The Nimrod was an anti-aircraft vehicle, based on a licence built copy of the Swedish Landsverk L-62.
Originally it was intended to be used as an anti-aircraft and anti-tank weapon. However it proved to be ineffective against armored vehicles, it was primarily used for air defence.
6 Swedish built Landswerk AA tanks equipped with the 40mm Bofors were supplied to the Finns. (Identical to the Hungarian vehicle.)
