Former personnel say they have met "resistance" from their local council (Picture: SWNS).
Army veterans have expressed their outrage after councillors denied their request to mark Remembrance Day with a traditional 11am silence and parade.
The 100th anniversary of the first two-minute silence will take place all over the UK at 11am on Armistice Day, 11 November.
But Ammanford Town Council rejected a plea to hold an 11am parade, service and silence in the Welsh town.
Councillors ruled the parade has to take place three hours later than the rest of the UK - missing the significant 11am national commemoration.
The parade in the town has been held at 2pm since the 1950s, to allow workers from the nearby coal mines to attend the service.
However, the pits closed in the 1980s, and some members of the Ammanford branch of the Royal British Legion have begged the council to shelf the "outdated" tradition.
Some locals have branded the decision as "absolutely sickening and disgraceful", with some set to boycott the parade.
Peter Reed, ex-Army Sergeant Major and British Legion member, said: "We've been hit with a brick wall.
"The council has closed ranks.
"The veterans of Ammanford have been trying to get the remembrance parade at 11am for three years now and this year being the 100th year we thought we had done it.
"We have met resistance from the council who won’t be bullied by - as they call us - 'a bunch of service people'."
He added: "The local vets, who have served a great deal, are very disgusted with the local council and the way they treat us."
The two-minute silence takes place at 11am to represent the guns of Europe going silent on the eleventh hour, of the eleventh day, of the eleventh month.
The silent tribute is observed across the nation at war memorials, military cemeteries and other public spaces.
The Ammanford commemorations are organised by the town's Royal British Legion branch on behalf of the council and start with a wreath memorial followed by a parade by scouts, air cadets and bands and a church service.
On Monday, councillors held a meeting to discuss and vote on the issue, but only two out of fourteen voted in favour of the change.
It comes after an apparent split in the Ammanford branch of the Royal British Legion - with some asking for an 11am switch and others urging the councillors to stick with 2pm.
Simon Carter, landlord of the Great Western Hotel in Ammanford, said: "I am totally disgusted that the timing is still set at 2pm.
"It certainly makes sense to fall into line with the rest of the United Kingdom but with Ammanford, it springs to mind that some people are afraid of change or just too stubborn and like to be King of the Castle.
"Remembrance Sunday is all about those that have given their lives so that we can enjoy our lives and live freely as we do."
Councillor Jonathan Davies, Mayor of Ammanford, confirmed that he and councillor Julia Rees voted to change the time to 11am, but were overruled.
An official spokesperson for the Ammanford Royal British Legion Branch said the branch had sent a letter to the council recommending the council keep the timings at 2pm, because cadets and scouts attended the parade at 5pm.
