The Royal Marines are the world's most elite amphibious force.
There are two distinct tiers, commissioned officers and other ranks.
The term 'officer' refers to someone with a commission, which is a formal document of appointment signed by the monarch.
To distinguish Royal Marines from their Army colleagues, their names are followed by the words 'Royal Marines' or 'RM'.
All Royal Marines Officers, recruits and reserves are trained at the Commando Training Centre, (CTCRM), at Lympstone in Devon.
