 FACT: Schulz is identified as a Feldwebel or Sergeant but he is  wearing the rank insignia of an Unteroffizer or Corporal. The  German Armys rank insignia were on the shoulder straps. A  Feldwebels insignia would be lace that went around all edges of  the shoulder strap plus a star or pip on the strap. Schulzs  shoulder straps do not have lace at the bottom of the strap nor do  they have have stars; that is the insignia of an Unteroffizer.
