professional logistics command course (maritime) – PLCC(M) – in September 2010. All training takes place at what was the Royal Naval Supply School (RNSS), since 2004 the Defence Maritime Logistics School (DMLS). The first WRNS officer was appointed to SCC in April 1980 and civilian officers of the RNSTS or Director General Supply and Transport (Navy) civil servants were occasional students, sometimes going to sea for a short familiarization afterwards. Typically, in the 1970s and 1980s, a commando carrier such as would have nine supply officers on board led by a commander (S), including two borne for the duties of captain's secretary – a lieutenant-commander and captain's assistant secretary – a lieutenant or sub-lieutenant. A guided missile destroyer had three supply officers on board, one as captain's secretary, and a Leander-class frigate, survey ship and nuclear submarine just the one supply officer in "supply charge", usually a senior lieutenant (S), with a junior seaman officer given the additional role of "correspondence officer". A frigate squadron leader had a lieutenant-commander as squadron supply officer and a junior lieutenant or sub-lieutenant as captain's secretary. Supply officers rarely served in ships with a ship's company of fewer than 100. some supply branch captains and commodores have been appointed in command of large naval shore establishments such as , , and . In the 1980s, one former submariner supply officer served successfully as first lieutenant (executive officer) of a frigate. From 2004–2007, lieutenant-commander (commander from 2006) Heber Ackland served as equerry to Her Majesty Queen Elizabeth II.

A few supply officers are trained as barristers and one captain (S) serves as Chief Naval Judge Advocate (CNJA). In the Navy List 2006, 26 male and female logistics officers were listed as barristers. Although much of their time can be spent in criminal cases at courts martial, military lawyers are also required in all major operational theatres as legal advisers to the commanding admiral or general. The Navy legal service also covers employment law, liability of public authorities and the drafting of Acts of Parliament. As of 2010, service lawyers could expect to rejoin their original branch of service every few years (e.g. Naval ships, Royal Marine Commandos), to maintain a sense of balance. In 1979 the then CNJA (captain
