Södertörn Marine Regiment

Södertörn Marine Regiment (Södertörns marinregemente, designation SMR, was a Swedish Navy coastal artillery unit which operated from 1956 to 2000. The unit was based on Järflotta south of Nynäshamn.

History
Södertörn Marine Regiment was raised in 1956 as the 3rd Coastal Artillery Brigade (Tredje kustartilleribrigaden, KAB 3). The brigade was then in the peace organization under the Vaxholm Coastal Artillery Regiment (KA 1), but was an independent unit in the war organization. The brigade consisted initially in the war organization of a staff at Järflotta and three barrier battalions (spärrbataljoner), Ornö, Mellsten and Askö. On 1 July 1994, the brigade was also separated from the regiment in the peace organization and reorganized into the Södertörn Marine Brigade (Södertörns marinbrigad, SMB).

The Södertörn Group (Södertörnsgruppen) was raised on 1 July 1994 as the Södertörn Marine Brigade (SMB), along with Roslagen Marine Brigade (RMB), and as a result of that the East Coast Naval Command (MKO) was formed in 1990. This as a continuation of the integration of marine units on the lower level, including the coastal artillery brigades reorganized into marine brigades. With this, among other things, the Swedish Navy's base units and the coastal artillery's brigade service units were merged, and came to be part of the marine brigades.

On 1 January 1998, the war organization within the coastal artillery was reduced, whereby Södertörn Marine Brigade was reduced to a regiment, and got the new name Södertörn Marine Regiment (Södertörns marinregemente, SMR). The regiment was disbanded on 30 June 2000 in connection with the Defence Act of 2000.

Heritage
On 1 July 2000, the Södertörn Group (Södertörnsgruppen) was raised, consisting of two battalions, Södertörn Home Guard Battalion and Roslagen Home Guard Battalion. Södertörn Home Guard Battalion was the traditional keeper of the Södertörn Marine Brigade. In 2017 (or 2018), the traditions were transferred to the Södertörn Group, this after the decision that the Home Guard battalions should bear the insignia of the 1st Marine Regiment (Amf 1) as a unit insignia. The regiment's march was inherited by the Södertörn Group, which also took over the heraldic weapon, with the difference that the weapon was laid over two crossed swords.
