Im searching for information on both of these companies, mainly the 624th Medical Clearing Company, (what army they were in, what corp, and who they were attached to at different times) but any info about these companies would help tremendously since my grandfather has now past away and i would like to find out as much information as possible. I know these two companies were in the Battles of Ardennes, Rhineland, and the Central European Campaign. My grandfather at the time of his discharge in 1946 was part of the 624th Medical Clearing Company. If anybody has any information about these two it would be greatly appreciated. And also i would like to know what "Clearing Companies" and "Medical Clearing Companies" done (what there roles were etc..)

Thank You in advance for any information you can provide.
