Armor includes a projectile impermeable material layer and a shock stiffening layer. The shock stiffening layer has opposing shock stiffening sublayers wherein each shock stiffening sublayer has a plurality of shock stiffening sublayer elements. The plurality of shock stiffening sublayer elements of opposed shock stiffening sublayers are interdigitated. The armor includes a foam layer wherein the shock stiffening layer is positioned between the foam layer and the projectile impermeable material layer. The plurality of shock stiffening sublayer elements of opposed shock stiffening sublayers may momentarily or permanently fuse in response to a projectile's impact. The shock stiffening layer spreads the energy laterally, thereby effectively mitigating the transfer of kinetic energy from a ballistic projectile directly to a region to be protected.
