The Duke of York has attended the last service of remembrance by the Royal Irish Regiment before it disbands its home service battalions.
The Queen attended an RIR march last month
As colonel-in-chief, he joined soldiers at St Anne's Cathedral in Belfast.
The regiment's colours will now remain on permanent display at the cathedral.
Those of the 3rd Battalion and 4th Battalion will be laid up in Armagh and Enniskillen later in the month.
The three RIR home service battalions will be disbanded next July.
More than 60,000 men and women have served in the RIR or UDR since 1970.
The Queen awarded the Royal Irish Regiment the Conspicuous Gallantry Cross at a ceremony in Belfast last month.
Speaking at St Anne's Cathedral on Sunday, Lieutenant Colonel Chris Kemp, commanding officer of the 2nd Battalion, said it was a great honour to have Prince Andrew at the event.
"Today is the last time all the home service battalions of the Royal Irish Regiment will be represented at our annual Remembrance Day service before being disbanded in 2007," he said.
"It is also the last time the Colours of all three home service battalions will be seen in public together," he said.
"The traditions of the Royal Irish Regiment live on as the
bravery and sacrifice of our brothers-in-arms in the 1st Battalion, the Royal Irish Regiment showed recently in Afghanistan."
