UFS 4-023-07 2 February 2026 UNIFIED FACILITIES SUPPLEMENT (UFS) APPROVED FOR PUBLIC RELEASE; DISTRIBUTION UNLIMITED DESIGN TO RESIST DIRECT FIRE WEAPONS EFFECTS UFS 4-023-07 2 February 2026 FOREWORD Unified Facilities Supplements (UFS) provide non-mandatory, supplemental information in support of Unified Facilities Criteria (UFC). Only UFC establish enforceable criteria. UFS are For Information Only (FIO) and exist to help users understand and apply UFC requirements. The purpose of UFS is to offer procedural guidance, best practices, lessons learned, examples, and explanatory materials that clarify how to meet UFC criteria. They may include step-by-step procedures, checklists, illustrations, or decision aids, but they do not create new requirements or modify UFC content. UFS are developed

of the equations in this chapter. The exception to that is Equation 5-4 for steel, which includes angles of obliquity. Another option is to provide high parapets that block sightlines to the roof. For this level of protection those parapets would either be sufficiently constructed to provide all the penetration resistance necessary or the combination of the parapet and the roof material would have to provide the resistance. Refer to the wall section of this chapter to design the parapets. Figure 5-10 shows a raised parapet configuration. UFS 4-023-07 2 February 2026 49 Figure 5-10.

s. In addressing window layout and placement, consider layouts and placements that do not allow sight lines to assets from outside the building using window configurations such as those shown in Figures 5-4 and 5-5. Alternatively, arrange rooms to ensure that potentially targeted assets cannot be seen through the windows or block sight lines through windows using screening materials such as fences or vegetation as described in Chapter 4.

An alternate approach is to design windows to limit sight lines through them by using translucent or figured glazing that allows light in but is not sufficiently transparent

position should detonate incoming contact-fuzed munitions. These screens supplement the protection inherent in the protected structure or position and reduce structure damage. The screen may be wood, sheet steel, fencing, metal mesh, and other acceptable materials. It may be solid material or open screen. Use open screens (e.g., chain link fence or metal mesh) when observation through the screen is required. For information on constructing and siting predetonation screens, refer to GTA 90- 01-011 and UFC 4-023-07. Note: Predetonation layers may provide overhead protection for expeditionary and temporary structures when incorporated with adequate shielding layers. 5.6.9. Unconventional Hardening.
