In one embodiment, a protective armor system includes first and second armor layers separated by a gap. The second armor layer has a hardness that is less the first armor layer. The protective shield is configured to disperse energy of a shaped charge, such as the energy within a penetrator generated by an explosively formed penetrator (EFP).

1. A protective armor system comprising: a protective shield configured to disperse kinetic energy of a penetrator generated by a shaped charge, the protective shield comprising:a first armor layer configured to receive the penetrator;a second armor layer separated from the first armor layer by a first gap, the second armor layer having a hardness that is less than the hardness of the first armor layer, the second armor layer configured to receive the penetrator that passes through the first armor layer; andan intermediate layer disposed in the first gap and attached to the first armor layer by a fastener, the fastener configured to release the intermediate layer such that the intermediate layer detaches from the first armor when the penetrator is received by the first armor layer, the intermediate layer configured to adhere to the penetrator as the penetrator passes through the gap,wherein, the force required to release the intermediate layer from the first armor layer is less than the force required to penetrate the first armor layer such that the fastener releases the intermediate layer from the first armor layer before the first armor layer is pierced by the penetrator. 2. The protective armor system of claim 1, wherein the intermediate layer comprises a plurality of copper foil sheets that are disposed adjacent one another. 3. The protective armor system of claim 1, wherein the intermediate layer comprises copper. 4. The protective armor system of claim 1, wherein the first armor layer comprises a ferrous alloy and the second armor layer comprises a non-ferrous alloy. 5. The protective armor system of claim 1, wherein a surface of the intermediate layer defines a plurality of perforations over its surface. 6. The protective armor system of claim 1, further comprising: a third armor layer separated from the second armor layer by a second gap, the third armor layer having a hardness that is substantially the same as a hardness of the first armor layer, andwherein the first armor layer and the intermediate layer are disposed proximate a first side of the second armor layer and the third armor layer is disposed proximate a second side of the second armor layer. 7. The protective armor system of claim 6, wherein: the first armor layer is composed of a first material;the second armor layer is composed of a second material; andthe third armor layer is composed of a third material. 8. The protective armor system of claim 1, wherein the intermediate layer is of a thickness between 1 mil and 375 mils. 9. A protective armor system comprising: a protective shield configured to disperse kinetic energy of a penetrator generated by a shaped charge, the protective shield comprising:a first armor layer configured to decelerate the penetrator;an intermediate layer that is attached to the first armor layer by a fastener, the fastener configured to release the intermediate layer such that the intermediate layer detaches from the first armor layer when the penetrator is received by the first armor layer;a second armor layer separated from the first armor layer by a first gap, the second armor layer having a hardness that is less than the hardness of the first armor layer, the second armor layer configured to decelerate the penetrator that pierces through the first armor layer; anda third armor layer separated from the second armor layer by a second gap, the third armor layer having a hardness that is substantially the same as the hardness of the first armor layer,wherein the first armor layer and the third armor layer are made of a first material and the second armor layer is made of a second material,wherein the second armor layer is disposed between the first armor layer and the third armor layer, andwherein the intermediate layer is configured to adhere to the penetrator as the penetrator passes through the first gap,wherein, the force required to release the intermediate layer from the first armor layer is less than the force required to penetrate the first armor layer such that the fastener releases the intermediate layer from the first armor layer before the first armor layer is pierced by the penetrator. 10. The protective armor system of claim 9, wherein the second gap has a different width than the first gap. 11. The protective armor system of claim 9, wherein the second armor layer comprises a non-ferrous alloy. 12. The protective armor system of claim 9, wherein the first armor layer comprises a ferrous alloy. 13. The protective armor system of claim 9, wherein the first gap is at least partially filled with a gas having an intrinsic speed of sound different from that of air. 14. The protective armor system of claim 9, wherein a surface of the intermediate layer defines a plurality of perforations over its surface. 15. The protective armor system of claim 9, wherein the intermediate layer is formed of a material selected from the group consisting of woven fabric, titanium oxide, and aluminum oxide. 16. The protective armor system of claim 9, wherein the second armor layer is disposed obliquely to the first armor layer. 17. A protective armor system, comprising: a first armor layer configured to receive a penetrator generated by a shaped charge;an intermediate layer attached to the first armor layer by a fastener, the intermediate layer having a thickness that is less than the first armor layer, the fastener configured to release the intermediate layer from the first armor layer when the penetrator is received by the first armor layer, the intermediate layer configured to adhere to the penetrator as the penetrator passes through a gap; anda second armor layer separated from the intermediate layer by a gap, the second armor layer configured to receive the penetrator that passes through the first armor layer and a portion of the intermediate layer detached from the armor layer, andwherein, the force required to release the intermediate layer from the first armor layer is less than the force required to penetrate the first armor layer such that the fastener releases the intermediate layer from the first armor layer before the first armor layer is pierced by the penetrator. 18. The protective armor system of claim 17, wherein the intermediate layer comprises a curved layer that is preloaded with a spring loaded stress. 19. The protective armor system of claim 17, wherein the intermediate layer comprises copper. 20. The protective armor system of claim 17, wherein the intermediate layer comprises a plurality of copper foil sheets that are disposed adjacent one another. 21. The protective armor system of claim 17, wherein a surface of the intermediate layer defines a plurality of perforations over its surface. 22. The protective armor system of claim 17, wherein the fastener selected from the group consisting of an adhesive, pegs, bolts, clips, and clamps. 23. The protective armor system of claim 17, wherein the first armor layer has a hardness that is greater than a hardness of the second armor layer. 24.
