Judging by comments on other threads different regiments had different roles/experiences on the RAC's only resident Northern Ireland tour. So let me tell you about 1 RTR and see how we differed from you? this is from memory so there might be a few small errors. 1 RTR replaced 16/5L in April 1973 and 18 months later (Nov 1974) handed over to 15/19H. We had 3 Sabre sqns, Sqn orbat was 4 car tps each with FSC Mk2 x 4, one tp with FSC x2 and Saladin x2. Assault troop with 2 x FSC and 4 x Saracen APC. We operated a 3 x 3 week cycle, one Sqn in Tyrone, one Sqn in Fermanagh and one sqn off ops in Lisanelly Barracks Omagh. In Tyrone, SHQ was based at Lisanelly, the car troops were based at the out stations each with an assault section attached. Outstations were Castlederg (Rockwood UDR base), RUC Beragh, Clogher (The Deanery) and Newtonstewart ( UDR Greyvale). Greyvale was burnt down when a UDR soldier put petrol on a fire and the troops then patrolled from Lisanelly Barracks. We were based at Pomeroy for a short spell after Greyvale was lost but it was out of our AOR and we were soon withdrawn. One troop plus assault section was always rotated through Lisanelly Barracks for guard and standby duties. In Fermanagh, SHQ was based at St Angelo Camp Ennislkillen. Assault Troop operated as a unit and was always based at RUC Belleek. Car tps were based at Belcoo, Kinawley, Lisnaskea and Rosslea. Again there was rotation through St Angelo for standby duties, and often a car troop would be at Belleek with Assault troop when an assaullt section was at St Angelo In Lisanelly when off ops, half the sqn went on leave, the other half did vehicle maintenance and a stack of guard duties. We covered 53% of the Ulster/Eire border, we were not province reserve or anything like that and apart from some fuel tanker escorts (during the ulster workers strike) I'm pretty sure we were not deployed elswhere. We had an Air (helicopter) Sqn with Sioux and Scout choppers as part of the regiment based at Omagh. 4 troop A Sqn was made up entirely of volunteer soldiers from 4 RTR (RAC Training Regiment Catterick) on 4 month tours. That's a short description of 1 RTR, it will be interesting to hear how things changed over the years till 1982.
