In looking through my Medics photos for Legionnaire B's site thread, I noticed that I had a couple that had the oval sleeve badge on them. I vaguely recall thinking these were established @ 1916 but in looking at my reference materials I can not find when or what they were. They show up, are mentioned casually here and there, but I can't find a chart or listing of them. I know there was a MG badge and a signals one and I think this astulapstab abzeichen means veterinarians/medics section,-but are there any others? I'd be grateful for any information. Ta,
