The AH-IV was a Czechoslovak-designed export armored fighting vehicle, classed as either a tankette or light tank,[2][3] used by Romania during World War II, but having also been acquired by neutral Sweden and Iran. Modified AH-IV versions were built under license by Romania (R-1) and Sweden (Strv m/37). The Romanian vehicles saw action on the Eastern Front from Operation Barbarossa to the Vienna offensive. Twenty vehicles were sold after the war to Ethiopia, who used them until the 1980s.
