 From the late 1980s there were six brigades.Later, all but two coastal artillery brigades were renamed marine brigades ("marinbrigader").Both naval and army units were included, and the personnel varied between 3,000 and 9,000 (In both KAB 1 and KAB 3, there were plenty of army units; KAB 1, for example, had 3 bicycle infantry battalions grouped for tasks at Väddö).
