History

The SA (Sturmabteilung, storm detachment) was established in 1921 as a paramilitary protection squad of the NSDAP. The members of the SA were tasked with protecting party leaders at political rallies and meetings from the paramilitary forces of the opposing political factions. The SA was first utilised on November 4, 1921 at a meeting held in Munich’s "Hofbräuhaus" beer hall. The organisation was banned after the failed putsch in 1923 and was reactivated in February 1925.

Marine-SA trade insignia either took the form of circular patches that were worn on the lower left sleeve or oval patches worn on the upper right sleeve.

There are two Marine-SA Signals insignia. Both are dark blue, with two crosses signal flags in red and white as the regular insignia, and with a red downward pointing bolt of lightning for those that passed the radioman test. The latter was changed to a silver bolt of lightning in 1939.
