4th Marine Regiment (Sweden)

Prior to the Defence Act of 2000, the Swedish government's starting point was that only two units were needed to meet the Swedish Armed Forces' future training of coastal artillery units. One unit was intended to be the main unit for the service branch. Prior to the Defence Act, there were four coastal artillery regiments, Vaxholm Coastal Artillery Regiment and the 1st Coastal Artillery Brigade (KA 1) in Vaxholm, Karlskrona Coastal Artillery Regiment and the 2nd Coastal Artillery Brigade (KA 2) in Karlskrona, Gotland Coastal Artillery Regiment (KA 3) on Gotland and Älvsborg Coastal Artillery Regiment (KA 4) in Gothenburg. The government considered that the coastal artillery regiment in Vaxholm would constitute the main unit of the Swedish Armed Forces' basic organization. As Vaxholm had an existing infrastructure close to the Stockholm archipelago with training areas, which was considered well-dimensioned for the terrain types the unit is expected to operate in. Further arguments for retaining Vaxholm were to maintain coordination with other marine units in the Stockholm area. The government also found that the other coastal artillery regiments lacked the prerequisites to form the main unit for the coastal artillery. The question of what the other unit that would remain as a support unit for Vaxholm was between the coastal artillery regiments in Karlskrona and Gothenburg. In the overall assessment, it was considered that greater investments in both Gothenburg and Karlskrona would be required, as they both lacked the type of training areas that Vaxholm had. On the other hand, both were considered suitable as a support unit for Vaxholm. The government's choice was Gothenburg. Among other things, with the argument that Gothenburg as Sweden's second biggest city needed a military presence. Also the central location in Western Sweden, seen from a conscription travel perspective, contributed to the coastal artillery regiment in Gothenburg. The coastal artillery regiment on Gotland was never relevant to either a main unit or a support unit. As a result, Vaxholm Coastal Artillery Regiment and the 1st Coastal Artillery Brigade (KA 1) in Vaxholm and Älvsborg Coastal Artillery Regiment (KA 4) in Gothenburg remained in the basic organization while Karlskrona Coastal Artillery Regiment and the 2nd Coastal Artillery Brigade (KA 2) in Karlskrona and Gotland Coastal Artillery Regiment (KA 3) on Gotland were disbanded. Hence, the government proposed to the Riksdag that the regiment should be disbanded. However, in the future it was considered important to continue to train units that could perform and operate on the Swedish West Coast. This meant that the installation at Känsö would be maintained, and constitute a detachment to the 1st Marine Regiment. Initially, the regiment will consist of almost 600 employees plus 300 conscripts, which means that it will be organizationally larger than the 1st Marine Regiment (Amf 1) right from the start. This is done by taking over the 17th Patrol Boat Company and the 132nd Naval Security Company, which already existed in Gothenburg. In addition, the 5th Amphibious Battalion is established. In the long term, Amf 4 will consist of approximately 900 employees and 300 conscripts. == Units ==
