Military personnel working in London during the Olympics will be able to travel for free on all Transport for London (TfL) services this summer.
When in uniform, military personnel will be offered free travel on the Tube, London buses, the Docklands Light Railway and London Overground.
Mayor of London Boris Johnson said: “London is ready to welcome the world and host a hugely successful Olympic and Paralympic Games.
“That success will be in no small measure down to the contribution of our boys and girls in the military.
“Now, as ever, they have shown themselves ready to go above and beyond the call of duty.”
