1. A hard armor structure, comprising: a symmetrical array of hexagonal, regularly shaped armor grade ceramic tiles; anda metal lattice structure comprising rigid cell walls surrounding each tile made of strips of formed sheet metal in a side-by-side configuration, wherein the strips of sheet metal are formed in a repeating, three sided shape to define alternating, half hexagonal cells on either side of each strip. 2. The hard armor structure of claim 1 wherein the metal strips further comprise notches in the middle wall of each half hexagonal cell that alternate, such that along one side of the strip the notches are all on one edge, while on the other side of the strip the notches are all on the opposite edge. 3. The hard armor structure of claim 2, wherein the notches account for at least half the width of the strip, such that when adjacent strips are brought together, each notch on one strip receives a remaining half-wall of an adjacent strip. 4. The hard armor structure of claim 1 further comprising a solidifying agent applied to the tile array and lattice structure. 5. The hard armor structure of claim 4, wherein the solidifying agent is selected from the group comprising epoxies, polyurethanes, polyesters, vinyl esters, polyolefins, and acrylics. 6. The hard armor structure of claim 5, further comprising a ballistic resistant backing. 7. The hard armor structure of claim 6, wherein the ballistic resistant backing comprises a consolidation of high performance fibers. 8. The hard armor structure of claim 1, wherein the lattice structure material is one of the group comprising: polymer resin; fiber reinforced polymer composite; and ceramic. 9. The hard armor structure of claim 8, wherein the armor tiles are made of a first ceramic material, and the lattice structure is made of a second ceramic material. 10. The hard armor structure of claim 9, wherein the densities of the first and second ceramic materials are not the same.
