Marine inquest hears evidence about instructors swearing and shouting

Col Catton said Royal Marine training had undergone a “fundamental shift” in the last two decades.

“We want people to join, and we need these bright young people, and we are very fortunate to attract some of the very best of society,” he said.

“There is a responsibility there to give them the very best instruction.

“If I was to think more broadly about what we do at the Commando Training Centre with that initial entry, what we are really doing is helping them realise their potential.

“Some of that training is very hard and some of the psychology around it is very hard and very uncomfortable.”

The inquest was adjourned until next week.
