The Queen has sympathised with the children caught up in the Manchester bombing, expressing her hopes that the youngsters do not suffer long-term mental health problems.
During the last Buckingham Palace garden party of the year, the Queen discussed the psychological repercussions of the suicide attack with two Transport for London (TfL) staff working with injured ex-servicemen and women who can sometimes suffer from post-traumatic stress disorder (PTSD).
Chad Frankish, 49, a programme manager, and Brendan Sleight, 42, a chief engineer, started a programme at TfL two years ago to get wounded and sick ex-armed forces personnel into employment with the transport company and now have 45 former military on the payroll.
Mr Sleight said of their meeting with the Queen: "We talked about PTSD and whether some of the young children in Manchester will be affected by that, and she mentioned hopefully they won't be affected, they may have been unconscious.
"And we talked about, now it's a recognised condition, especially with the work of her grandchild, that it will be more open and they'll get help for any PTSD straight away. "
The Queen's grandson Prince Harry has been working to support the UK's injured and sick military for a number of years and has been the driving force behind the Paralympic-style Invictus Games for wounded armed forces members and veterans.
With the Duke and Duchess of Cambridge, Harry has also been encouraging the public to speak openly about their mental health problems through the royal trio's Heads Together campaign.
Mr Sleight said of the Queen: "She seemed very informed because she mentioned that PTSD could come back, and we found that with some of the ex-servicemen that it's not just a one-off treatment, we have to give them continued support and build that support network around them."
When the monarch visited Royal Manchester Children's Hospital a few days after the bombing to meet some of the injured young children, she condemned the attack as "wicked".
Prince Harry inspired one of TfL's ex-military staff members Graeme Monk, a former Royal Marine Commando who lost a leg, arm and eye in a blast from an improvised explosive device in Afghanistan, to apply to the company for work.
Mr Sleight said about the prince: "Through the work he's been doing to help build confidence, Graeme had the confidence to come along to one of our industry days and he's ended up working for Transport for London, looking at smart street furniture to prevent the risk of road side bombs."
The former Marine is believed to have met Harry earlier this year when the Prince made a private visit to a treatment centre.
Mr Frankish, a former serviceman who served in the RAF and the Royal Engineers, said about the potential of the ex-military: "This is a whole pool of people we can immediately tap into and with some reasonable adjustments we can set them on path to a fantastic career in the transport sector.
"This is the right thing to do, we should be doing this for our ex-Armed Forces - we should be supporting them, we should be helping them, we should be helping them to find work."
