The Internal Security Corps (Polish: Korpus Bezpieczeństwa Wewnętrznego, KBW) was a special-purpose military formation in Poland under Stalinist government, established by the communist Council of Ministers on May 24, 1945.


The KBW consisted of 10 new cavalry regiments, an infantry division and two buffer brigades. The corps itself was subordinate to the Ministry of Public Security. By the end of August 1945, its force was made up of 29,053 soldiers and 2,356 officers. The KBW was called forth to protect key public infrastructure such as railways, but mainly to combat and suppress the anti-communist resistance in Poland including activities of the Cursed soldiers as well as all organizations which continued their armed struggle against the Communist takeover; such as the Freedom and Independence (WiN), the National Armed Forces (NSZ), and the remnants of the Polish Home Army (AK) among others.[1]

Between 1945 and 1954, the KBW fell under the responsibility of Minister Jakub Berman of the Politburo, who was in charge of the Ministry of Public Security. Later, it was part of the Ministry of Internal Affairs. Between March 1945 and April 1947 alone, units of the KBW killed over 1,500 members of the Democratic Underground known as the Cursed soldiers, wounded 301, and apprehended 12,200 others.

In 1965, the KBW was renamed as the Wojska Obrony Wewnętrznej (Internal Defense Force). It was included in the framework of National Defense. Also, in 1962, the Silesian Unit of the Engineering Army nr KBW-4 built roads in the Bieszczady region in the extreme south-east of Poland, strategically important but an uninhabited area.
