They do not establish enforceable criteria—only Unified Facilities Criteria (UFC) are enforceable [UFS 4-023-07 Foreword]. UFS 4-023-07 offers procedural guidance, best practices, examples, and explanatory materials to help users understand and apply UFC requirements [UFS 4-023-07 Foreword].
Scope: The document addresses design strategies such as window placement and layout to limit sight lines to protected assets [UFS 4-023-07 Chapter 5], parapets for roof protection [UFS 4-023-07 Chapter 5], and screening materials (fences, vegetation) to block direct fire [UFS 4-023-07 Chapter 5]. It is referenced in Air Force publications for predetonation screen design and siting [AFPAM 10-219V2 para 5.6.9].

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.
