A multidimensional grouping of the main theaters of military operations of the XX-XXI century on localization of injuries along the body contour and internal organs is carried out. The law of distribution of the proportion of head lesions in the total number of wounds is obtained. The possible upper limit of the head lesions proportion in the total number of injuries is estimated. Empirical equations for the change in the bullet flight energy, depending on bullet flight range for the main types of infantry ammunition are obtained. Requirements to an acceptance test method of a protective glasses material are formulated.
