The uniforms and insignia of the Sturmabteilung (SA) were Nazi Party paramilitary ranks and uniforms used by SA stormtroopers from 1921 until the fall of Nazi Germany in 1945. The titles and phrases used by the SA were the basis for paramilitary titles used by several other Nazi paramilitary groups, among them the Schutzstaffel (SS). Early SS ranks were identical to the SA, since the SS was originally considered a sub-organization of the Sturmabteilung. Origins of SA titles (1921–1923) The brown shirted stormtroopers of the Sturmabteilung gradually come into being within the Nazi Party beginning in 1920. By this time, Adolf Hitler had assumed the title of Führer of the Nazi Party, replacing Anton Drexler who had been known as the more democratically elected Party Chairman. Hitler began to fashion the Nazi Party on fascist paramilitary lines and, to that end, the early Nazis of the 1920s would typically wear some sort of paramilitary uniform at party meetings and rallies. The most common of these were World War I uniforms with full medals. Also common were uniforms of the Freikorps as well as uniforms of veteran groups such as Der Stahlhelm. Nazi Party members would also mix components from all three types of uniforms with little to no standardization except a swastika armband worn on the left arm. By 1921, the Nazi Party had taken its "Sports Detachment", consisting mostly of bodyguards Hitler used for his own protection, and had formed the Nazi stormtroopers, or the "Storm Detachment", which was shortened to be known as the SA. It was at this point that the very first SA titles came into being, although there were no established uniforms or insignia except a swastika armband worn on a paramilitary uniform. At the start of the group's existence, the SA had four primary titles: Oberster SA-Führer (Supreme SA-Leader) SA-Oberführer (SA-Senior Leader) SA-Führer (SA-Leader) SA-Mann (SA-Trooper) In 1923, the SA was disbanded after the failed Munich Beer Hall Putsch. The group was refounded two years later in 1925. Early SA rank insignia (1924–1929) From 1923 to 1925, the SA did not officially exist since Adolf Hitler had been imprisoned for his actions in the Munich Putsch and the Nazi Party banned in Germany. Underground cells of SA men did continue to meet in secret, including one run by an SA leader named Gerhard Roßbach. It was Roßbach who effectively invented the "Nazi brownshirt" uniform
