Members of the 12th (Airborne) Battalion of the Devonshire Regiment met at the Keep Military Museum in Dorchester for the "final" time.
The Old Veterans Association, known as the Swedebashers, disbanded officially in 2012 after forming in 1945.
Chris Copson, curator of the museum, said the meeting was "poignant" as only about 10 veterans are still alive.
During World War Two the battalion flew into battle using gliders across northern France.
Katrina Thompson's father, General Paul Gleadell, was the driving force behind the association.
She said she believed this would be the final meeting.
"It will get to the stage where there aren't any veterans left, but it is being kept alive in their memory by the sons and daughters.
"It is the end of an era."
Mr Copson said: "The Swedebashers were a remarkable unit by any standards.
"It is the final chapter of an amazing story of what they did during the Second World War."
He said the Swedebasher name came from rural stereotypes about Devon, which was then adopted affectionately by the battalion.
In 1958 the Devonshire Regiment merged with the Dorset Regiment.
It became part of The Rifles in 2007.

Dick's Sporting Goods plunged 23% after sportswear retailer's sales and profits in the second quarter came in below expectations.

Johnstone's first came at the end of a half in which Trinity had thrown away a 12-0 lead and stopped Salford going in level at the break.
He scored again before the visitors reduced the arrears through Justin Carney's try.
However a third score to add to Reece Lyne's effort ended Red Devils hopes.
Since losing in front of Chester at Hull, Trinity have found form to beat Huddersfield, Leeds and now Salford, who were in action for the first time since crowd violence marred their victory at Huddersfield.
Jacob Miller and Michael Sio crossed for Wakefield on the back of cheap possession early on but Salford, prompted by Michael Dobson, fought their way back through Gareth O'Brien and Matt Sarsfield tries.
However winger Johnstone's score before the break was a blow from which the Red Devils never quite recovered, and the loss of Carney to an ankle injury was salt in the wound.
The Wildcats have now achieved more Super League wins this season than they managed in 23 games last year.
