Major Tom White, is set to start one of the most important jobs in the Royal household this week. He served with the Royal Marines since 2007 and will now assist members of the Royal Family as an officer.
In March 2009, he helped avoid a massacre at a school in Afghanistan.
The Taliban had planned to set off a bomb sing a device triggered by a pressure plate.
Wires under the building were discovered and the bomb was effectively deactivated.
At the time, Mr White said: “It turns your stomach to think what could have happened if we hadn’t found the bombs.
“These people knew they could have blown a lot of kids sky high – and they didn’t care.
“I have quite a low opinion of someone who would bomb a school. They don’t value young life at all.”
The Times’ Royal Correspondent Roya Nikkhah said Mr White will become the first Royal Marines commando to take up the role.
Prince Harry stepped down from his captain general role in March after he decided to quit his senior royal post.

“We were delighted when Harry was appointed captain general. Him walking away was a huge disappointment.
“The Royal Marines have felt they’ve been handed from pillar to post but this is a proud moment.”
A source who formerly worked with Mr White told the publication: “He is one of the best Royal Marines officers I’ve come across.
