I am a Vietnam Vet and whenever I come to a site like this tears come to my eyes I think of the ones who did not come home. I spent two years in Nam and was assigned to many different Army units.If you are looking to find people who were in Vietnam and know the unit they were assigned to simply type in the unit on the key word search. I have found my units such asF Troop 17 Cav. 196 Light Infantry America, Co C 87 Inf, 92 and 95 Mp Bn. by doing this and was able to make contact with many of my old puddies. If you only know the Division such as 1st Cav or 1st Div this will work also it may take you longer but it will work. I have also went to a site were you find your classmates these is also a section there for just this type of searching. If I can help any anyway I will do what I can please notice my knowledge is mainly with the Army units. please email me.
