The Croatian Air Force Legion (Hrvatska Zrakoplovna Legija), was formed on June 2, 1941 as a foreign volunteer unit of the Luftwaffe with volunteers drawn from the Independent State of Croatia (Nezavisna Drzava Hrvatska). The fighter squadron served on the Eastern Front with great success from October 6, 1941 - July, 1944; the bomber squadron from October 25, 1941 – December, 1942. The HZL was then absorbed by the air force of the NDH and fought on Croatian soil until 1945.
