Royal Marine Cadets

Who we are

The Royal Marines Cadets are under the over all command of the Unit Commanding Officer and their training and activities are directed by the Unit Detachment Commander. The Royal Marines Cadets and Blue Jacket (Sea Cadets) all form part of the Sea Cadet Corps and operate as a Ships Company; as such training is often combined within the unit.

There are a number of activities that make up the corps syllabus for Royal Marines Cadet (RMC) Training, these are, Field Craft, Section attacks and defence, Camouflage and Concealment, RM Corps History, Map Reading and Land Navigation and Weapon handling and Marksmanship. In addition to these it is encouraged that RMCs participate as any other cadet in all other Sea cadet courses, proficiencies, and specialisations.

Each year every detachment in the Sea Cadet Corps is assessed in the field by the Staff Royal Marines Officer (SMRO). The SMRO is a serving Royal Marine Colour Sergeant who is based at Sea cadet HQ London. He reports directly to the Captain of the Sea cadets. The Royal Marines Cadet training is physically demanding and require a good level of physical and mental fitness to complete. As you can imagine the training in through and requires regular attendance.

The unit operates a waiting list to join the Royal Marines Cadet Detachment and firstly any New Entry will have to participate in combined initial training in the Sea Cadet Corps. Cadets applying to become Royal Marines Cadets will be held on a waiting list and selection to become a Royal Marines Cadet will be made by the Commanding Officer based on advise from other senior members of staff. The cadets will be selected based on enthusiasm, attendance and physical ability for the training.
