A major parade is to be held today, mark the disbandment of the Royal Irish Regiment's home service battalions. Several thousand members of the regiment, and its predecessor the UDR, will attend the ceremony at Balmoral Showgrounds in Belfast. The three home service battalions of the Royal Irish Regiment will be disbanded next July. More than 60,000 men and women have served in the Royal Irish Regiment or the UDR since 1970. Some 300 home service soldiers drawn from the Holywood-based 2nd Battalion, the Armagh-based 3rd Battalion, and the Omagh-based 4th Battalion will parade at the showgrounds. They will be accompanied by musicians from the band of The Royal Irish Regiment and 100 former UDR soldiers of the Regimental Association.
