context_page_description: The AH-IV was a Czechoslovak-designed tankette used by Romania, Sweden and Iran during World War II. The Romanian vehicles saw action on the Eastern Front from Operation Barbarossa to the Vienna Offensive. Twenty vehicles were sold to Ethiopia after the war who used them until the Eighties. Romania also created a prototype, called R-1-a.
context_section_description: Sweden ordered forty-eight tankettes in 1937 as the Stridsvagn m/37 (Strv m/37) after a successful demonstration during winter conditions in the Krkonoše Mountains. They were to be assembled in Oskarshamn with a more powerful 4.39 litres (268 cu in), water-cooled, six-cylinder, 85 horsepower (63 kW) Volvo FC-CKD gasoline engine and armor, up to 15 millimetres (0.59 in) thick, from Avesta, although ČKD supplied most of the other components after building one prototype. The vehicle was heavily modified with the driver's machine gun deleted and proved to be the heaviest and largest version of the AH-IV at 4.68 tonnes (4.61 long tons; 5.16 short tons) and a length of 3.4 metres (11 ft), a width of 1.85 metres (6.1 ft) and 1.96 metres (6.4 ft) high. Its turret mounted two Swedish 8 mm (0.31 in) Ksp m/36 strv machine guns and sported a small observation cupola on its top. It carried a radio and 3960 rounds for its machine guns. It had a maximum speed of 60 kilometres per hour (37 mph) and a range of 200 kilometres (120 mi). It could ford a stream up to .9 metres (3.0 ft) in depth. The last components were shipped in November 1938.
