My father-in-law was a member of the 363D Engineer Special Services Regiment during WWII. I am finding it very difficult to find any kind of unit insignia / patch for his regiment and may indeed not know exactly what to look for. Based on his discharge papers, I have identified his badges and medals and the red and white patch with the "castle" on it. But in some of my researching, I have seen a patch with an elephant on it and the words "ALLONS NOUS" and a notation calling the group "San Francisco's Own," although I can find nothing to do with San Francisco and his service. Would also love to find out what, in particular, his particular regiment was involved with in the Persian Gulf.
