[The flight behavior of hand grenade fragments and their shock-producing effect on the human]

Systemic affects by multiple hits of corpuscular material are not seen until a level of ergy about 600-800 J is reached. A major determinant is the sum of energy. A potentiating effect could not be observed. Enduring casualties are expected by vital hits only, but heavy pains are able to induce serious handicap. The old rule of soldiers to avoid strong injuries, to lie nearby an armed handgrenade which is not possible to be thrown away seems to be corroborated by the present facts.
