កាំភ្លើងធុន​Bofors 75 mm (L/50 )

Bofors 75 mm and Bofors 80 mm were two closely related designs of anti-aircraft and general-purpose artillery. Less well known than the 40 mm quick-firing AA gun, the gun was nevertheless adopted by armed forces of numerous countries during World War II, including Argentina, China, Dutch East Indies, Finland, Greece, Hungary, Persia and Thailand.[1] It was closely related to the 8.8 cm Flak 18/36/37/41, one of the best-known AA guns of World War II, which was partially based on it.[1] Some pieces captured by the Japanese in China served as the blueprint for the Type 4 75 mm AA Gun, a reverse-engineered clone of the Bofors 75mm gun.
