The Czechoslovak People's Army was the armed forces of the Communist Party of Czechoslovakia (KSČ) and the Czechoslovak Socialist Republic from 1954 until 1989. From 1955 it was a member force of the Warsaw Pact. On 14 March 1990 the Army's name was officially reverted back to the Czechoslovak Army removing the adjective "People's" from the name. The Czechoslovak Army was split into the Army of the Czech Republic and the Armed Forces of the Slovak Republic after the dissolution of Czechoslovakia on 1 January 1993.

The Czech Armed Forces, also known as the Czech Army, is the military service responsible for the defence of the Czech Republic as part of the Armed Forces of the Czech Republic alongside the Military Office of the President of the Republic and the Castle Guard. The army consists of the General Staff, the Land Forces, the Air Force and support units.
