3rd Infantry Battalion (Ireland) The 3rd Infantry Battalion (3 Inf Bn) is a unit of the Irish Army infantry corps. The battalion traces its history back to 1923, when the garrisons of several towns in the north-west of Ireland (the province of Ulster) were ordered to amalgamate and form the 3rd Infantry Battalion. The 3rd Battalion was one of five Battalions in the army at the start of the Emergency, when it was moved into the newly formed 5th Brigade, along with the 16th and 25th Infantry Battalions. During the Emergency it was responsible for defending the southeast of the country from possible invasion and regularly carried out training exercises.
