The 40M Nimród was a World War II Hungarian self-propelled anti-aircraft gun based on a license-built copy of the Swedish Landsverk L-62 Anti I SPAAG but with a new turret, and developed independently. Originally, it was intended to be used both in the anti-aircraft and tank destroyer roles, but it proved to be ineffective against Soviet tanks like the KV-1 tank. Therefore, it was primarily utilized against lightly armored vehicles and for air defense. Design The 40M Nimród was a license-built variant of the Landsverk L-62 Anti I SPAAG. The L-62 Anti I was based on the chassis of the Landsverk L-60 tank which was already produced under license in Hungary as the 38M Toldi. The L-62 did differ though from the original L-60 chassis. It was longer and wider and had one more roadwheel per side. Besides that, the 40M Nimród differed on its own from the original L-62 Anti I design. While the chassis was basically the same as the L-62 Anti I, although utilizing parts from the 38M Toldi, the turret was modified to house one more crew member from the original 5 of the L-62 Anti I. The crew of the 40M Nimród consisted of six men: commander, driver, two loaders and two gunners. The vehicle's armament consisted of a Hungarian license-built Bofors 40 mm L/60 gun, in Hungarian service designated as 40 mm 36M (model of 1936), a gravity fed gun which had a rate of fire of 120 to 140 rounds per minute depending on the firing angle, which fired conventional ammunition at a muzzle velocity of almost . Ammunition for the gun consisted primarily of conventional high-explosive fragmentation and armor-piercing rounds, but also a specialized anti-tank round developed indigenously in Hungary. Hungarian armor-piercing ammunition for the gun could penetrate of rolled homogeneous armor at a range or , and at . The Nimrod carried 640 rounds, split into 4 stowages of 160 rounds each. Late in the war, the vehicle was issued with a muzzle loaded rifle grenade (or "shaft grenade" when referring to cannon calibers, ) designated 42M. This was a German Stielgranate 41 which had been modified to mount the 40 mm 36M gun instead of the German 3.7 cm Pak 36. It consisted of a German 15 cm hollow charge artillery shell (I.Gr. 39 Hl/A, ) mounted on a fin-stabilized tube meant to fit over the muzzle of the gun,
