The 44M "Buzogányvető" Páncéltörő Rakéta (English: Anti-Tank Rocket System Model 1944 "Mace Thrower") was an unguided anti-tank rocket designed in Hungary for use against Soviet heavy tanks and infantry during World War II.

In 1942, the Haditechnikaiintezet or "Institute of Military Technology" began work to develop a cheap and easy to produce weapon capable of destroying Soviet heavy tanks after Nazi Germany was unwilling to share technology related to their work on an experimental wire-guided missile.

Sources conflict as to whether the factory was destroyed or captured by Soviet forces on 20 December 1944, but either way production was halted entirely, and never resumed.

Because of the Soviet advance, Denk-Doroszlay requested to move his unit to Germany to continue there trials and training in order to form more batteries.

The tank is modified in many ways including the removal of the main gun (20mm Solothurn) and the engine cover being fixed into an open position to create the necessary flat area to mount the weapon.

Based on the fact that the engine cover is fixed into an open position, something dangerous to do in a combat situation, it can be confidently assumed that this is not a properly manufactured variant of the tank, but rather a field conversion.

Theoretically the weapon could be fired at and reach a target from up to 2,000 m (6,600 ft) in ideal circumstances, however the rocket was very inaccurate at this range.
