Sturmabteilung

The '''''' (; or loosely 'stormtroopers'), or SA, was the original paramilitary organisation under Adolf Hitler and the Nazi Party of Germany. It played a significant role in Hitler's rise to power in the 1920s and early 1930s. Its primary purposes were providing protection for Nazi rallies and assemblies, disrupting the meetings of opposing parties, fighting against the paramilitary units of the opposing parties, especially the Roter Frontkämpferbund of the Communist Party of Germany (KPD) and the Reichsbanner Schwarz-Rot-Gold of the Social Democratic Party of Germany (SPD), and intimidating Romani, trade unionists, and especially Jews.

The SA were colloquially called Brownshirts () because of the colour of their uniform's shirts, similar to Benito Mussolini's Blackshirts. The official SA uniform was a brown shirt with a brown tie. The colour came about because a large shipment of Lettow-shirts, originally intended for the German colonial troops in Germany's former East Africa colony but which never reached its destination because of naval blockades, was purchased in 1921 by Gerhard Roßbach for use by his Freikorps paramilitary unit. They were later used for his organization in Salzburg, and in 1924 were adopted by the Schill Youth in Germany. The "Schill Sportversand" then became the main supplier for the SA's brown shirts. The SA developed pseudo-military titles for its members, with ranks that were later adopted by several other Nazi Party groups.
