but the ship's computer system did not indicate anything wrong, so after three rounds were fired the FO officer dismissed the ship from the firing line. The ship's weapons staff spent the next 24 hours going through their system, and discovered their radar had not locked onto the correct datum point, creating an error in firing equal to that calculated by the FO officer. The Argentine military command were very quick to announce this error as a deliberate act of aggression towards the Islanders. The FO team, which was still conducting covert reconnaissance and bombardment, learned of the tragedy from the BBC World Service. FO teams called artillery fire and air strikes onto Argentine positions in support of every major British assault. With the Argentine surrender, the unit returned to their home in Poole. Persian Gulf 1991 148 provided teams initially in Northern Iraq and later assisted in the Scud missile hunt. Balkan Wars 148 provided fire support to various British formations. Iraq 3 Commando Brigade conducted an amphibious landing to occupy the Al Faw Peninsula during Operation Telic, the 2003 invasion of Iraq. On the first night of the operation the unit suffered its first deaths of the war when a US Marine helicopter crashed close to the Iraq Border. Afghanistan Lance Bombardier Ross Clark aged 25 from South Africa, and Lance Bombardier Liam McLaughlin, aged 21 from Lancashire, were killed during a rocket attack in the Sangin area of Helmand province on 3 March 2007. Battery structure The battery is formed into a number of Fire Support Teams (FSTs), operating ashore or in advance of the Forward Edge of Battle Area, to observe and identify candidate targets, conduct preliminary Battle Damage Assessment, adjust fire or provide target illumination for laser guided weapons. The battery consists of HQ personnel, Fire Support Teams and administrative and logistical support personnel. A FST consists of five personnel; a patrol commander (a Captain Royal Artillery), with a Bombardier RA as the second in command (2IC). The rest of the team consists of a (Royal Navy) communicator, RA Lance Bombardier, and Gunner. The team can be split in two with the Bombardier commanding one team and the Captain the other. All unit members are capable of co-ordinating air strikes and directing artillery fire. Selection and introductory training Volunteers for the battery must first complete the All Arms Commando Course, and a basic parachute course.
