The Czechoslovak Army (Czech and Slovak: Československá armáda) was the name of the armed forces of Czechoslovakia.

The Czechoslovak Army took part in the brief Polish-Czechoslovak War, in which Czechoslovakia annexed the Trans-Olza region from Poland.

In the Interwar period, the force was fairly modern by contemporary standards, with the core of being formed by four fast divisions equipped in the late 1930s with LT vz.

Partly mobilized after the German-Austrian Anschluss, and fully mobilized at the time of the Munich Conference, the force did not take part in any organized defense of the country against the invading Germans, due to the international isolation of Czechoslovakia.

However, with the Communist takeover of Czechoslovakia, it was Sovietised[4] and in 1954 was formally renamed the Czechoslovak People's Army.
