@Frank Apisa,
Just because this was mentioned a couple of times now:
"Brown shirts" (in German "Sturmabteilung" [
Storm Detachment] was a kind of paramilitary wing of the NSDAP ("Nazi party").
Because of its uniform with brown shirts from 1924 onward, they also called "Brown Shirts" by party members. In the run-up to the seizure of power in 1933, the organisation devoted itself, in addition to propaganda, intensively to street fighting and attacks on social democrats, communists and Jews. Conflicts with state power were carefully avoided.
After SS units had assassinated the SA leadership in the so-called Röhm Putsch in mid-1934, it initially lost much, and later almost all, of its importance in the further period of National Socialism.
