The Concept of a Poly-Functional Ballistic Shield [PDF]

open access: yesProblemy Mechatroniki, 2020
Police and military units are employing the use of additional, portable protection in the form of various types of ballistic shields ever more often. They are not only used for protecting a single operator, but rather entire assault groups or bystanders.
