the Estonian military is a compact force that relies heavily on conscripts and reservists and the support of its NATO allies; Estonia’s defense policy aims to guarantee the country’s independence and sovereignty, protect its territorial integrity, including waters and airspace, and preserve constitutional order; Estonia’s main defense goals are developing and maintaining a credible deterrent to outside aggression and ensuring the Estonian Defense Forces (EDF) can fulfill their commitments to NATO and interoperate with the armed forces of NATO and EU member states; the EDF’s primary external focus is Russia; since Russia’s full-scale invasion of Ukraine in 2022, Estonia has boosted defense spending, sent arms to Ukraine, and sought to boost the EDF’s capabilities in such areas as air defense, artillery, personnel readiness, and surveillance
Estonia has been a member of NATO since 2004 and is fully integrated within the NATO structure; since 2017, Estonia has hosted a UK-led multinational NATO ground force battlegroup as part of the Alliance’s Enhanced Forward Presence initiative; as the EDF Air Force does not have any combat aircraft, NATO has provided airspace protection for Estonia since 2004 through its Baltic Air Policing mission; NATO member countries that possess air combat capabilities voluntarily contribute to the mission on four-month rotations; NATO fighter aircraft have been hosted at Estonia’s Ämari Air Base since 2014; Estonia also hosts a NATO cyber security center; it cooperates closely with the EU on defense issues through the EU Common Security and Defense Policy and is a member of the UK-led Joint Expeditionary Force, a pool of high-readiness military forces from 10 Baltic and Scandinavian countries designed to respond to a wide range of contingencies in the North Atlantic, Baltic Sea, and High North regions; Estonia also has close defense ties with its Baltic neighbors and has bilateral military agreements with a number of European countries, as well as Canada and the US
the Estonian Army features a divisional headquarters, two infantry brigades, and an artillery battalion, plus supporting units; it would rely heavily on mobilized reserves during a crisis, which would be used to fill out active-duty units and staff territorial defense units; the Estonian Navy features a mine warfare flotilla; the EDF also has a special operations command (2023) (2024)
