According to the method for avoiding active protection of the tank to realize efficient damage, the fixed-height horizontal flying attack mode is adopted, the fixed-height horizontal flying height is larger than 20m, and the active protection distance of the main battle tank at home and abroad is 20m at the maximum, so that the active protection range of the tank can be avoided under the selected fixed-height horizontal flying height, and the weak part at the top of the tank is attacked while the active protection of the tank is avoided by combining the leading battle cooperation and explosion forming of the pellet warhead, so that efficient damage to the main battle tank is realized.
