This one is a US pin..
It's wright IN UNITY WE BUILD.
The mark is A.N.DONDERO.INC. WASH. D.C. D 2

Of what division is it?

Hi, I have corrected the title and moved your post to the correct forum.

There are many hundreds of different designs of US Distinctive unit insignia. Worn on the lower lapels of the tunic. This is not for a division but is for a smaller unit, like a Regiment.

No idea on the unit sorry.

Cheers, Ade.

It's from the 366A ENG Bn US Engeneers.
Here's a link for ID the badges for the US engeneers 3rd Page down on the right side in the middle ( http://www.coleccionesmilitares.com/...texto/USAm.pdf )
