Abstract: A vibratory countermine system and method associated with a propulsion means. The system is comprised of a ground-contacting percussion system assembly that is mounted to the front of the propulsion means. Also, a vibratory subassembly is mounted inside the ground-contacting percussion assembly for inducing vibrations in the ground. The ground-contacting percussion system is in contact with the ground ahead of the propulsion means. It transmits the vibrations, associated forces, and pressure waves below or ahead of the countermine system through the ground, thereby inducing the detonation of land mines.

Abstract: A hollow-shell road wheel for tracked vehicles includes a generally triangular, outer circumferential cavity formed by an outer rim and two wall members that extend radially inward at angles to a generally planar flange at approximately the mid-radius point of the hollow-shell road wheel. A series of hollow-shell road wheels assembled in a back-to-back configuration support the tracked-vehicle and act as guides for the track of the tracked-vehicle.
