The invention provides an armor plate for absorbing and dissipating kinetic energy from armor piercing 7.62 mm projectiles having a projectile length of from 32.8 mm to 37 mm, the armor plate comprising a plurality of ceramic pellets and a solidified material, each ceramic pellet having a body portion and a convexly curved end portion, each body portion having two opposite ends, an axis passing through each end and a substantially constant cross-section along the axis, and each convexly curved end portion extending from an end of the corresponding body portion, each body portion having a body portion length along the axis between the two ends, the ceramic pellets being embedded in the solidified material so that the solidified material retains the ceramic pellets in a ceramic pellet layer which is one pellet thick with the convexly curved end portions lying at or adjacent an impact receiving side of the armor plate, wherein the ceramic pellet layer is the only layer of ceramic pellets in the armor plate, wherein the ceramic pellet layer has an edge extending therearound formed by a subset of the ceramic pellets, wherein the ceramic pellets are arranged so that the body portion of substantially each pellet, other than of the pellets of the subset, lies in contact with or closely adjacent to the respective body portions of six neighboring ones of the ceramic pellets so that there are a plurality of valleys extending through the ceramic pellet layer with each valley being bordered by three adjacent ceramic pellets, wherein substantially each valley has a shape and size such that the diameter of the largest imaginary circle that will fit into the each valley between the neighboring body portions and substantially perpendicularly to the neighboring axes is from 1.96 mm to 3.7 mm, and wherein each body portion length is from 5.57 mm to 10.73 mm.
