individual unit consists of a Royal Naval Reserve Lieutenant as the unit's Senior Training Officer (STO) and a number of Training Officers (TOs), who vary between Royal Naval Reserve Acting Sub-Lieutenants, Sub-Lieutenants and Lieutenants. This format, with the exception of rank, roughly mirrors the training staff and format of BRNC. URNU training officers now wear the reserves' 'R' inside their executive curl to show their status as honorary officers. Some are being given the opportunity to attend AIBs and pass out of the reserve's Accelerated Officer Programme. Officer Cadets Undergraduates usually join for 3 years, with options to extend this membership to 4 or 5 years, providing they can sufficiantly convince their Commanding Officer thet their continued membership would be of value to the unit. Members are list 7B reservists and therefore there is no call-up liability and members may leave at any time. Each URNU comprises 51 students, who usually join for the duration of their degree, with the option of taking a year out or leaving at any time. The URNU's also have attached cadets that are on Navy sponsorship/cadetship programs. Ranks During their first year, URNU students wear URNU tabs on their shoulders and are Acting Officer Cadets (A/OC). On completion of their first year they receive a white officer cadet tab in addition to the URNU slide and are referred to as substantive Officer Cadets (OC). On completion of their second year students will wear Midshipman rank slides in addition to URNU tabs and are referred to as Acting Midshipmen (A/Mid). URNU OCs work through training logs and receive training credits (formerly task books) but these no longer correspond to the URNU ranks, which are promoted based on a minimum time spent attending training per year. To achieve the substansive rank of Midshipman the URNU OC must pass out of BRNC via the reserve or regular courses. Committee Each URNU has a senior midshipman (SMid) and deputy senior midshipman (DSMid) (known as the Vice-President or 'VP' in URNU Glasgow due to their role as mess vice-president) supported by a committee, made up of various roles, which differ according to unit but will generally include a treasurer and sports and adventurous training officers alongside other roles. This committee will take a leading role in programme planning and assist in the running of the unit. Training and unit life Training focuses on leadership, navigation and seamanship, and this
