How do you find a list of Silver Star winners in the Vietnam War?

I am a Silver Star winner from the Vietnam War. It is on 1st Aviation Brigade, APO San Francisco 96307.

General Orders Number 2554

Dated 14 June 1967

Date of action: 31 January 1967

This is not so much a improvement but a extention of above. Most units have web sites and list Silver Star recipients. As I was with the 173rd AIB and the 11th ACR, both have list of MOH,DSC and Silver Stars awarded.Names, rank and dates are provided. Bronze Stars and Purple Hearts were so numerous, it was decided not efficient to list.
