Latvia’s national defense relies primarily on its integration into the NATO alliance, where Article 5 guarantees collective security against external aggression. According to the North Atlantic Treaty Organization, an armed attack against one ally is considered an attack against all members, forming the cornerstone of the Baltic state’s modern security framework alongside its professional national armed forces.
NATO Collective Defense and Article 5
The primary security umbrella protecting Latvia is the NATO alliance, which the country joined in March 2004 alongside fellow Baltic nations Estonia and Lithuania. Under Article 5 of the North Atlantic Treaty, member states commit to mutual defense in the event of an armed attack. According to NATO officials, this deterrent posture is reinforced by the presence of multinational battlegroups stationed in the region under the Forward Land Forces command structure.
To bolster regional deterrence, Canada leads the multinational NATO battlegroup stationed in Latvia at the Adāži military base. According to the Department of National Defence of Canada, hundreds of Canadian Armed Forces personnel serve alongside troops from other allied nations, including Albania, Czechia, Italy, Montenegro, Poland, Slovakia, Slovenia, and Spain, to maintain continuous rotational readiness.
National Armed Forces and Regional Cooperation
Beyond the NATO alliance, Latvia maintains its own professional military force, the Latvian National Armed Forces (Latvijas Nacionālie bruņotie spēki), which includes land forces, naval forces, air force, and the National Guard (Zemessardze). According to the Ministry of Defence of the Republic of Latvia, defense spending has steadily increased to meet and exceed NATO’s benchmark of two percent of gross domestic product, funding major modernization programs such as coastal defense systems, air defense batteries, and artillery acquisitions.
Regional defense cooperation further strengthens Latvia’s security position outside of traditional bilateral treaties. According to the Government of the United Kingdom, the UK-led Joint Expeditionary Force (JEF)—which comprises ten northern European nations including Latvia—provides a rapid-response framework designed to operate across the High North, North Atlantic, and Baltic Sea regions.
Strategic Context and Security Outlook
Latvia shares a border with Russia and Belarus, making its geopolitical environment a central focus of European security discussions. According to the Council of the European Union, member states also coordinate mutual assistance under Article 42.7 of the Treaty on European Union, which obliges EU countries to aid a member state victim of armed aggression on its territory.
As security dynamics in Eastern Europe continue to evolve, Latvian defense strategy emphasizes total national defense, combining active military deterrence, civilian preparedness, and deep integration with transatlantic and European allies to ensure territorial integrity.
