The purpose of this UFC is to present engineering guidelines and cost effective solutions for protecting assets within fixed facilities against direct fire (antitank weapons and small arms) attacks. Those solutions will vary according to the applicable level of protection, which must be provided to designers as part of the design criteria. This UFC is intended to be used to refine preliminary countermeasures designs and protective strategies developed using UFC 4-020-02. This document provides guidance for design of new buildings and for retrofits of existing buildings against the effects of direct fire weapons.
Direct fire weapons, for the purposes of this UFC, are limited to small arms and shoulder fired antitank weapons. Small arms include ballistic weapons such as pistols, rifles, shotguns, and submachine guns up to 12.7 mm (0.50 caliber). Anti-tank weapons are limited to shoulder fired rockets such as the Russian RPG-7, RPG-18, and RPG-22 and the U.S. M-72 Light Antitank Weapon (LAW). For guidance on protecting against weapons outside of this scope, refer to UFC 3-340-01, Design and Analysis of Hardened Structures to Conventional Weapons Effects.
