was posted on a French website two years ago. Does it show a Union Pioneer from the Civil War or a French Pioneer? If yes, can anyone identify the insignia being worn?

Not sure but looks like it... very nice photo!

Do I see a "CO" "E"?

No positive identification of the insignia has been made that I know of.

I think he's French instead of US. The epulatte isn't like one I've seen on a US jacket.
