The ATLAS network is an association of the police tactical units of the 27 Member States of the European Union established following the terrorist attacks of 11 September 2001 upon the initiative of the Police Chiefs Task Force.
ATLAS was initially informally established for information exchange and training activities co-operation between units and was later formalised by a Council decision in 2008 that also expanded ATLAS functions to include provision of assistance upon request to another Member State.
In 2018, an ATLAS Support Office was established in EUROPOL's European Counter Terrorism Centre (ECTC), therefore strengthening the role of the ATLAS Network within the European police organisations.
ATLAS uses the terms special intervention unit and crisis situation defined as:-
ATLAS recognises that a Member State may not have the means, resources or expertise to deal effectively with all crisis situations, in particular large crisis situations, and provides a framework for a Member State to request assistance from another member State.
ATLAS consists of 38 special intervention units including units from non-EU Member States Switzerland, Norway, Iceland, and the United Kingdom. The non-EU Member States can participate, including the use of all facilities, but have no voting rights.
