Captain Sir Tom Moore said it is "truly a great honour" to be made honorary colonel of an Army training college as he visited the military establishment aspart of his new role.
The 100-year-old Second World War veteran told junior soldiers to take full advantage of the "outstanding" Army Foundation College in Yorkshire, as he was shown around the facility today (3rd August).
Captain Sir Tom raised almost #33 million for the NHS by walking 100 laps of his garden in the village of Marston Moretaine in Bedfordshire before he turned 100 in April.
He was appointed honorary colonel for the college to mark his milestone birthday.During his visit to the college on Monday, he said he was "absolutely speechless" to be made honorary colonel.
To go up in so many ranks so quickly, I'm really delighted with that and I know it's only an honorary one but really I'm absolutely thrilled with the fact that the honour has been placed on me. It really is truly a great honour.
Captain Sir Tom described the college as a "marvellous place" and said he did not know whether he would have been capable of going through the training.
"I never anticipated some time ago that I would get the opportunity or the privilege of coming here and I never knew that it's such an outstanding operation," he said.
Captain Sir Tom said he would advise the junior soldiers at the college to try to be the best.
When I was conscripted, one of the things I did when I joined the Army, I looked round to see all the other people and thought 'I'm going to be the best'. Without climbing over anyone's shoulders, just quietly get on and do your best and be your best.
He arrived at the college site in a people carrier, escorted by military police, and posed for a photograph with staff from all departments before attending a service in the chapel.
He waved and gave a thumbs up to assembled junior soldiers, who gave him a round of applause as he walked towards them from his vehicle.
As the audience were asked for questions, a member of civilian staff said: "We just want to say a big thank you from everyone for the inspiration."
Captain Sir Tom replied: "It has been my pleasure."
Before he left the site, he was presented with a commemorative frame containing photos of the college and his visit and badges of the Duke of Wellington's Regiment, in which he served, and the Army Foundation College.
He had earlier been given a colonel's rank slide, which he wore on his tie during the visit.
He was knighted by the Queen during a unique open-air ceremony at Windsor Castle earlier in July and said the knighthood was "something very special".
