Party in 1939 at the same time that the political leadership ranks were expanded into their final form. The purpose of the armband system was to denote positional titles within the Nazi Party in contrast to a party member's political rank. There were three groupings of armbands, classified as "operational", "administrative", and "command". The operational armbands were used by Nazi Party political leaders on the local and county levels and were worn by those Party leaders directly engaged in implementing Party policies to the public. During World War II, this was most often associated with food rationing, war relief efforts, and civil defense. The administrative armbands were worn by office staffs across all levels of the party, although mostly were used by the regional staffs of the Gauleiters. The third, and least common of the armbands, were the command armbands worn by the Deputy Gauleiters, Gauleiters, and Reichsleiters. The Nazi Party armbands were intended for immediate implementation upon the outbreak of World War II in 1939, although it was not until 1943 that the system was in total effect. Even then, photographic evidence reveals it was not uncommon for some political leaders to simply wear the pre-1939 bare swastika armband, with some photographs as late as 1945 revealing political leaders failing to wear the appropriate Nazi positional armband. By pairing up a wearer's political collar tabs and armband, it was possible to determine exactly what their position and responsibilities were within the Nazi Party political leadership corps; the armband system was also used to differentiate between Party leaders who may have held the same political ranks but were entrusted with vastly different responsibilities. For instance, a Hauptbereichsleiter who was serving as the Kreisleiter of a German county, would wear a more elaborate armband than a Nazi Party member of the same rank who was on the administrative staff of a Gauleitung. On the local level of the Nazi Party, political armbands were often used to denote those Nazis holding the positions of Blockleiter and Zellenleiter. A further political position, unique only to the local level of the Nazi Party, was that of Betriebsobmann, which was a type of Shop Steward position. At the top tier of the operational armbands was a unique armband worn by both the Ortsgruppenleiter and the Kreisleiter Administrative armbands were used across all levels of the Nazi Party, beginning with the position of Mitarbeiter, which was
