Events took place in cities and towns across the county, as people turned out to honour those who have died in service, and thank serving members of the armed forces.
A large parade in Leeds involved hundreds of people meeting in Victoria Gardens outside Leeds Art Gallery and Town Hall in The Headrow from 11am.
A spokesman for the organisers said: “This year’s Armed Forces Day is set to be another spectacular event; with a host of events and activities on Victoria Gardens (outside the Art Gallery and Town Hall) and Cookridge Street.
“Hosted by the Lord Mayor of Leeds, it is part of a national day celebrating the courage and contribution of the United Kingdom’s Armed Forces past and present.”
One of the highlights was the parade through the city centre, featuring service men and women, past and present, alongside cadets from across the city.
There was be a variety of displays, military vehicles and military-related stalls, with family-friendly activities including a climbing wall, Breeze Boot Camp and fun, themed crafts.
There was a chance to meet veterans of all ages, browse a selection of stalls and enjoy a range of performances on a specially constructed stage on Cookridge Street. A Drum Head Service was due to take place on Leeds City Art Gallery steps; and the climax of the day will be a flyover by a Lancaster Bomber (weather permitting) which will take place over the city centre.
