We claim: 1. A hard armor composite, comprising: (a) a rigid non-ceramic facing comprising high-performance fibers having a tensile strength greater than 7 grams per denier and at least one non-ceramic element selected from a group consisting of glass fiber, carbon fiber, and graphite; and said high-performance fibers and said non-ceramic element being arranged in a structure selected from a group consisting of woven layers, non-woven unidirectional layers, knit layers, a three-dimensionally knit structure, and a three-dimensionally woven structure; (b) a ballistic fabric backing carried by said facing, and comprising an array of bundled high-performance fibers, said fibers having a tensile strength greater than 7 grams per denier and a denier per filament ratio of less than 5.4; and (c) said rigid facing and fabric backing having a combined thickness of less than 0.900-inches, and a uniform areal density of no more than 5.1 pounds per square foot. 2. A hard armor composite according to claim 1, wherein said fabric backing comprises a plurality of overlying fabric layers. 3. A hard armor composite according to claim 2, wherein said fabric layers are laminated under heat and pressure to form a unitary ballistic structure. 4. A hard armor composite according to claim 1, and comprising means for adhering said fabric backing to said facing. 5. A hard armor composite according to claim 4, wherein said means for adhering comprises an adhesive selected from the group consisting of a thermoplastic polymer resin matrix and a thermosetting polymer resin matrix. 6. A hard armor composite according to claim 4, wherein said means for adhering comprises a polymer film. 7. A hard armor composite according to claim 4, wherein said means for adhering comprises an adhesive selected from the group consisting of an epoxy adhesive, a polysulfide adhesive, a polyurethane adhesive, a phenolic adhesive, a polyester adhesive, a polyvinyl butyral adhesive, a polyolefin adhesive, and a vinyl ester adhesive. 8. A hard armor composite according to claim 1, wherein said high-performance fibers are selected from the group consisting of aramid, ultra-high molecular weight polyethylene (UHMWPE), poly {p-phenylene-2, 6-benzobisoxazole} (PBO), and poly {diimidazo pyridinylene (dihydroxy)phenylene} (M5). 9. A hard armor composite according to claim 1, wherein said rigid facing comprising a generally flat, continuous monolithic plate. 10. A hard armor composite, comprising: (a) a rigid non-ceramic facing comprising high-performance fibers having a tensile strength greater than 7 grams per denier and at least one non-ceramic element selected from a group consisting of glass fiber, carbon fiber, and graphite; and said high-performance fibers and said non-ceramic element being arranged in a structure selected from a group consisting of woven layers, non-woven unidirectional layers, knit layers, a three-dimensionally knit structure, and a three-dimensionally woven structure; (b) a ballistic fabric backing carried by said facing, and comprising an array of bundled high-performance fibers, said fibers having a tensile strength greater than 7 grams per denier and a denier per filament ratio of no more than 2.0; and (c) said rigid facing and fabric backing having a combined thickness of less than 0.900-inches, and a uniform areal density of no more than 5.1 pounds per square foot. 11. A hard armor composite according to claim 10, and comprising means for adhering said fabric backing to said non-ceramic facing. 12. A hard armor composite according to claim 11, wherein said means for adhering comprises an adhesive selected from the group consisting of an epoxy adhesive, a polysulfide adhesive, a polyurethane adhesive, a phenolic adhesive, a polyester adhesive, a polyvinyl butyral adhesive, or a polyolefin adhesive, and a vinyl ester adhesive. 13. A hard armor composite according to claim 10, wherein said non-ceramic facing comprises a generally flat, continuous monolithic plate. 14. A hard armor composite according to claim 10, wherein said high-performance fibers are selected from the group consisting of aramid, ultra-high molecular weight polyethylene (UHMWPE), poly {p-phenylene-2,6-benzobisoxazole} (PBO), and poly {diimidazo pyridinylene (dihydroxy)phenylene} (M5).
