 In this way the Home Army was able to procure submachine guns (copies of British Stens, indigenous "Błyskawicas" and "KIS"), pistols ("Vis"), flamethrowers, explosive devices, road mines, and "Filipinka" and "Sidolówka" hand grenades.Hundreds of people were involved in the manufacturing effort.The Home Army did not produce its own ammunition, but relied on supplies stolen by Polish workers from German-run factories.
