Bronze Stars were awarded for either meretorious service over a certain period of time or for heoric acheivement in an action against the enemy. The herois acheivement was supposed to come with a V device on the ribbonThe event is noted.
I don't what unit might give the award. The one I know about was to a man who was always with a TD battalion but his came from V Corp. The battalion was a member of V Corp.
The V was omitted from my husband's ribbon. I received it by wr1ting -- Department of the Army U.S. Army Human Rescources Command. 200 Stovall St. Alexandria, VA 22332-0400
Send them copies of all the info you have re your request.
It took about three months to receive the V.
