The Nimrod anti-aircraft tank was a Hungarian modification of the Svedish Landsverk L-62 tank with a license-build Bofors 38M 40mm gun mounted in a high open-topped turret overhanging to the rear.
The gun, traversed and elevated manually, protruded through a vertical slot in the curved turret front and the turret accommodated a commander, two layers, and a loader.
The prototype was produced in October 1941 at MAVAG in Budapest , and after successful field trials was accepted by the Army.

The Nimrod saw service from 1942 onwards in both AA and, less successfully, anti-tank (AT) roles.
It was deployed to both the 51^st and 52^nd Tank Destroyer Batallions of the 1^st and 2^nd Armoured Divsion resp. and saw extensive combat on the Upper Don in 1942/3, Galicia in April/May 1944 and the defense of the homeland from August 1944 onwards.

A total of 135 Nimrods were built until production ceased due to Allied air attacks and german occupation in 1944.

The Hungarians added some technical developments to their Bofors, and were the first to use them in combat in conjunction with radar fire control.
In one engagement against the Soviets at the River Tizer in 1943, Hungarian radar-controlled guns brought down all 25 attacking Petlyakov Pe 2 aircraft.

Late in the war, the vehicle was issued with the 42M "Kerngranate" round, a rocket grenade fitted over the muzzle in the fashion of a rifle grenade.
