Army of the Czech Republic

The Czech Armed Forces (Czech: Armáda České republiky, lit. 'the Army of the Czech Republic'), also known as the Czech Army, are the military responsible for the defence of the Czech Republic as the main part of the Armed Forces of the Czech Republic (Czech: ozbrojené síly České republiky). The Czech Armed Forces led by the General Staff consist of the Land Forces, the Air Force, the Special Forces, the Information and Cyber Forces, the Territorial Forces, and other components.

Czech Army derives its legacy from the 15th century proto-Protestant Hussite Army, with many of today's units bearing names in honour of Hussite Army personalities or formations. Its modern history started with formal establishment of the Czechoslovak Legion fighting on the side of the Entente powers during the WW1, thus preceding the 1918 Czechoslovak declaration of independence. Following the Munich Agreement, the country was occupied by Nazi Germany and the Army was reconstituted in exile, fighting on the side of Allies of World War II in the European as well as Mediterranean and Middle East theatre. After the 1948 Communist Coup, the Czechoslovak People's Army with over 200,000 active personnel and some 4,500 tanks formed one of the pillars of the Warsaw Pact military alliance.

Following the Velvet Revolution and dissolution of Czechoslovakia, the Czech Republic joined NATO in 1999. The conscription was abolished in 2004, leading to transformation into a modern professional army inspired mostly by the British Armed Forces and USMC example. Today, the Czech Army has around 30.000 professional personnel and 4.900 members of active reserves. Additionally, any citizen can voluntarily join a five-week basic training without becoming a soldier or join advanced shooting training with their privately owned firearms and become a member of militia-style Designated Reserves.

A law adopted in June 2023 stipulates that the military expenditures shall not be lower than 2% of country's GDP, starting from 2024. In March 2025, Petr Fiala Government adopted a decision to raise the military expenditures annually by 0,2% of GDP, in order to reach at least 3% of GDP in 2030.
