A minesweeper tank is a specialized tank equipped with specialized mine-clearing equipment, primarily used to clear pathways through anti-tank minefields. This equipment plays a vital role in tank units, helping them overcome obstacles like minefields and ensuring the smooth conduct of combat operations.

Mine-clearing tanks' mine-clearing devices are primarily divided into mechanical mine-clearing devices and rocket-blasting mine-clearing devices. Mechanical mine-clearing devices are further categorized by their operating principles into rolling, digging, and impact types. Rolling mine-clearing devices use rollers to crush mines, rendering them ineffective; digging mine-clearing devices use a bucket or similar device to excavate and remove mines; and impact mine-clearing devices use impact force to detonate or disable mines. These mechanical mine-clearing devices can be temporarily installed before combat, adapting to varying battlefield conditions.

On the other hand, the rocket-blasting minesweeper is a more efficient mine-clearing device. Mounted on the rear of the tank, it uses the force of the blast wave to detonate or destroy mines, quickly clearing a full-width path. Compared to mechanical minesweepers, the rocket-blasting minesweeper offers advantages such as faster path clearing, concealed launch, and more thorough clearance of non-explosion-resistant mines. However, it can also cause some damage to the surrounding environment due to the shock wave from the explosion.

In general, mine-clearing tanks and their mine-clearing equipment play an indispensable role in modern warfare. They not only quickly clear mine obstacles, ensuring the smooth advance of tank units, but also reduce casualties and equipment losses, thereby improving combat efficiency. With the continuous advancement of technology, the performance and efficiency of mine-clearing tanks and their mine-clearing equipment will be further enhanced in the future, providing a more solid guarantee for victory in war. There are many different types of mine-clearing tanks, each with its own unique design features and historical background. Let's take a closer look at the types of mine-clearing tanks you mentioned.

The PT-3 minesweeper tank was developed by the Soviet Union during World War II. As the first Soviet minesweeper, the PT-3 boasted a relatively simple yet practical design. It was equipped with two sets of steel rollers attached to the tank via a rotating truss mechanism. As the tank moved, the rollers would contact and roll over mines, neutralizing or detonating them, thus clearing a safe path for the tank troops. The PT-3 was widely used during World War II, providing crucial support to the Soviet Red Army's advance.

The Progvev-T jet mine-clearing tank was a very creative design of the Soviet Union during the Cold War.
