This may be a bit late to respond, but there is a website by the government that has a lot of this information. Can't remember what it's called, but there is a link for it on www.65thSignalBattalion.com
, under "Links", that will take you to it. We have several campaign medals/ribbons from WW II for grandfather and grandmother, who both served, and there is a neat page that shows all the campaign medals from at least the Civil War. Grandmother was in the Pacific Campaign as a nurse in the ANC (Army Nurses Corp)--different from the WACs, I think. She served in a field hospital on New Guinea in the South Pacific.
