The DFTC also encompasses Glen of Imaal in County Wicklow, which is the primary artillery and anti-tank firing range for the army.

Today it is an independent unit of the DFTC based at the Curragh that provides training in use and operation of the Mowag Armoured Personnel Carrier.

Highly secretive in nature, the ARW has deployed overseas as part of Irish UN peacekeeping missions.

Responsibilities include counter-terrorism, intelligence gathering, hostage rescue and close protection.

The Army Rangers work with the Directorate of Military Intelligence (G2), the national intelligence service, and trains with the specialist firearms and tactics service of the Garda Síochána (national police), known as the Emergency Response Unit (ERU).
