In 2003 the Battery accompanied the Regiment to Iraq where the Regiment fired all 18 guns in the first shots fired by any coalition troops in the ground campaign. The battery then moved into Iraq to secure the Rumaylah oilfields where they were involved in a substantial counter-battery battle with Iraqi artillery units. BK Capt Grant Ingleton was awarded the MC for his actions on the gun position during the counter-battery duel. The Bty then re-rolled into the infantry role to conduct peace support operations in Maysan Province.
