1. A penetrator round assembly comprising: a main penetrator rod comprising a tungsten alloy; anda sacrificial solid nose engaged to the main penetrator rod, wherein the nose has a density that is greater than or equal to steel, wherein the nose is configured to perforate an explosive reactive armor cover plate and absorb the initial energy from and be eroded by movement of the cover plate. 2. The penetrator round assembly of claim 1, wherein the nose is a solid steel nose. 3. The penetrator round assembly of claim 1, wherein the main penetrator rod has a monolithic construction. 4. The penetrator round assembly of claim 1, wherein the main penetrator rod has a diameter of greater than about 24 millimeters. 5. The penetrator round assembly of claim 1, wherein the main penetrator rod has a length greater than 630 millimeters. 6. The penetrator round assembly of claim 1, wherein the nose has a length that is greater than about 100 millimeters. 7. The penetrator round assembly of claim 1, wherein a ratio of a length of the main penetrator rod and a diameter of the main penetrator rod is greater than about 25. 8. The penetrator round assembly of claim 1, wherein the main penetrator rods does not comprise depleted uranium. 9. The penetrator round assembly of claim 1, wherein the nose does not comprise depleted uranium. 10. The penetrator round assembly of claim 1, wherein a ratio of a length of the main penetrator rod and a diameter of the main penetrator rod is greater than about 25. 11. The penetrator round assembly of claim 1 further, wherein a ratio of a length of the main penetrator rod and a diameter of the main penetrator rod is greater than about 25,wherein neither the main penetrator rod nor the nose comprise depleted uranium, andwherein the main penetrator rod does not comprise cobalt. 12. The penetrator round assembly of claim 1 further, wherein the main penetrator rod has a monolithic construction,wherein the main penetrator rod has a diameter of greater than about 24 millimeters,wherein the main penetrator rod has a length greater than 630 millimeters,wherein the nose has a length that is greater than about 100 millimeters,wherein a ratio of the length of the main penetrator rod and the diameter of the main penetrator rod is greater than about 25,wherein neither the main penetrator rod nor the nose comprise depleted uranium, andwherein the main penetrator rod does not comprise cobalt. 13. The penetrator round assembly of claim 1 further, wherein the main penetrator rod has a monolithic construction,wherein the main penetrator rod has a diameter of greater than about 24 millimeters,wherein the main penetrator rod has a length greater than 630 millimeters,wherein the nose has a length that is greater than about 100 millimeters,wherein a ratio of the length of the main penetrator rod and the diameter of the main penetrator rod is greater than about 25,wherein neither the main penetrator rod nor the nose comprise depleted uranium,wherein the main penetrator rod does not comprise cobalt, andwherein when the steel nose impacts the cover plate of the explosive reactive armor (“ERA”) module, the steel nose absorbs an initial energy from a movement of the ERA cover plate without significantly bending the main penetrator rod. 14. The penetrator round assembly of claim 1 further, wherein the main penetrator rod has a monolithic construction,wherein the main penetrator rod has a diameter of greater than about 24 millimeters,wherein the main penetrator rod has a length greater than 630 millimeters,wherein the nose has a length that is greater than about 100 millimeters,wherein a ratio of the length of the main penetrator rod and the diameter of the main penetrator rod is greater than about 25,wherein neither the main penetrator rod nor the nose comprise depleted uranium,wherein the main penetrator rod does not comprise cobalt, andwherein when the nose impacts the cover plate of the explosive reactive armor (“ERA”) module, the nose absorbs an initial energy from a movement of the ERA cover plate without significantly bending the main penetrator rod.
