Naval Commando Flotilla The Naval Commandos began operating before the establishment of the State of Israel, as a naval strike force in the Palyam (Sea Company). Towards the end of 1949, the two commando forces were unified to create the naval commando fleet. Up to 1959, the year in which the commandos were not permitted to wear a distinctive unit badge, the existence of their unit was not publicized. Even today, naval commando methods of operation and organization are kept under a cloak of secrecy. Two guiding principles govern naval commando doctrine: 1. Every defense system is vulnerable. 2. The enemy can deal with weapons and operational methods that are known; for that reason, naval commandos use imagination, daring and initiative, to create situations which cannot be anticipated.
