The right to wear the green beret does not come easily and is one that has to be earned by completion of the most demanding training course in the British Armed Forces.

This 'no compromise' approach reflects the corps' fierce pride and is important in maintaining its standards and commitment to excellence.

The essential qualities which are required of a Royal Marines Commando include fitness, commitment, discipline and self-confidence. Some of this can be instilled during the training programme, but fitness, initiative and determination must be displayed from the start.
