Training As with the army and air force, all officers of the navy are trained and commissioned at the Officer Cadet School with their interservice counterparts. As midshipmen, part of their training involves being deployed four weeks at sea with the regular fleet to hone their skills in leadership, navigation and basic seamanship. Navy officers are also offered specialization courses later in their careers at the Naval Officers' Advanced Schools(NAS) which is part of the SAF Advanced School(SAS). The courses offered are Naval Advanced Officer Course (NAOC), Mine Hunting Officer Course (MHOC), Naval Warfare Officer Course (NWOC) and Command Preparatory Programme (CPP). Enlisted specialists and regular military experts (ratings) are instructed in their specialized domains at the Naval Military Experts Institute, under the Maritime Training and Doctrine Command (MTDC), based at Changi Naval Base. This training consists of all the key aspects of the duties the sailors are expected to perform on board the ships. This includes basic firefighting and damage control skills, rope handling and seamanship skills as well as shiphandling which is done through a ship simulator allowing trainees to practice their watchkeeping skills inside a safe, controlled environment. The enlisted specialists and military experts undergo a rigorous and realistic Summative Exercise (SUMEX)
