The contribution paid by the Armed Forces was recognised on Sunday.
Residents lined Douglas seafront to show their respect as the Armed Forces Day parade took place.
It saw 150 veterans and 40 serving personnel – including seven Marines and eight members from submarine HMS Vigilant – march along the seafront led by bands and joined by primary and secondary school students.
Lieutenant Governor Adam Wood took the salute, accompanied by Douglas Mayor Stan Cain and Second World War veteran and Manxman Major-General Sir Peter Downward.
By his retirement from the active list in 1979, he had been awarded both the Distinguished Service Order and Distinguished Flying Cross.
The event had greater significance this year as the island marks the centenary of the outbreak of World War One and the 70th anniversary of D-Day.
The church service inside the Villa Marina was led by Archdeacon of Man Andrew Brown. It stopped several times for those attending to remember those in the First World War.
Brigadier Norman Butler, chairman of the Armed Forces Day committee, described the event as a ‘great success’.
