Flags have been raised throughout the country in the run-up to Armed Forces Day.
Glasgow's Lord Provost Bob Winter led celebrations in George Square on Monday.
Two special flags were raised in the square in the ceremony to honour Britain's armed forces, past, present and future.
The flag-raising signalled a week of events across the UK to celebrate the role the armed forces play in "preserving a free and safe society".
The flags were specially designed and are based on the Union Flag.
Simultaneously, Armed Forces Day Flags were raised in towns and cities throughout Britain in advance of Armed Forces Day on June 27.
Lord Provost Winter, who was presented with his Veterans' Lapel Badge by the former Secretary of State for Defence Des Browne in 2008, said: "Our armed forces deserve our recognition because of their service, bravery and outstanding contribution to society.
"It is important that veterans and our serving and future military personnel know that Glasgow and the whole of Britain supports them. We owe them a huge debt for the freedom and democracy we enjoy."
The celebrations on June 27 will involve a parade in George Square led by veterans and veterans associations.
They will be followed by serving military who will march with the band of the Royal Regiment of Scotland.
In Edinburgh the flag was hoisted at the city chambers and will fly throughout the week until Saturday.
Lord Provost George Grubb said: "Our armed forces, both serving personnel and veterans, need our continued support and gratitude for the risks they take to keep us safe. Sending people to war is a huge responsibility and remembering them when they return is just as important."
