A system for identifying a hard target from a distance. A delivery vehicle, such as a missile or bomb, is adapted to be dropped from the air. The delivery vehicle contains a plurality of hard target identifier or kinetic penetrator elements. Each of the elements has a nose portion of aerodynamic shape and a plurality of fins connected thereto. When ejected from the delivery vehicle, the elements will reach a substantial velocity, and hence, kinetic energy to penetrate partially into a hard target. A soft surrounding area, such as earth or water will absorb the elements. The elements may be passive for reflecting waves, such as acoustic waves or electromagnetic energy. Alternatively, they may be active elements capable of ejecting a dye, such as a fluorescent dye, or for transmitting acoustical or electromagnetic energy upon being activated.
