Need help identifying a WWII lapel pin

[RTicUL8]

This is the only picture that I have of my grandfather in his uniform.
He was a supply officer stationed at Fort Custer (Kalamazoo, MI) during WWII.
I do not know what Army unit he was assigned to.

In this picture he has a Lieutenant bar; He was promoted to Captain shortly thereafter.

What I need help with identifying the pin on his lapel.
It almost looks like a butterfly.

I've spent hours searching sites for WWII army pins and insignias with no luck.

Any help would be appreciated.

It almost looks like the crossed pistols emblem of the Military Police.

That's what I was thinking.

Found it HERE.
Looks like it may have a unit designator on it.

I was also looking at wikipedia on Fort Custer and they said the primary function of the fort druing WWII was a Military Police Replacement Training Center. http://en.wikipedia.org/wiki/Fort_Custer

It does look like the "Branch Insignia".

Here's a modern day set-up. I'd say it's definitely MP in your picture:

Yes, he was MP.

His primary duty though was being in charge of supplies for the fort.
He did tell me that others in his unit would watch German POWs.

It kind of does look like two pistols, but there's something like the letter M above it. I wonder what that is?

Yeah, I fooled around with the picture some; changing the brightness and contrast, and it does look like an "M".

What's higher up on the lapel? It looks like a UA, not the U.S. I would expect.

210th MP BAT:

Yeah, it sure doesn't look like US. More like UA or UR as posted above.

Family members helped.

He was in the 701st Military Police Battalion, company B.

FYI: The 701 is the Army's oldest military police battalion - Activated Feb 1 1941.

Neat.

The upper lapel brass is a "U.S." - it just looks funny from the lighting. If you look, you can see the lower crossbar of the "S" in the picture after all, and it just seems to be shaded somewhat.
