Ex-servicemen and women gathered on Monday to pay tribute to those who served at the School of Artillery in Manorbier.
The close ties that the school enjoyed with Tenby led to it erecting a gated archway at the entrance to the town's war memorial, following its closure in 1970.
The gates, regimental badges and inscription plaques were replaced last year in a joint project by Pembrokeshire County Council to mark the start of the First World War.
"When we heard about the refurbishment, we felt we should have a get-together in recognition of the many who trained at Manorbier," said Marianne Hooker, of the Marches and Mid Wales branch of the WRACA (Women's Royal Army Corps Association).
"The South Pembs branch of the Royal Artillery Association were so helpful and took it on board immediately."
WRACA represents all the women who served with either the WRAC or the ATS (Auxiliary Territorial Service) between 1919 and 1992, and has around 3,000 members worldwide aged from 47 to 102.
Its national vice-president, Colonel Ali Brown (retired), was among those who travelled to Tenby.
One member who made the journey from Worcester was 63-year-old Marg Davies, originally from Pembroke Dock, who was assistant adjutant of 12 Light Air Defence Regiment.
"I was actually at Manorbier for the last firing of the Bofors gun, so when I heard that the war memorial gates had been restored, I had to be here," she said.
The ladies were welcomed by local RAA chairman Chris Roberts and members, and entertained to dinner at the branch's monthly meeting.
