polish marines there were some references to th coastal defense brigade as the polish marines unfortunately this is not true after disbanding the th coastal defense division in and scrapping most of landing ships there is no amphibious assault unit in the polish army the th coastal defense brigade only bears traditions of the th division and it practices small scale experimental exercises with amphibious assault but it's still not amphibious assault unit at least up to there was no decision of creating a real amphibious assault unit in the polish army
