Info on macv

I have been trying to see exactly where my dad was at in vietnam. As far as I know, he was in the United States Military Assistance Command Vietnam in Cam Rahn Bay during the tet offensivw. He may have also been in the 32nd Medical Depot, but i'm not sure on that. I just wanted to see any kind of record of this. His name is Adolfo Moran Saldivar. If anyone knows anyway I can get info on this, I would greatly appreciate it.
