The role at a glance

What you’ll do

Can you lead the leaders? The Royal Marines are the world’s most elite amphibious force. And if you’re a Royal Marines Commando Officer you’ll be in charge of the best. Your determination will know no bounds, just like your ability to get the most out of your team. As you tackle some of our most challenging operations, you’ll encounter everything from the hottest deserts, to the freezing Arctic. And to get the job done, you’ll need that something special that sets you apart: your state of mind.

Your role

  • Lead deployments to wherever your team is needed, from humanitarian aid and peacekeeping missions in the Middle East, to responding to global conflicts in some of the most hostile environments imaginable.
  • Operate from Royal Navy ships and aircraft, using state of the art weapons as you deploy to conflict zones all over the world. You might be neutralising a terrorist threat in North Africa one day, and supporting domestic forces in the Middle East the next.
  • Embody the Royal Marines ethos. That means combining the Commando values (excellence, integrity, self-discipline and humility), the Commando qualities (courage, determination, unselfishness and cheerfulness), with the Commando mindset: “Be the first to understand; the first to adapt and respond; and the first to overcome.”
  • The people you lead will be exceptional soldiers, who are prepared to go wherever you ask them. To command their respect, you’ll need to show that you can do whatever you ask of them. That’s why you’ll complete the same Commando course, and play a hands-on role in every operation.

Starting your career

Joining process

Once you’ve confirmed your eligibility and registered your interest, the joining process is as follows:

  • Submit your application

  • Pass the Defence Aptitude Assessment (DAA) which is normally conducted using your own device over the Shine video platform

  • Take the medical and eye tests

  • Pass the Pre-Joining Fitness Test Plus (PJFT+)

  • Attend the Admiralty Interview Board (AIB)

    This stage is unique to officers and takes place in two parts. A Pre Recorded Interview (PRI) is an online assessment which assesses your motivation to join the Royal Navy as an officer and your awareness of the Royal Navy. The Group Planning Exercise (GPE) is the second stage of the AIB and is an online competency based assessment which will take place on a separate day to the PRI. It will be conducted in a virtual group environment and you will be assessed on your contribution to the team based on your individual performance

  • Complete the Royal Marines Officer Selection Course (OSC)

Initial Training

Once you've passed the recruiting process and been selected by the Final Selection Board (FSB), you'll be given a date to start Initial Training at Commando Training Centre Royal Marines (CTCRM), Lympstone. You'll spend 16 months here, learning all the skills you need to become an elite amphibious soldier.

You will join with a group of fellow Young Officer Recruits, known as a batch. You'll stay with your batch throughout your time at CTCRM, finishing your training and earning your green beret together. You'll also develop the advanced tactical skills and leadership qualities you’ll need to motivate, train and inspire Royal Marines Commandos in camp, on exercise, and in the field.

You will take part in regular exercises, including a three-week deployment to the USA towards the end of the course. You'll also need to pass the same Commando Course as other ranks, which includes four tests: an endurance course, a nine-mile speed march, a Tarzan assault course, and a 30-mile march. The only difference is that you'll have to complete these tests in a shorter time than other ranks recruits.

There is also a swimming test, so if you can't swim, make sure you learn by the time you join us.

Professional training

You will complete your Officer Training with Advanced Military Management Training and Unit Management, Exercise Planning and Final Exercise phases. These will give you the strategic, decision-making, management and leadership skills that you'll call upon every day. 

Your personal development will continue throughout your career in the Royal Marines, with regular opportunities to gain specialist skills and further enhance your leadership abilities.
