preformed fragment(сокр. от "готовый поражающий элемент"; preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and size and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high velocity fragments produced by either method are the main lethal mechanisms of weapons, rather than the heat or overpressure caused by detonation Alex_Odeychuk)
