More on Squads and Messes

[debwallsmith]

I think I have already asked this question but I can't find the thread. Apologies. Besides numerical Squads and Messes there are several letter designations: CH, CHN, DC, DD, HC, HD, HN and Hosp. I'm going to assume that "hosp" means the individual was actually being treated at the hospital. If "CH" refers to Camp Hospital, is this a different designation than "hosp" or is it just the way it was recorded? Can it be assumed that "CHN" = "Camp Hospital Nurse" and "HN" = "Hospital Nurse"? Does this indicate that prisoners were working as nurses in both the camp hospital as well as the hospital for the CSA prison employees? Finally, I have absolutely no ideas on "DC", "DD" "HC" although I could be convinced that "HC" is just a transcription error of "CH". Any thoughts? If anyone has any sources I could cite, that would be great. @Gary Morgan - ideas?

Thanks again. I'm trying to keep my questions to a minimum but occasionally I simply can't find a source for this information.
