As you will see here the Army and the Royal Marines have almost identical ranks however minor changes.
These are the general duties Royal Marines Commandos who fight at section level
Lance Corporals are section 2 i/c and assist Corporals in leading the section
These are section commanders which make decisions in a firefight
Normally Sgt's are troop Sgt's and assist young officers in decision making.
Colour Sergeants are the link between officers and their men, colour Sgts are close with both men and officers.
Warrent officer 2
Normally heads of departments or CSM
Warrent Officer 1
All Royal Marine Officers hold the rank of 2nd Lieutenant from the first day of Phase 1 Training.
2nd Lt’s hold this rank until they have completed Phase 1 Training at CTCRM and Phase 2 Training as a Troop Commander in an operational unit.
Senior Corps Commissioned Officers hold the rank of Lieutenant whilst undergoing training at CTCRM.
In Commando units a Lt could still be a Troop Commander because the rank is also held by Direct Entry Officers who commence training before the age of 21.
The natural progression of promotion to Captain allows for a greater role in the decision making progress and command abilities.
With promotion to the rank of Captain comes the possibility of specialisation within the Royal Marines. These specialisations include Mountain Leaders, Heavy Weapons or Signals.
Promotion to Captain can lead to any of the following appointments and responsibilities:
• Second-in-Command (2ic) of a sub-unit of approximately 120 soldiers.
• Adjutant: Normally a senior Captain whose primary role is to assist the Commanding Officer of a Commando unit. Such an individual would have been selected because of his outstanding ability. A ‘successful’ Adjutant would probably go on to greater things.
• Staff Officer Grade 3 (SO3) in a military headquarters – probably at Brigade level.
• Greater participation in the decision making process with tactical responsibility for ground operations.
Promotion to Major is a big leap on the promotion ‘ladder’ and denotes an Officer of mid-level command status.
Promotion to Major can lead to any of the following appointments:
• Command of a minor or sub-unit of approximately 120 Officers and Marines. As the Officer Commanding (OC) of such a unit comes responsibility for the management, training, discipline and welfare of the personnel placed under his command.
• Staff Officer Grade 2 (SO2) in a military headquarters – probably at Division level.
• Chief of Staff (COS) in a Brigade Headquarters. This key appointment is more often than not filled by Majors who have excelled when attending the Intermediate Staff and Command Course. The COS is the principal Staff Officer in the Headquarters who works closely with the Commander (a Brigadier) and whose duties are many and various!
With promotion to Lt Col comes the possible ambition of any professional Officer in the Royal Marines – the command of a Commando or similar sole command appointment within The Corps.
Command of a major unit is the pinnacle of the chosen Commanding Officer’s (CO) career with the tenure of command lasting approximately two years. With this opportunity to command comes the responsibility for upwards of 650 Officers and Marines as well as the operational effectiveness of the Commando when considering military capability, management of resources, discipline, training and welfare of those under command.
