Armed Support Unit

Armed Support Units (ASU) are specialist regional firearms units of the Garda Síochána, the national police force of Ireland. Based in all four Garda regions in the country, Gardaí attached to an ASU unit carry a combination of lethal firearms and non-lethal weapons, as opposed to regular uniformed Gardaí, who are unarmed, and detective gardaí, who are armed but not assigned to ASU roles.
