How do you find a list of Silver star winners for the Vietnam war?
No such list exists.
There, are, however, some re-created lists by unit. Many units have
organized reunion associations, where Medal of Honor, Distinguished
Service Cross, and Silver Star honorees are listed. Check the
division organization the individual served with.
B.G. Burkett in his book, Stolen Valor, lists all Vietnam Medal of
Honor, Distinguished Service Cross, Navy Cross, Air Force Cross,
and returned Prisoners of War.
