Those who were eligible to join O.N.E. at the time included ex-servicemen, provided they had been honourably discharged, from: The Defence Forces (Óglaigh na hÉireann), 1916 men, pre-Truce IRA, the National Army, the Volunteer Force (including members of the 26th Battalion), the Marine Service, and serving members of the Reserve. Membership of the latter was suspended when called for training or active service. At that time the Air Corps was considered part of the Army. It later became a separate service within the Defence Forces and the Marine Service evolved into the Naval Service. Today, ONE is a veterans organisation, a registered charity for all veterans of the Defence Forces, a company limited by guarantee (CLG), and an approved housing body (AHB). Its primary objective is to support the needs of Irish veterans by the provision of accommodation to homeless veterans in its Veterans’ Hostels and the provision of other advice and support to veterans through its nationwide network of Branches and Veterans’ Support Centres. ONE’s services are available to all veterans, the women and men of the Defence Forces and we also facilitate homeless veterans from other countries living in Ireland from time to time. ONE currently provides accommodation (board and lodging) for approximately 51 veterans, who otherwise would be homeless, in its three residential homes in Cobh, Athlone, Dublin and Letterkenny. ONE has created a nationwide network of 15 Veteran’s Support Centres based around its 38 Branches. In October 2021, ONE developed and opened a 5-bedroom hostel in Cobh to address the increasing challenge of homelessness among veterans and this will be followed by a 6-bedroom facility in Cork City leading to the availability of 57 single rooms for homeless veterans.
