BeVo WWII Kriegsmarine coastal artillery breast eagle insignia black background.
Kriegsmarine naval artillery and anti-aircraft crews were considered as shore personnel and assigned to either the Marine-Artillerie-Einheiten (for naval artillery) or Marine-Flak-Einheiten (naval anti-aircraft). Artillery units were organized into either regiments or sections while flak units were maintained in brigades and regiments. Both types of units were assigned to various ports and harbors and thus were under the direct operational authority of both the port commanders as well as the commander harbor security forces. During actual invasion of coastal regions by enemy forces, these units became part of the sea defense zones.
