Slave forts were established all along the coast of West Africa, to house captured Africans in holding pens (barracoons) awaiting transport. They were equipped with up to a hundred guns and cannons to defend European interests on the coast, by keeping competitors at bay. There were approximately 80 castles dotted along the slave-trading coast.
They also serve as monitors for, and advocates of, the enlisted men in the command. This position exists in all units of battalion size and larger. A Garrison (or Post) CSM is the senior CSM on the installation (by position - if not by date of rank, anyway). He will serve as the liaison for other unit's CSM's and the NCO support channel to the Garrison Commander from tenant units on the post. Keep soldiers off the grass.
